Impact of capping during the formation of Cu2ZnSn(S,Se)4 thin films

Materials Science in Semiconductor Processing, 2016
Abstract Major challenge for the fabrication of kesterite absorber thin films such as CZTSSe (Cu2ZnSn(S,Se)4) is the volatility of chalcogens. Material loss and poor morphology are two key issues during high temperature annealing, carried out for the formation of CZTSSe thin film absorber layers. The purpose of the present study is to investigate the

Tailoring Mo(S,Se)2 structure for high efficient Cu2ZnSn(S,Se)4 solar cells

Solar Energy Materials and Solar Cells, 2018
Abstract The direction of Se-Mo-Se sheets to the Mo film is crucial for the thickness of Mo(S,Se)2 and the electrical conductivity, so as the back contact of Cu2ZnSn(S,Se)4 solar cells. In this study, the preferred orientation of Mo(S,Se)2 film changes from (100) peak to (103) peak, i.e.
