Photoelectrochemical studies on colloidal cadmium sulfide containing cadmium selenide electrodeposits

Colloidal cadmium sulfide containing cadmium selenide films were prepared by electrochemical codeposition to explore possibilities of obtaining enhanced photoresponsivenesss and increased resistance toward electrochemical corrosion. Inclusion of colloidal particles was inferred on the basis of current-voltage and photoaction spectral studies. Tafel plots were constructed for examination of corrosion behavior of the electrodeposits. The results show that colloidal cadmium sulfide inclusion improves photoactivity and electrochemical corrosion of the electrodeposited cadmium selenide in a significant measure.
