The properties of polycrystalline, thin film CuInSe2/CdS and CuInSe2/Zn/sub metallized alumina substrates are described. The mixed sulfuide cells are described as exhibiting increased open circuit voltages, slightly higher short circuit currents, and improved efficiencies. Mixed sulfide film preparation by evaporation of CdS and ZnS powders from a single source and from two sources is discussed with preference given to the later technique. Selenide film preparation in a planetary or rotating substrate vacuum deposition apparatus is described. A 1 cm(2) area cell without AR-coating produced by the planetary approach demonstrates a 7.5% efficiency. The results of cell heat treatment studies which show a strong environmental dependence are presented and indicate the desirability of an oxygen containing atmosphere. An automatic, computer controlled, cell-measurement system for I-V, C-V, and spectral response analysis is described. The results of the cell analysis and cell modeling studies on both the plain CdS and mixed Zn/sub x/Cd/sub 1-x/S thin-film devices are presented.
