Paper Abstract

This paper embodies the first report on the pulse reversal deposition of CdSe thin films. The as-deposited and heat treated films were characterized by XRD, optical absorption spectroscopy and electrical properties. The polycrystalline deposits of CdSe obtained indicated a hexagonal structure after heat treatment at 550°C. From the otpical absorption studies the bandgap was found to be 1.70 eV and absorption co-efficient of 104 cm-1 were obtained. At an illumination of 80 mWcm-2 conversion efficiencies of 5.56% and 6.74% were obtained for the photoelectrodes without and with pulse reversal.
