Photoelectrochemical studies on galvanostatically formed cadmium selenide films using mixed solvents

Galvanostatic deposition technique has been used for the formation of cadmium selenide films using water and dimethyl sulphoxide mixtures of variable composition. For photoelectrochemical characterization of these electrodeposits, photoelectroconvertibility and photoaction spectral studies have been carried out using I2/I3− and [Fe(CN)6]−3/[Fe(CN)6]−4 redox systems. Resistance of these photoelectroactive films towards electrochemical corrosion has also been investigated on the basis of current–voltage studies using Tafel plots.
