CdTe thin film solar cell on flexible metallic substrate

Abstract

In this paper lightweight and flexible CdS/CdTe thin film solar cells on metallic substrates have been developed using a close spaced sublimation process with a low deposition temperature. The analysis of basic properties of CdS and CdTe thin films was carried out by SEM and XRD characterization techniques. The thin film solar cell devices were characterized by current- voltage and photocurrent techniques. Open circuit voltage (Voc) of 710 mV, short-circuit current density (Jsc) of 20.55 mA/cm² and conversion efficiency of 9.04% was obtained for the flexible CdTe/CdS thin film solar cell under AM1.5 illumination.
