| Abstract: | Cd1–xZnxTe films were deposited by simultaneous evaporation of CdTe and ZnTe. These Cd1–xZnxTe films were of cubic phase, and strongly (1 1 1) oriented as deposited. Predominant direct optical transitions were observed and the band gap varied with zinc content in a non-linear way. A structure development of CdS/CdTe/ZnTe : Cu solar cells with a Cd1–xZnxTe buffer layer was proposed. |
