A series of photovoltaic heterojunctions of the type n-Zn0.1Cd0.9S/p-CdTe have been prepared by spray pyrolysis of ZnCdS films on single-crystal CdTe with variation of the CdTe substrate temperature and of the postdeposition heat-treatment temperature in hydrogen. Open-circuit voltages as high as 0.82 V are observed compared to maximum values of 0.74 V observed for n-CdS/p-CdTe junctions also prepared by spray pyrolysis. Cell efficiencies are in the 6–8% range without correction for reflection losses.
