Abstract

Type conversion in CdS in CdTe/CdS solar cells was disproved. CdS and high-resistance SnO2 layer in USF cells were found to be electronically similar, rationalizing the need for a HR layer in cells with very thin CdS for supporting the junction photovoltage, without reducing the cell's blue response. Most importantly, combined XS SCM and SKPM of CdTe/CdS cells show that the photovoltaic and metallurgical functions coincide.
