Fabrication and properties of CuInSe2/AgInSe2/CdS double heterojunction cascade solar cells

Abstract

This paper reports the first study of the photoelectric properties of a double heterojunction cascade solar power converter based on the ternary compounds CuInSe 2 , AgInSe 2 , and CdS. We evaluate the photoelectric parameters of individual elements and a double-heterojunction converter. The efficiency of the cascade converter is η = 10.7%.
