The institute silicon photovoltaic operates three technology platforms for fabrication of solar cells based on monocrystalline silicon, poly-crystalline silicon on glass as well as pervoskites. These platforms form the basis for research on innovative tandem-cells and hetero-junction or hybride- devices. For  particle free processes, two cleanroom laboratories ( 12.8 and EMIL) are available.

Silicon heterojunction solar cells on wafers

The institute operates a complete research line for the fabrication of c-Si/a-Si:H heteojunction solar cells on wafers up to 6 inch. The line is comprised of the following tools:

In addition, an UHV deposition tool can be used for special deposition and characterization tasks.

Polysilicon solar cells and mini modules on glass

FrontERA cells

For the fabrication of liquid phase crystallized silicon thin-film solar cells and modules on glass. The following tools are availabe

Perovskite solar cells


The institute operates three gloveboxes for synthesis and characterization of perovkite solar cells. Research is conducted in close collaboration with the Young Investigator Group Perowskite Tandem Solar Cells and the HySPRINT Innovation Lab.
