● Synopsis of research (references in brackets refer to above listed journal papers) Solar energy system analysis

Doctoral research during the years 1981-85 focused primarily on the analysis of the long-term performance of solar energy systems, including passively solar heated buildings and active solar collector systems for industrial hot water applications [2, 3, 5, 6, and 11]. Rather than employing detailed computer simulations, which need hourly meteorological data that are often not available, analytical models requiring only average monthly meteorological data were successfully employed.

Building energy diagnostics Postdoctoral studies at Princeton University related to the field of energy in buildings. Collaborations at Princeton resulted in studies of in-situ measurements for diagnostics of building energy systems such as the measurement of heat transfer coefficients of building envelopes [8, 9] and the non-intrusive flow measurement [16] in water distribution pipes. The flow measurement is based on cross-correlation of space-separated temperature signals on the pipe’s surface avoiding the need of intrusive installation of flow-meters. Accuracies of 10% were achieved. A study of room air-conditioner usage showed how summer peak loads (a major concern to the utility companies) are created [13]. Analysis of experimental data highlighted the effect of human behavior on the development of peak power demand. As power demand grows with ambient temperatures, residents in residential buildings exacerbate the increase in demand due to the different thresholds (or thermostat settings) individual tenants preferred. This range was found to be from 24 to 28ºC, resulting in a significant fraction of installed power producing capacity being used very infrequently with implications on the return on its investment.

Solar radiation and enclosures For the performance prediction of solar energy systems, much effort is invested in obtaining reliable solar radiation data, with direct beam radiation being one of the more difficult data set to record reliably. A multi-pyranometer [14, 18] was devised that produces global, diffuse and direct beam radiation without moving parts within reasonable accuracies. Related to this, new calibration methods were studied [17, 19]. Over extended periods (months), we could show that relative calibrations, based on normal incidence measurements, could be provided at substantially higher accuracy and more reliably than with conventional horizontal setups. The interdisciplinary nature of the Jacob Blaustein Institute encouraged collaboration with other groups such as the Closed System Agriculture group that investigated a new type of greenhouse. Crop yield in greenhouses can be increased by fertilizing the plants with carbon dioxide. Quadrupling the carbon dioxide concentration in the greenhouse atmosphere (compared to ambient air) can increase crop yield by 30 to 150%. The input of CO2 is only possible when the greenhouse is closed, a requirement which is difficult to achieve without it overheating, particularly in summer. Shading is insufficient and reduces the level of light available for plant growth. The innovation here was the removal of by the plant unutilized near infrared solar radiation by means of a liquid radiation filter (LRF) [21]. The LRF flows in a double-layered roof of the greenhouse and acts like a solar collector. The collected heat can be stored and redirected at night back to the greenhouse when heating is required or simply rejected to ambient air via a cooling tower. A simulation was developed to predict the performance of the LRF Greenhouse for studying both the short-term (hourly) and long-term performance, indicating the number of hours per day the greenhouse could be maintained closed and fertilized with CO2. A comparatively simple model without adjustable parameters, based on the main physical phenomena occurring in the greenhouse, sufficed to predict the greenhouse performance with very good accuracy [21, 27]. This research found a natural continuation in a fruitful collaboration with a European consortium of universities and industries in Italy [Greenhouse Integrated System, please see under grants 2001-2003].


Radiative transfer of energy Non-imaging optics The involvement in the field of non-imaging optics came about when researching concentration of solar radiation, either for achieving high temperature or for reducing absorber area, in particular for photovoltaic systems. Rather than maintaining an image as conventional lenses and mirrors do, non-imaging optics destroys the image of the radiation source in favor of reaching higher concentration. This field of optics, started in the 1960s, has many applications beyond the field of solar energy. Research in this area resulted in a number of advances: remote irradiation of a target with a fiber [22, 31], a general analysis of maximum power remote irradiation [23] (which resulted in a patent), and methods for designing non-imaging concentrators and illuminators for a large range of absorber shapes [25]. The latter work shows a simple way to predict an upper bound of the performance of axi-symmetric concentrators based on two-dimensional edge-ray designs when target and source have different shapes (giving rise to a loss due to skewness mismatch). Fiber optics Research in this field has found applications in medical optics, such as in ‘solar surgery’ [26] – a notion that quickly captured the imagination of the scientific community and the media with reports appearing on CNN, in New Scientist, Physics Today, among others, and in all the major Israeli newspapers. The method of concentrating sunlight 10,000-fold and transporting it through fibers has been suggested for the large-scale collection of solar radiation [29]. Of particular interest here is the performance of optical fibers used for transporting concentrated sunlight. It appears that light leakage from such fibers had not fully been appreciated by producers, nor had it been researched in great detail. We developed analytical models describing the leakage that was observed experimentally [33]. Though technically feasible [34], the high costs of quality fibers, capable of transmitting the broad spectrum of sunlight without large losses, prohibits the deployment in power production applications; however, for niche applications such as fiber-optic surgery, or characterization of photovoltaic cells, discussed further below, incoherent light transport in fibers is of significantly practical value. ‘Solar surgery’ attracted private research funds and has been realized experimentally [35, 36]. A prototype has been built and clinical trials on live rats have been shown to successfully imitate laser surgery at potentially much lower costs. This work, performed in collaboration with a medical team from Soroka Hospital, Beer Sheva, was published in “Nature” [37], triggering once more high interest from both scientists and the media. Concentrators for Photovoltaics At the turn of the millennium, the parallel development of high fuel prices and high efficiency solar cells re-ignited the interest in power production via concentrating photovoltaic (CPV) systems. Miniaturization of the solar collection units permits low-cost mass-production of optics with significant advantages in passive heat rejection, receiver positioning, and support structures [32]. With the development of solar cells capable of operating under a thousand-fold concentrated sunlight, the mini-dish approach [32] presents a particularly well-suited option in that its smallness permits passively cooled cells, avoiding expensive active cooling systems, common to centralized power generation, with its parasitic power needs and delicate controls (a failure to cool leads to the destruction of the cells). An experimental realization exploring this option was funded by the US Department of Energy [43], and commercial interest let to the development of practical constraint-driven solutions to CPV systems. To wit, we developed several devices for SolFocus Inc., which patented systems have been installed, are operating at specifications, and are in production at a level of tens of megawatts [41, 56, and 59]. These designs employ dual mirrors based on aplanatic optics, originally used in microscope and telescope designs with very low radiation collection efficiency (image fidelity being of paramount importance there). It is apparently the first time that such optics have been analyzed for and used in high-efficiency, high-concentration of radiation near the thermodynamic limit.

