Abstract

Cd_1-xZn_xTe thin films of different zinc concentrations were prepared using simple and cost effective electrodeposition technique. The films were coated on FTO substrates using a chemical bath consisting of CdSO₄, ZnSO₄ and TeO₂. In this deposition of Cd_1-xZn_xTe thin films electrodeposition potential, bath temperature, precursor concentrations and pH were optimized. The morphological, structural and optical characterizations of the films deposited with various zinc compositions are also reported. The grown films displayed a high-quality polycrystalline films with crystallites orientation along (1 1 1) direction. The deposited Cd_1-xZn_xTe alloy films showed direct band gaps varying between 1.67 and 2.15 eV depending upon zinc concentration. Photo electrochemical (PEC) solar cells fabricated using the grown alloy films of different zinc concentration showed increased efficiency for the increase of zinc concentration.
