Science meets industry

The 25th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC), which is taking place at the beginning of September,

has called up reinforcements. Under the aegis of the 5th World Conference on Photovoltaic Energy Conversion , this year’s EU PVSEC is being held to-gether with the 36th US IEEE Photovoltaic Specialists Conference and the 20th Asia/Pacific PV Science and Engineering Conference. It is therefore no surprise that the conference once again promises to outdo itself in terms of superlatives: 4,500 delegates are expected to discuss the latest developments and trends at the conference, which will be holding more than 1,600 specialist talks. Last year, there were around 1,300 lectures and almost 4,000 delegates.

The lectures are divided into six conference cate-gories: Advanced Photovoltaics, Wafer-Based Silicon Solar Cells, Thin-Film Solar Cells, Components, PV Systems and Large Scale Deployment.

A highlight of the conference will be the awarding of the 18th European Becquerel Prize, which is con-ferred for outstanding contributions to the develop-ment of photovoltaic solar energy. The award has been named after French physician Alexandre Edmond Becquerel, who discovered the photovoltaic effect in 1839. Last year, the prize went to Alexander Bett from Fraunhofer ISE for his contribution to devel-oping concentrator solar cells.

The trade fair has also grown again: 950 exhibi-tors from more than 100 countries are expected at the trade fair, which will cover an area of 80,000 m2. As would be expected, most of the exhibition area will be taken up by production system providers and so-lar cell and module manufacturers, who will respec-tively take up 37 % and 40 % of the space. The rest of the exhibition area will be filled by manufacturers of mounting systems, trackers, inverters, batteries, cabling and connector systems along with system suppliers and project developers.

The Spanish module manufacturer Isofotón is to present the ISF-240 in Valencia. Isofotón state that it is their “most powerful module to date”, with an out-put of 240 W and an efficiency of 14.5 %. Isofotón employ three instead of two conductive paths that are connected to the cells in order to minimise losses caused by electrical resistance. The module has a new circuit and an enhanced waterproof junction box, which will allow for improved heat dissipation. The aluminium frame of this new development is anod-ised and features a 20 micrometres thick anti- corrosion coating. The ISF-240 is available now.

There is more news from Isofotón apart from their product range. Since June, the company has had a new owner, the Spanish-South Korean consortium Affirma-Toptec, and a new CEO, Angel Luis Serrano. The consortium state they want to place a € 50 million investment, largely intended to promote the develop-ment of Isofotón in core markets such as Germany , Italy, Spain and France. In addition, the manufacturer

plans to expand internationally and develop new markets in Asia and the USA. In light of this, produc-tion capacity is to rise to 500 MW during the next three years.

Centrosolar AG bring along their new 54 cell module to Valencia. The new item in the product range in-cludes four additional cells and an increased capaci-ty of up to 225 W in comparison to the previous SClass-Excellent series. With the relaunch, the com-pany says they are responding to the wishes of many customers for a PV module with a high output and limited size. The new module consists of six strings with nine cells each instead of 5 strings with 10 cells each. It is therefore wider and shorter and thus pro-vides for improved structural and torsional rigidity on the roof. The new format aids the installer in handling the modules, which is reflected in shorter assembly times. Centrosolar state that the additional row of

cells allows for an efficient wiring concept that lowers resistances inside the module, providing higher

Trina Solar, who manufacture ingots, wafers and so-lar modules, are to present two new modules in Valencia: the high-performance utility-scale module TSM-PC14, and the TSM-DC80 with Quad-Max tech-nology. The former is especially important for large ground-mounted plants and is fitted with 72 multi-crystalline cells. Its peak output is at 265-290 W. From the fourth quarter of 2010, the module will be avail-able in North America and Europe.

The second new addition, the module TSM-DC80, has been designed specifically for roof systems. Thanks to its square shape and the em-ployed “Quad Max” technology, the mod-ule’s monocrystalline cells could collect far more sunlight than conventional cells while avoiding the surface loss typical for octagonal cells. Trina Solar promise a per-formance boost of up to 8 % compared to other monocrystalline modules on the market. The launch of the TSM-DC80 in Europe and North America is scheduled for the first quarter of 2011.

There is a new cell format available from Sunways AG. In March, the company, having worked with the Insti-tute for Solar Energy Research Hameln (ISFH), devel-oped monocrystalline silicon solar cells with screen-printing metallisation and with over 19 % efficiency in the 5-inch format. They have now developed a pro-totype in the 6-inch standard format. Particular em-phasis was placed on a high efficiency of the rear side of the cells in order to improve the yield in the long-wave range of the solar spectrum. Sunways mention up to 5 % more output per cell.

