CHALCOPYRITE-PEROVSKITE PN-JUNCTION THIN-FILM PHOTOVOLTAIC DEVICE

摘要

A thin-film photovoltaic device includes: a substrate for supporting the thin-film photovoltaic device; a back contact layer disposed on the substrate; a p-type solar absorber layer disposed on the back contact layer, the p-type solar absorber layer including one of a Group IB-IIIA-VIA.sub.2 material and a IIB-VIA material; an n-type solar absorber layer disposed on and in contact with the p-type solar absorber layer, the n-type solar absorber layer including one of a Group IA-IVA-VIIA.sub.3 material, a Group IA.sub.2.-IVA-VIIA.sub.6, and a Group I.sub.2.-I-IIIA-VIIA.sub.6 material; and a semi-transparent top contact layer disposed on the n-type solar absorber layer.
