Abstract

Devices of ITO/CdS/CdTe/Te/Al were prepared by Electron-Beam deposition under a vacuum of $7{\times}10^{-6}$[torr]. Optical, Electrical, Structural and Photovoltaic properties of thin film CdS/CdTe at substrate. temperature 300~500[$^{\circ}C$] were also investigated, The structure of CdTe films deposited was of the zincblende type a preferential orientation of the (111) plane parallel to the substrate, the CdTe dark resistivity was about $10^6[{\Omega}cm]$. The conversion, efficiency of the cell increased with increasing substrate temperature. The best-fabricated Cell was a conversion efficiency of 9.1[%].