The Taiwanese manufacturer Neo So-lar Power (NSP) specialises in the de-velopment and manufacture of high performance solar cells. The compa-ny, founded in 2005, is presenting their “Perfect 18” monocrystalline so-lar cell in the 6-inch format and an ef-ficiency of 18 % at their booth in Va-lencia. In addition, NSP is to present their multicrystalline solar cell “Per-fect 17”, which is also available in the 6-inch format. They state the cell

achieves an efficiency of 17%. Both new develop-ments are suitable for multicrystalline 245 W mod-ules or monocrystalline 255 W modules with a 60-cell

configuration. They are slated for series production in the fourth quarter of 2010.

Under the brand name “gehrtec”, Gehrlicher Solar AG from Dornach, Germany, brings products from their own research and development department to the market. With the new development gehrtec Front, a PV façade system is available for the first time. The attachment for the curtain-type rear-ventilated sys-tem is based on common and approved façade sub-structures on which the gehrtec carrier rails are mounted. According to Gehrlicher, the use of large laminates made by ENN Solar and Masdar PV with backrails stuck to the back makes the installation easier, meeting the demands of façade engineers in terms of cost, ease of installation, serviceability, de-sign and functionality. The launch of the system in Germany is scheduled for Q4 2010 / Q1 2011. At the same time, the product is to be available in the Czech Republic, France, Greece, the UK, Italy and Spain.

The gehrtec Intra has also recently been added to the product portfolio. This roof-integrated system is fully integrated into the roof in a way that the mod-ules themselves serve as the water-repellent surface. To this end, First Solar modules are used as they can be individually removed from the roof. Attachment is achieved with profiled rails and rubber seals. To help the installer during the installation process, he re-

ceives a pre-assembled mounting system. After at-taching the profiled rails, the modules are simply in-serted into the holders so other tools are not re-quired. On request, the system can be configured for different frameless modules.

As the module measures 1,662 x 990 mm, there are two additional horizontal struts on the rear side of the module which provide for improved stability. The module is certified for a load of 5,400 N/m². The de-sign of the module is such that the black frame goes well with the dark solar cells to create an overall har-monious result. The company relies on soldering instead of terminal connections for connecting the junction box. From the processing of the raw materials to cell and module manufac-turing, it all happens in their own production fa-cilities.

Sovello AG have added a high-voltage module to their portfolio, thus offering both low-voltage modules for large open areas as well as higher voltage modules for small roof areas.

The new high-voltage configuration of the T-se-ries, which replaces the low-voltage configuration of the T-series, is characterised by a special adjustment to satisfy parameters of commercial inverters for small installations. The design of small solar power systems is thus simplified and the performance of the whole system optimised.

The Arnold Group is presenting its combined surface and chamfering grinding machine 72/865 for silicon blocks. The system is designed for small and medium- sized production volumes. The process part of the machine bed is moulded with a mineral casting, which ensures considerable machine stiffness and high damping. The entire system weighs around

9.2 tons. The grinding machine uses little cooling wa-ter: the grinding process is fed with only 40 l/min with up to 25 bar. The combined system can process workpieces with widths and heights between 125 and 210 mm with a maximum length of 500 mm. The grinding spindles, with a diameter of 250 mm, work at a maximum rate of 60 m/s and are driven by 9.1 kW motors .

Recently introduced in May, the optional Arpat software enables you to record and analyse the pro-cess data from the machine. Using various sensors, the system is able to capture data on the water and energy consumption, axis positions, torques, cutting and feed rates and saves these data in a database. The parameters can be visualised directly on the ma-chine or using a web browser via a local network. The system is set to go on sale in January 2011.

Balver Zinn from Germany is presenting its range of solders, anodes and special cored and solid wires at EU PVSEC. Through its Cobar subsidiary, Balver Zinn is also now also offering soldering flux that can be used to treat the surface of diverse oxidised surfaces. The flux is used when stringing solar cells. The con-ducting paths are dipped in the flux or sprayed with it in order to be cleaned and moisturised. The range of products covers alcohol-based, low-solvent and solvent-free solutions. For example, the solutions from Balver can be used to clean difficult surfaces such as AgAl.

For those who like soldering their solar cells themselves, Balver Zinn provides flux pens with which you can work by hand.

US company BTU supplies thermal treatment prod-ucts used for manufacturing solar cells. For example, the Tritan Metallization Firing System is used for the metallization of solar cells and provides a tempera-ture gradient of 200 °C per second. By deploying sep-arated conveyors that can travel at different speeds during each working stage, the drying and cooling sections are not compromised. For this reason, solar cells leave the Tritan line at a standard temperature of 40 °C and optionally at 25 °C. Normally, temperatures would be above 60 °C. The dryer operates in a tem-perature range between 100 and 350 °C, and the fur-nace unit between 200 and 1,000 °C. The Tritan sys-tem works with wafers with edge lengths of 125 x 125 mm and 156 x 156 mm.

