Defect spectroscopy on Cu(In,Ga)(S,Se) 2 -based heterojunction solar cells: role of the damp-heat treatment
… characteristics induced by accelerated lifetime tests on solar cells of the heterostructure ZnO/CdS/Cu(In,Ga)(S,Se)2/Mo are investigated. The fill factor and open-circuit voltage of non-encapsulated test cells are reduced after prolonged damp-heat treatment in the laboratory, leading to a reduced …
