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

This paper reports the first study of the photoelectric properties of a double heterojunction cascade solar power converter based on the ternary compounds CuInSe2, AgInSe2, and CdS. We evaluate the photoelectric parameters of individual elements and a double-heterojunction converter. The efficiency of the cascade converter is eta = 10.7%.