For phosphor diffusion, BTU provides the Meridian In-line Diffusion system. Meridian operates between 800 and 1,000 °C in order to drive phosphor from a coating into the silicon wafer. The temperature can be controlled to a preciseness of ±2 °C. Meridian can be operated with a maximum throughput of 1,500 wa-fers per hour. The system is loaded with wafers with edge lengths between 125 and 210 mm.

The Italian film manufacturer Coveme is presenting a new innovation from its dyMat PYE film product range, which is used for the rear sides of PV modules. The polythene-based dyMat PYE 3000 film, which was developed together with DuPont Tiejin Films, is named after a 3,000 hour damp heat test passed by the new product. Coveme thus assumes that the ser-vice life will last considerably longer than 25 years.

The cell side of the film is coated with a 100 μm thick primer that offers adhesion of at least 40 N/cm against EVA (ethylen vinyl acetate). Corona treatment is also available on request, which increases this val-ue to more than 80 N/cm. The primer is available in different colours and can also be transparent. The

laminate has an air moisture permeability of just 2.40 g/m2d. The breakdown voltage is just 20 kV.

anti-reflective coating and lamination processes. These operations are all key to the quality of photo-voltaic cells. The SolarPaq system travels through the furnace or thermal process, measuring a time temper-ature profile directly from the product.

The SolarPaq Anti-reflective Coating System pro-vides temperature profiles from the solar cells as they pass through the silver nitride coating process. This is typically conducted using a plasma sputtering pro-cess. For the first time, manufacturers can now mon-itor the cell temperature profile even when the plas-ma is energised. According to Datapaq, this system has been designed so that it simply takes the place of one of the cells in the carrier, which means that it is not necessary to modify the expensive carrier.

Finally, the SolarPaq Vacuum Lamination System is used to profile the final assembly stage of the solar modules. An all-new thermal barrier ensures that the data logger is protected not only from the heat creat-ed from the lamination process but also from the ap-plied external pressure. A unique external barrier frame prevents stress points occurring on the vacuum membrane.

Maschinenbau Gerold GmbH has expanded its prod-uct range this summer with the HMA system, which can be used to seal the edges of thin-film modules with liquid butyl. Although butyl tape is normally de-ployed for this, Gerold claims that using liquid butyl improves the quality of the sealing. For example, the edge sharpness and application preciseness is great-er relative to adhesive tape. Less material is also used than with tape, as there is no waste material and liners are no longer needed. Instead, the liquid butyl can be delivered in comparably cheap vessels. Depending on the throughput, one or two dispensers are deployed that apply the butyl to the module edges , achieving cycle times of between 25 and 60 seconds per module.

The HMA system can be expanded by also cutting and inserting films in the butyl frames. As the third production stage, the HMA system is also able to combine glass-glass modules.

As its name would suggest, British adhesive tape manufacturer Hi-Bond Tapes relies on adhesive tapes to seal modules. The reason given by the company was the long curing time required by liquid sealing material, whereby adhesive tape enables modules to be further used more quickly. Hi-Bond Tapes relies on acrylic adhesive tapes, which promise to provide im-proved long-term stability compared with conven-tional polyethylene or polyurethane adhesive tapes. They are temperature-stable, impermeable to mois-ture and UV-stable for temperatures between -40 and 160 °C. Depending on the model, acrylic tapes have an 180° peel strength ranging between 3.1 and 3.35 kg/cm2 and a tensile strength between 6.8 and 5.5 kg/cm2. Without requiring any special pre- treatment, the tapes adhere to aluminium, glass as well as rear-side films and rails.

The German InnoTech company was founded in 2009 by the former Managing Director of Meier Solar Solutions , Hans-Gerd Stevens. Although the company is still very young, its range of Incapcell laminators of-fers a very wide spectrum of lamination possibilities. For example, the laminators enable inverse- lamination, utilising a heating plate beneath the modules to pre-warm them. Pressing the plate against a second heat-ing plate above the modules enables rapid heat trans-fer. The process also enables very rapid throughput rates. For example, fast-cure EVA processes can be achieved in 9 minutes and ultra-fast cure processes can be achieved in less than 7 minutes. When deploying thermoplastic encapsulation materials such as PVB or silicon, the Incapcell laminators achieve process times between 12 and 13 minutes.

A complete heating and cooling process can also be realised in the laminators in which an upper and lower membrane are pressed against the respective upper heating and lower cooling plates. This makes the downstream transportation to a cooling station superfluous.

