High efficiency thin-film solar cells

Materials Colloquium 2020 - April, 1st, 16:30


Yaroslav Romanyuk (EMPA Dübendorf)

Thin-film solar cells belong to the so-called second generation of solar cells, whereby a thin semiconductor absorber layer of 1…5 microns is used to fully absorb incoming sunlight. The talk will describe current status and research challenges for three thin-film technologies based on Cu(InGa)Se2, CdTe and organometal lead halide perovskites, which have demonstrated power conversion efficiencies in the 22-25% range. All technologies are being actively investigated at the Laboratory for Thin Films and Photovoltaics at Empa: https://www.empa.ch/web/s207
