Thin film n-CdS/p-CdTe solar cells were prepared from chemical bath deposited CdS and electrodeposited CdTe layers. The microstructural and some electrical properties of these layers were studied and connection with photovoltaic performance of the cells was shown. Especially, adherence of the CdS films and the quality of heterojunction interface manifesting themselves in the value of the open-circuit voltage
U
oc depend on the cadmium precursor used for CdS deposition and on whether pH buffered conditions were applied or not. The number of CdS layers in the cells needed to obtain
U
oc of about 700
mV is connected with the CdS deposition conditions.