The laminators are modular in design and can al-so be expanded during ongoing production. For ex-ample, the laminators can be first of all set up hori-zontally and then later stacked like pallets. Each lam-inator is operated autonomously, so that if a lamina-tor is being serviced, the production on the others can continue.

The heating behaviour of the heating plates can also be individually configured. For example it is pos-sible to work with circulating oil or several heating levels. All electric and hydraulic connections for the heating plates are positioned outside the vacuum chamber. Furthermore, the heating elements do not have direct contact with the thermal oil. If required, it is possible to set the temperature to the nearest ± 1 °C.

At the Manz Automation AG booth, trade fair visitors can find out about its new CIGS production technolo-gy, which Manz has added to its production range through a licence agreement with Würth Solar GmbH. The production line is based on the technology from Würth Solar, which has been operating around the clock in a 30 MW plant since 2006. The production lines can produce thin-film modules with a peak effi-ciency of 12.8 % across an area of 600 x 1,200 mm. Würth’s CISfab in Schwäbisch Hall is also available for further developing the production technology and qualifying new processes and materials.

In addition to its thin-film technology, the compa-ny is also presenting its range of products for crystal-line silicon photovoltaics. For example, the company offers a one-step selective emitter. Using a pulsed la-ser that scans the cell surfaces, this generates local-ly highly doped areas by diffusing liquid-phase phos-phorus from PSG glass. The conduction paths are then specifically applied to these areas. This produc-

At EU PVSEC, Meco Equipment Engineers BV from the Netherlands will be presenting its Cell Plating Line (CPL) for the metallization of crystalline solar cells. The Meco CPL is based on the proven concept provided by the Meco EPL, which has been installed more than 300 times worldwide and has estab-

lished a reputation in the semiconductor world for lead frame plating applications. According to Meco, the CPL solution offers tangible improvements in terms of cell efficiency: a fine line and seed layer of silver paste is printed onto each cell, whereby the electrical conductance of the contact finger is further enhanced by electroplating either Ag or Ni-Cu-Sn onto it. This produces a narrow contact fin-ger while simultaneously improving the resistance value; this in turn im-proves the absolute cell efficien-cy by up to 0.5 %. This also re-duces the consumption of costly silver paste, as only a narrow and thin seed layer is required. The total CPL capacity is 50 to 100 MW / year. In ad-dition, the Meco CPL offers other interesting features such as vertical cell transportation, which reduces the drag over of chemicals compared with plating methods using horizontal cell transporta-tion. This enables a very low consumption of chem-icals and considerably reduces the amount of wastewater. A unique contact belt design makes it possible to plate on the front side, rear side or on both sides. The CPL also offers two metal alterna-tives: Ag or Ni-Cu-Sn plating. These can be used in applications where metallization is applied directly to silicon. Meco promises an overall ROI of less than one year.

Meier Solar Solutions is presenting its new Stacolam 10x23/17/TSL stack laminator, which with up to 10 trays can attain a capacity of up to 250 MW a year. In contrast to its predecessor, this new model has an ac-tive pin lift for each tray. This means that the pins are not forcibly guided and, when the membrane is pressed on, the pins are not automatically reinserted but are independently controlled, as is the case with conventional laminators. This increases the process security of the machines. The individual trays are sep-arated to enable the laminator to also operate when not fully loaded. Trays not required are switched off at

fixed to standardised workpiece supports made of high-strength plastic (PET). For gently transporting thin-film modules and panels between individual process stations, Montech provides twin-, triple- and quadruple-belt conveyors with cogged belts. The transport conveyor for modules has two different drive versions with a spur gear motor as well as de-fined acceleration and braking ramps.

Oerlikon Leybold Vacuum is presenting its new Dryvac dry screw technology pump series for produc-ing thin-film silicon solar cells. The Sprinter and Enduro versions of the Dryvac system have optimised pumping speeds at pressures >10 mbar to provide fast pump downtimes. These models are especially suited for short-cycle operation. Models from the Dryvac Champion range were designed to provide high reliability in harsh process conditions. They are optimised for handling typical production gases used in the photovoltaic industry. The energy consumption of the pumps is relative low. With a pumping speed of 650 m3/h, they have a power consumption of 7 kW below 20 mbar. Depending on the model, a vacuum from 1x10-2 to 1x10-3 mbar can be achieved.

the press of a button via the process control system. It is also possible to service the vacuum system dur-ing ongoing operation. This enables a vacuum pump to be activated while a second one is undergoing servicing.

