Record for perovskite/CIGS tandem solar module

Thin-film technologies can dramatically reduce the cost of next-generation solar modules. Whereas their production cost is low, it is in particular the combination of complementary absorber materials in a tandem solar module that increases the power conversion efficiency. At the PSCO international conference in Genova, researchers from KIT, ZSW, and the Belgian research institute imec present a perovskite/CIGS tandem thin-film solar module that achieves 17.8 percent in efficiency, surpassing for
