CuInSe2 films of various stoichiometries have been prepared by the two-stage process. In this method, Cu-In layers were first evaporated onto Mo-coated glass substrates in the form of stacks, and then they were selenized in a H2Se atmosphere at 400 °C to form the compound. CdZnS/CuInSe2 heterojunction solar cells were fabricated on these films and conversion efficiencies close to 7% were obtained.