CV Daniel Feuermann page 24 Near-field aplanatic optics An outgrowth of solar fiber-optic surgery was the use of Xenon-arc discharge lamps instead of the sun as a light source. Coupling the intense plasma discharge region of the lamp into a fiber required a new kind of near-field optic that was invented, using aplanatic designs [45, 46, 47]. With the Soroka hospital medical team, the feasibility of the method was demonstrated [51]. Methods to study the non-uniform plasma region of the lamp were also developed [54], and we studied theoretically and experimentally the possibility of ‘recycling’ light to enhance collection efficiency from the plasma region of the lamp [53]. A second, different, type of near-field optic was designed for a high-intensity reactor produced with a plasma-arc discharge lamp [57] for the production of inorganic fullerenes. This reactor serves as an alternative to the solar-driven photo-thermal synthesis of inorganic nano-materials (described further below). Characterization of photovoltaic cells Optics, tracking and alignment in a photovoltaic module comprised of multiple concentrator units cause non-uniform illumination of the cells. Experimental techniques developed using above mentioned fiber-optic mini-dishes (concentrating sunlight up to 10,000 times outside the laboratory into a fiber and then into the lab) permitted probing of the cells under varying intensities and flux distributions in a controlled indoor environment. The work resulted in the discovery of hitherto unrecognized phenomena [38, 42, 44, 49], such as the capability of the latest concentrator cells to maintain their high efficiency at high concentration ratios, even at highly non-uniform illumination. This recognition affected the design of new optics for CPV where the emphasis could now be placed on small accurate optics that produces a focus tighter than the size of the cell, and, in return, permitting lax tracking tolerances [56]. This is of immense practical importance for the manufacturers in their effort to reduce tracking, alignment, module stiffness, and support structure costs. Ultra-high irradiance furnace Another application of the fiber-optic mini-dish scheme permitted the study of synthesizing inorganic fullerenes at very high temperatures, in collaboration with the Weizmann Institute, funded by the Ministry of Science. The precursor material is irradiated with intense radiation emerging from the tip of the fiber (using a similar system to that for studying solar cells). We were able to produce the high temperatures, in excess of 2000ºK, necessary to enable the formation of novel inorganic fullerenes such as Cs2O nanoparticles [50], singular MoS2, SiO2 and Si nanostructures [55], and WS2 and MoS2 fullerene-like nanoparticles [58]. The fiber-based system, though achieving solar concentration ratios of 10,000, is limited in power. Further, radiation diverges at the fiber tip and limits the intensity achievable at the precurser material. In response, a solar furnace was designed and constructed, increasing the total available power by an order of magnitude while using converging optics with which concentrations of 20,000 suns were achieved. The converging rays permit higher intensities on the target (located behind the quartz glass of ampoules containing the precursor material). This research is in progress and has already produced higher yield of novel materials which are in the process of being analyzed. In addition, the furnace also permits the study of larger, up to 100mm2, solar cells at high concentration; something that was not possible with the low power of the fiber-optic mini-dish. In connection with the solar furnace, a unique flash, solar-based, ‘simulator’ has been designed and constructed to enable the study of solar cells under extreme flux levels. It permits the irradiation of the cells for periods of milli-seconds, short enough to prevent significant heating, but long enough to measure the current-voltage behavior of the cells, an important metric for characterizing them. The advantage over standard lamp-based solar simulators is (i) the capability of measuring at extreme flux levels and (ii) having a nearly perfect solar spectrum, something that is difficult to achieve with artificial light, but important for the spectrally sensitive solar cells. Research will continue in the forseeable future in these two directions: solar-based photo-thermal synthesis of inorganic fullerenes, and the study of high-concentration, high-efficient solar cells.
