Abstract

Electrochemical deposition and characterization of CdSeTe thin film has been presented in this work. CdSe x Te 1− x (0 < x < 1) compound thin films have been electrodeposited cathodically on SnO 2 conducting glass slides using various pH values and deposition potentials using an electrolyte bath solution consisting of CdSO 4, SeO 2 and TeO 2 at different temperatures. The composition in the films has been found to vary linearly with the composition in the bath solution. The increase of selenium content ‘ x’ in the CdSe x Te 1− x films has increased the band gap of the film. Photoelectrochemical solar cell studies were done and its response with concentration of Se was studied and these results have been discussed in this report.
