Abstract

In this paper we present a study of the influence of substrate temperature, RF power, target erosion, and magnetic field configuration on RF sputtering of CdTe and CdS. These sputtering parameters are shown to affect deposition rate, film morphology, photoluminescence efficiency, and cell performance. The magnetic field shape and strength affects the charged particle flux on the growing film and appears to have a strong influence on the final cell performance