The new stack laminator utilises the so-called TSL system that encapsulates the laminate in three stages . After the conventional lamination, the lami-nate is pressed in a heating press and then in a cool-ing press. The presses are based on a concept that dispenses with membranes and hydraulic surface pressure.

The stack laminators are modular in design and can also be subsequently adapted to meet the cus-tomer’s current capacity requirements. For example, a 6-tray laminator can later be expanded to 10 trays.

Montech is showcasing a new vacuum conveyor that transports wafers overhead at a speed of two metres per second. The vacuum conveyor enables several wafers to be handled at the same time. In contrast to conventional conveyor systems, the conveyor belt does not require return journeys. A further product in-novation for transporting carriers is the use of a flow-through transfer system. In accordance with the as-sembly processes, this enables the carriers to be au-tomatically fed from one conveyor belt to the next and through the necessary workstations. The carriers are

Reis Robotics (Germany) is appearing in Valencia with two innovations: the company’s newly developed, automatic electroluminescence system for measuring the strings and the matrix makes it possible to iden-

tify and immediately reject faulty or damaged solar cells. This is achieved automatically with a high-resolution camera-based system within a few sec-onds. This enables defective cells to be quickly repaired or replaced and imme-diately used again in the production process. An expanded system enables the entire matrix to be evaluated prior to the lamination pro cess. This new quality assurance system, which inter-venes at a very early stage in the pro-duction pro cess, prevents faulty cells from rendering modules unusable. An-other major advantage for manufactur-ers is that the system can be easily retrofitted into existing lines with min-imum expenditure.

The second highlight in Valencia relates to the fully automatic assembly of junction boxes. In this pro cess, the contacting and installation of the junc-tion boxes occur after the strings have been laminated in the module. Accord-ing to Reis Robotics, distinguishing

features of this process include its high security and savings potential because it enables several stages to be omitted such as foil stamping and manual threading of contact leads prior to lamination. In ad-dition, because ethyl vinyl acetate is not released during lamination, this prevents soiling of the lami-nator membrane. The automatic assembly process enables savings to be made and can reduce the re-quired amount of contact leads by around 10 %. The automatic positioning and connection of junction boxes can also be retrofitted in production lines at any time.

A directional solidification furnace for preparing poly-crystalline silicon will be introduced to visitors at EU PVSEC by Italy’s Saet Group, the international induc-tion solution provider. The company is launching its new line of IDSS products for refining silicon. The di-rectional solidification furnace for preparing poly-crystalline silicon is based on the induction technol-ogy deployed by the group since 1966. This unique process was developed in a project launched 2 years ago as part of a study conducted in collaboration with the UCLA, USA. Saet claims that it is a “groundbreak-ing solution” that reduces power consumption by more than 25 % and increases the global furnace throughput by 20 % in comparison to current conven-tional DSS electric furnaces. The IDSS’s unique fea-tures do not include wearing components such as re-sistors and an independent heating zone fed by the latest generation of IGBT power devices. This results

in high quality refined silicon at a lower production price. The first IDSS unit is already available for testing, live demonstrations and material pre- production.

Schiller Automation has introduced a new junction box system, combining surface mounting and con-tacting application technology, which is designed for both crystalline and thin-film photovoltaic modules. The system is fully automated in production and re-quires no manual intervention. The contact ribbons have no de-orientation pre or post lamination. This enables, for example, cycle times of 20 seconds to be achieved for 60 cell crystalline or thin-film modules in any GEN5 format. In collaboration with Henkel, a spe-cial adhesive system has been developed for this ap-

Sono-Tek Corporation from the USA is presenting its ultrasonic system for applying anti-reflective coat-ings to solar glass. The HyperSonic System is de-signed to coat large glass areas up to 122 cm in width. The procedure is considered to be cheaper than traditional CVD and PVD processes because it operates more quickly and does not require a vacu-um. The constant ultrasonic vibration of the nozzles prevents the nano suspensions commonly used in anti-reflection coatings from agglomerating. The sys-tem can control the deposition thickness and the droplet size by varying the vibration. These proper-ties also improve the quality of the coatings relative to conventional nozzle systems, as the ultrasonic nozzles create a pressureless atomised spray. This means that the droplets coming off the nozzle tip

At PVSEC, Tyco Electronics is presenting its new, medium-sized four-rail junction box for solar module foil connections. Thanks to its low profile of just un-der 13 mm, the compact junction box can be easily mounted to the rear side of solar modules using sili-con adhesive or double-sided adhesive tape. The flat construction has been achieved using surface mount-ed device (SMD) diodes, which are mounted on very wide internal power rails.

