Abstract
Composition of zinc and cadmium have been measured for three key regions related to the formation of Cu2S on ZnxCd1−xX by aqueous ion exchange. These are the ion‐exchange solution, the resulting Cu2S, and the ZnxCd1−xS near the Cu2S‐ZnxCd1−x interface. It is found that the participation of zinc in the ion‐exchange reaction is incomplete. Zinc is thus retained in the p‐n junction region, and is found mainly in the ZnxCd1−xS just under the interface. This phenomenon helps to account for certain differences between electro‐optical properties of Cu2S/CdS and Cu2S/ZnxCd1−xS solar cells.Keywords
