Abstract

Copper sulfide (CuxS) films were studied as a back contact material for CdTe solar cells. The CuxS films were made by chemical bath deposition in aqueous solution. Annealing at 200° C in Ar improved the performance of the solar cells. Using the CdS/CdTe/CuxS/C structure, an open-circuit voltage (Voc) higher than 840 mV and an energy conversion efficiency higher than 11% were obtained.
