Abstract:
A photovoltaic device includes an electron blocking layer (EBL) and an absorber layer. The EBL is positioned between the absorber layer and a back contact layer. A material of the EBL is a cadmium zinc telluride Cd(1-y)Zn(y)Te, and a material of the absorber layer is a cadmium telluride selenide CdTe(1-x)Se(x) producing a lattice mismatch between the materials of the EBL and between the materials of the absorber of less than about two tenths of a percent when x˜y and has a value less than about 0.4.