With its decentralised two-rail junction box, Tyco offers an interesting alternative to the standard type of centralised junction boxes normally used. With this concept, two junction boxes are positioned in sepa-rate corners of the solar module with an additional box in the centre. Compared with the centralised junction boxes commonly used at the moment, the decentralised design requires 50 % less jumper cable to connect to the next solar module as shorter cross connections can be used.

Both products accord with the IEC 61215 ed.2 (VDE V0126-5) specification.

The Belgium based research company Imec will show-case its latest advances in solar cell technology, such as “record efficiencies on crystalline Si solar cells fab-ricated on a quasi industrial process”.

One of Imec’s highlights will be larger area solar cells based on an epitaxial thin-film silicon technolo-gy. Imec makes use of a process called epitaxial growth. This means, small silicon crystals grow on a substrate and adapt the same crystal structure that the substrate has. With this process, Imec has reached cell efficiencies of up to 16.3 % on high-qual-ity substrates and efficiencies of up to 14.7 % on low-quality substrates, the latter one showing the po-tential of the technology for industrial manufacturing. The results were achieved within Imec’s silicon solar cell industrial affiliation program (IIAP) that explores and develops advanced process technologies aiming a sharp reduction in silicon use, whilst increasing cell efficiency. “By implementing copper-based contact schemes, we can further increase the efficiency mak-ing epitaxial thin-film silicon solar cells on low-cost wafers an interesting industrial technology.” said Jef Poortmans, Director of Imec’s Energy/Solar pro-gramme.

Furthermore, Imec developed a spray coating technique for organic solar cells that reaches an ef-ficiency of more than 3.7 – the same as reference spin coated devices. With the development of two-solvent systems for each of the materials to be de-posited, Imec achieved smooth and uniform poly-mer thin films with excellent optical and electronic properties via a large-area, roll-to-roll compatible technology that could replace spin coating and ena-ble the inexpensive production of organic solar cells.

Regarding Imec TPV research, Imec developed an improved processing technique for germanium-based thermophotovoltaic (TPV) cells resulting in significant reduction of cell cost, an essential step to develop a market for thermophotovoltaic applications. Imec’s newly developed TPV cells are fabricated on germani-um substrates with a rough surface, instead of the traditionally used substrates with expensive mirror-polished front surfaces.

Back in 2009, Imec launched an industrial affilia-tion programme (IIAP) on crystalline Si PV, which companies such as Schott Solar, Total, GDF Suez and Photovoltech already joined.

Gebr. Schmid GmbH is showcasing a whole series of products for processing and handling wafers and solar cells. These include an inline system for pre-cleaning and de-gluing sawn wafer blocks. It cleans the wafers using a “ceramic beam” process in which the cleaning agent flows through interior channels and kerfs creat-ed when the ingot is sawn in the ceramic beam, before being distributed evenly over the entire wafer surface. The system achieves a cycle rate of four wafer blocks per second and is suitable for 500 mm and 1,000 mm plates. The company is also presenting an inline mod-ule for light-induced galvanisation of solar cells on the emitter side. In the first step, the front-side conducting layers are applied, for example using the inkjet print-ing process. In order to improve the electrical conduc-tivity of the contact lines, silver is applied galvanically in the second step. The illuminated solar cell provides the required polarity for the cell’s front side.

At EU PVSEC in Valencia, the SEM S.r.l. company from Italy is launching its SPIM electronic device. It con-sists of two electronic units: the SPIM Slave and the SPIM Master.

Whilst the Slave is embedded in the PV module junction box, the Master is a stand-alone unit. Ac-cording to the company, SPIM enables PV modules to be integrated into wireless communication net-works. Each PV module is treated as a single unique node within each network, whereby the network is driven by an external “master coordinator” that con-trols up to 200 PV modules. According to the manu-facturer, the main functions include monitoring the functional parameters of every single PV module, comparing actual and expected field performances, providing theft and fire protection and measuring the power output of every single PV module regard-less of the size of the solar farm. The Slave device monitors electrical parameters such as current, volt-age, power and temperature, and compares the measured values with the manufacturer’s specifica-tions.

Solare Datensysteme GmbH is coming to Valencia with its new evaluation and monitoring programme.

Its Solar-Log WEB is a moni-toring portal with six different expansion levels. The scope of services is tailored to dif-ferent users, ranging from private and commercial op-erators to installers and wholesalers who want to monitor several systems.

Its free “Self Made” solution enables private system operators to cre-ate and configure their own homepage. The so-lution offers basic func-tions ranging from event reports, yield overviews per installed kW to the calculation and depic-

tion of avoided CO2 emissions. Operators of existing systems and users of the previous Solar-Log Internet service can continue to use the previous Solar-Log “Home Edition” in its familiar form as the Solar-Log WEB “Classic 1st Edition”.

