One of the relevant technologies for thin-film photovoltaics is based on chalcopyrite absorber materials. Following the chemical composition of the most frequently used chalcoyprites, i.e., Cu(In,Ga)Se2 and Cu(In,Ga)(S,Se)2, these materials are also known as CIGS. The advantages of CIGS in terms of production and applications are summarized in the CIGS White Paper

The CIGS groups at PVcomB are developing processes for high efficiency and low production costs. We assist our industrial partners in bringing new developments from the laboratory closer to industrial production. A complete range of industry standard processes are available for the preparation of cells and modules. We share many of the standard characterization tools with the other groups at PVcomB, have access to sophisticated analysis tools elsewhere at the HZB, but also operate a dedicated preparation/surface analysis cluster tool.
