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