Solar-Log WEB “Full Service” is a service for pri-vate customers who monitor and service their sys-tems with professional support from installers. In addition to the basic functions, it offers supplemen-

tary add-ons such as remote configuration of the Solar-Log device or centralised fault monitoring and reporting for several systems. This version enables up to four email addresses to be set up for sending yield and fault messages. Solar-Log WEB enables in-stallers and wholesalers to monitor and evaluate all installed systems on a single website. The “Com-mercial” version is conceived as a professional plat-form. It provides, for example, an invoicing module for automatic billing as well as a project administra-tion system with all relevant data. Finally, the “Serv-er Edition” is a solution for operators and investors who monitor installations ranging in number from 500 to well in excess of 1,000 systems.

As German Intego GmbH from Erlangen emphasizes, microcrack detection is an important tool for wafer, cell and module production. The company introduces the Taurus Cell system for automatic detection of cracks in single wafers and cells. A similar technol-ogy, working on stacks of wafers and cells, has al-ready been shown at the Photovoltaic Technology Show in April this year. According to the producer, Taurus Cell works contact-free and generates images of cells which are suitable for automatic error detec-tion. Thus, results are not disturbed by metallization and the natural grain structure. They can be present-ed on an operator monitor, where the user can change system parameters such as minimal error size, super-vise inspection results, and handle external signals.

The Swiss mechanical engineering company Essemtec launches a new 3D-measuring instrument named Traqu on the market. The instrument uses an infrared interferometer to create a digital 3D model of objects, accurate to the nanometre. Essemtec state that it al-lows for any kind of measurement to be taken at a lat-er time: of volume, depth, height, extension or rough-ness, both of reflecting and matt surfaces. Thus, com-ponents can be checked for their compliance with specifications by performing measurements on the digitised model, regardless of where the original model is, also after processing or delivery to the cus-tomers. Users are free to define the measurement, what to measure and can for example calculate the volume, determine distances or calculate the rough-ness of a surface. According to the manufacturer, the instrument can also determine layer thickness be-cause the function of the interferometer is similar to that of an ultrasound probe. According to Essemtec, details down to the nanometre range can be re-solved.

Traqu is capable of capturing up to 1 million im-ages per second. The 3D scanner can digitise areas of up to 400 mm x 300 mm. The manufacturer can opti-mise and modify the instrument for specific purposes .

The SolarModule EL-QuickCheck is an alternative for making the first step into the electroluminescence technology and whenever a very quick inspection feedback is required.

mbj-Solutions will also introduce a fully auto-matic, high resolution electroluminescence inspec-tion solution for pre-laminated solar modules. The system has an automatic contacting unit to apply power to the module. According to the company, the

new image processing software detects the process relevant defects fully automatically. Using electrolu-minescence before lamination allows finding critical defects at a process stage where the product can still be repaired. This should lead to an overall improved quality and to a higher yield at the end of the day. Both the SolarModule EL-QuickCheck and the Solar-Module EL-Inline will be shown in Valencia for the first time .

Ulvac presents the “MPEC-opt1300,” a local efficien-cy and haze measurement system for use on tandem type thin-film solar cells. In contrast to common man-ual measurement, the MPEC-opt1300 system uses a newly developed mini-cell forming function (patent-ed) with a laser, to form mini-cells without cutting the substrate and evaluate the efficiency distribution. With recipe settings, the system can automatically perform everything from mini-cell formation to distri-bution measurement and mapping display. The eval-uation of 7 points on the substrate by the convention-al manual method could take more than an hour, the system can shorten this to 8 minutes. Besides mini-cell formation and local efficiency measurement func-tions, the system is equipped with a haze measure-ment function and shunt resistance measurement function. It is also capable of measuring and evaluat-ing entire substrate surfaces of 1,100 mm × 1,400 mm in size.

The Swiss Sputnik Engineering AG will present their new three-phase string inverters in Valencia. The new MT (multi-tracking) series complements the Sputnik range with three performance classes between 10 and 15 kW. The maximum input voltage of the de vices is 900 V. During their development, the Sputnik engi-neers focussed especially on the cooling concept. Now the devices can perform at their maximum level up to ambient temperatures of 50 °C. The protection class IP54 allows for indoor and outdoor installation while the devices achieve 97.5 % in the European ef-ficiency rating.

Of course there will also be the new TS series, launched in March, to be seen in Valencia. The de-vices are available with rated outputs between 50 and 300 kW.

