Abstract
CdTe solar cells with ZnS window layer deposited by ultrasonic spray pyrolysis (USP) were grown. The current density of such solar cells reached 24.7 mA/cm2 without anti reflection coating (Voc 594 mV, FF 64.2%, η 9.4%). For CdTe solar cells with CdS and ZnS window layers we quantified the Jsc loss mechanisms in detail. In order to tune the conduction band alignment, and increase the Voc, ZnO1−xSx grown by atomic layer deposition (ALD) was used.
