Potential of further cost reduction

Cost reduction by scaling the capacity

Requirement for future competition and success:

Capability of product flexibility

Cell efficiency


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.

Launch of active business operation

Pilot Phase: Development and optimization of processes for small scale production and intense R&D activities.

Conclusion of pilot phase and intensified risk analysis on transition into mass production: full running roll-to- roll pilot line.

Start ramp up for roof shingle manufacturing line (10MW)

• 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.
