摘要
The heavily doped tellurium (Te) -rich layer is an effective back contact material by chemical etching CdTe traditionally. But the reported studies drew the conflicting conclusions concerning the physical mechanisms about Te layer in CdTe. In this paper an evaporated Te layer based on a CuCl2 treated CdTe surface was developed for application in CdS/CdT(1)e solar cells, and the effects of the evaporated Te buffer on the device performance were evaluated in detail. It is found that the effects of Te layer on the device performance depend on the CdTe surface. As a result, an open circuit voltage up to 825mV and filling factor up to 70% was obtained for the devices with an evaporated Te buffer after CuCl2 treatment.
