The PV market has an average annual growth rate of 9-22%
In 2015 the thin film part of the PV market will be appr. 10 % (~8 GW annual demand)
After the temporary consolidation phase in 2011 – 2014 further and even stronger growth is expected
Grid parity will be achieved in 2013 – 2016 depending on location, this will give an additional boost of PV increase

BIPV’s strong growth rate of appr. 50% per year yields to 1.9 GW by 2015. Predicted growth up to 2,25GW in 2017 Thin film technology is well suited for BIPV because of
technical advantages (e.g. appearance) Flexible TF is even more superior for BIPV due to:
Any size, any shape, any voltage Light weight products can be applied

High solar cell efficiency enables further cost reduction
• Cost reduction by efficiency increase (€/Wp)
• CIGS technology has highest theoretical
efficiency potential among all mainstream
thin- film technologies
• CIGS technology will close the gap with c-Si as
technology matures in coming years
• CIGS on polymer has proved the potential to
match the efficiency of CIGS on glass
• Existing lab record of CIGS on polymer is already
higher than record of other main thin-film
technologies CdTe, a-Si, and currently poly-Si

Corporate Overview.
Our Proprietary Technology
Solarion develops and produces thin-film solar cells and modules employing a patented ion beam-assisted manufacturing process that deposits a thin layer of copper indium gallium selenide (CIGS) on the lightest substrate available at reduced deposition temperature.
Current Solarion employees app. 130 in three locations.
HQ Leipzig cell R&D, Zwenkau 20MW mass production, Dresden module R&D
Zwenkau facility, Mass-production 20 MW
1996 2002 2004 - 2007 2007 - 2008 2013
Idea of flexible CIGS manufacturing technology was born at IOM institution
Solarion was founded as a spin-off from IOM e.V.

• c-Si Solar module requires mounting system installed on the roof and the cabling is on top of the roof.
• Solarion integrated solution is the roof • No mounting system required, cabling protected by
roof. • No additional cost for PV installation
Up to 35% BOS cost savings: Material savings (no
back-sheet, no mounting system), no additional labor cost
Solarion flexible module offers substantial savings on BoS costs through roof-integrated PV solutions.
