文摘

Cadmium free buffer ZnS layers were successfully deposited onto CZTSSe absorbers by chemical bath deposition. CZTSSe solar cell with photo conversion efficiency η = 3.8% was achieved with Se rich absorber. Increasing ZnS buffer layer thickness the solar cells showed poor performances. Optimum thickness of buffer layer is found to be 56 nm to obtain better photo conversion efficiencies.