The Austrian company Fronius will mainly concen-trate on the new central inverters series Fronius CL at the EU PVSEC. The launch took place in June 2010, since then the product has been sold almost world-wide. The new CL profits from a new modular system structure: “Up to 15 identical power units are switched on and off depending on the intensity of so-lar irradiation and based on operating hours. This op-timises the load and provides, especially in the par-tial load range, for maximum yields of the PV sys-tem,” says Christoph Panhuber, Divisional Manager of Fronius Solar Electronics. In the case of a faulty power unit, there is little yield loss because another power unit will take its place.

In the performance classes 36, 48 and 60 kW, the Fronius CL is suitable for PV systems of up to several hundred kilowatts.

Voltwerk electronics GmbH from Hamburg are on show at the European Photovoltaic Solar Energy Ex-hibition and Conference for the third time now. A heavily dis-cussed topic this summer in Germany was the storage of PV electricity to increase the share of own consumption. Voltwerk have their system solution VS 5 hybrid packed and ready. The VS 5 hybrid is a combina-tion of a 5 kW transformerless inverter, a lithium-ion battery with a capacity of 5 kWh and a management system with a colour touch screen. The bat-tery capacity can be upgraded as required – the system cabi-net is designed for up to 8 kWh.

The energy is either fed di-rectly from the PV system into the electricity grid, taken from storage or made available si-multaneously from both sourc-es.

If the amount of energy made available from these sources is insufficient, AC mains power will be used. According to Voltwerk, the VS 5 hybrid system could see the coincidence in time of photovoltaic electricity generation and its usage in a 4-person household increase from 30 % to about 70 % compared to a conventional PV system. During the summer months, a 100 % independence from the public electricity grid could be achieved. The VS 5 hy-brid is to hit the market in the first half of 2011.

Voltwerk will also be presenting their string in-verter series VS in Valencia, which has already re-ceived the “red dot award” for design. In the area of large-scale systems, the Hamburg company will talk about the new central inverter station. The complete-ly pre-installed station is available in the perform-ance classes 400 to 1,200 kW.

The Swiss manufacturer of sine wave inverters Studer Innotec has introduced a new range of inverter-chargers for solar and hy-drid systems. Consisting of three products (1 kW/12 V, 1.2 kW/24 V, 1.4 kW/48 V) the new XTS inverter-chargers pro-vide system integrators and project operators with a power range that comple-ments the existing Xtender range and therefore enlarg-ing the product family to 13 in-verter-chargers, available in 230 VAC and 120 VAC. With IP 54, the new inverter-charg-ers are equipped for tough en-vironment. By the implementa-tion of several units, it is pos-sible to create a 3-phase pow-er system and/or to set them in parallel to increase the pow-er available. By means of an aux-iliary relay module, two potential free contacts can be programmed to provide many supplementary functions like the automatic start of a genset, the load shedding, the alarm signal, conditional charge of the battery etc. The optional remote control memorizes and dis-plays the events that occurred on an installation. It gives access to the adjustable parameters of the XTS like the setting of the charge curve of the battery, the programming of the auxiliary relays or even, among others, to a lot of operation options. A slot is availa-ble for a SD card which will allow the parameters memorizing, the data transfer or the software update. Like with all Xtender models, it is possible to set a battery voltage above which the solar energy will be used in priority over the AC source (grid, genset).

In Valencia, the German module manufacturer and developer Solon SE will present their “Solon Velocity” system, which allows for faster planning and con-struction of large photovoltaic power plants. Yield calculation is not only supposed to be easier but also more precise.

To date, every photo-voltaic power plant is in-dividually planned on the drawing board. The Velocity concept entails that one PV plant consists of 1 MW clusters. These are built from components that have been standard-ised and tested as to their interaction. Each cluster consists of the mounting frame, either fixed or single-axis tracked, the modules (of course from Solon), inverters, cables and the remote control and monitoring tool Solon Scada. The latter transmits system data via the Inter-net, allowing the operator to monitor the system and intervene online if required. Solon also offer plant maintenance services. The Velocity system is now available worldwide.

There are new mounting systems from Mounting Systems GmbH from Germany to be seen. Mounting Systems have given their ground-mounting system Sigma a new mounting rail. Its shape is reminiscent of the Greek letter Pi (π) – so it’s called the Pi-rail. These profiles are known from the classical structur-al engineering of large house and hall roofs. The ben-efits: less material usage and lower costs while main-taining higher stability and a larger span. The solar modules – whether framed or laminated – can be easily snapped into the Pi-rail without having to drill or use screws. To achieve this, Mounting Systems designed a specifically shaped adapter. Mounting Systems have filed a patent application for their Pi-rail. The other features of the Sigma system remain unchanged. It is mounted on pile-driven foundations and can compensate up to 10° differences in height in the terrain due to its flexible base rails and the height-adjustable adapter.
