Abstract

Composition, optical properties, structure properties, and surface morphology of thin films of Cd1-xZnxS (x ≤ 10%) prepared by chemical bath deposition (CBD) are reported. The best cell efficiency was 15.7%. It used a Cd1-xZnxS window layer, was confirmed by NREL (Voc = 840.1 mV, Jsc = 24.81 mA/cm2, and FF = 75.55%), and had a CTO/ZTO/Cd0.92Zn 0.08S/CdTe cell structure. The use of low zinc concentration in the Cd1-xZnxS layer and interdiffusion between Cd 1-xZnxS and CdTe layers were assumed to be the reasons for maintaining high Voc and FF.
