The tandem solar cell developed within the scope of project CAPITANO combine a perovskite top solar cell with a CIGS bottom solar cell. Both technologies can be manufactured as thin-film technologies on square metre-sized substrates, promising low cost production. KIT's role will be developing new materials and processes for the production of perovskite solar cells and modules and investigating scalable manufacturing techniques. The institute particularly focuses on solution processing and vacuum-based deposition methods. KIT will also develop a light management concept for the modules and take responsibility for yield calculations.
