Band discontinuity and bulk vs. interface recombination in CdS/CuInSe/sub 2/ solar cells
A numerical model which shows the effects of conduction band discontinuity, Delta /sub cb/, in CdS/CuInSe/sub 2/ solar cells is presented. Two scenarios for the dominant mechanism controlling open-circuit voltage, V/sub oc/, are considered: CuInSe/sub 2/ bulk recombination and CdS/CuInSe/sub 2/ interface recombination. The computation shows that the short-circuit current is independent of Delta /sub cb/ for either scenario, while V/sub oc/ is strongly affected only for the interface-dominated case and only for the CuInSe/sub 2/ conduction band positive with respect to the CdS conduction band. The experimental evidence implies that interface domination is not always the case in real devices, if it occurs at all.<>
