Cu(In,Ga)(S,Se) (CIGSSe) solar cells buffered with zinc oxysulfide (Zn(O,S)) have reached record cell efficiencies of 22.3%. However, the key limitation of Zn(O,S) buffered CIGSSe solar cells comes from its requirement of an extra light soaking step during fabrication, as opposed by conventional Cu(...
