Impact of the structure of Mo(S,Se)2interfacial region in electrodeposited Cu…

In this study, we investigate the formation of Mo(S,Se)2 layers in the interface region between the absorber and the back contact in electrodeposited CuIn(S,Se)2 (CISSe) solar cells, and its influence on the resulting devices. Mo(S,Se)2 layers are formed spontaneously in the Mo/CI(S,Se) interface during the annealing of the absorber, but have a serious impact on the solar cell performance, bein…
