✦ Synopsis
ITO coating of n-semiconductors should protect them against photocorrosion in aqueous electrolytes. For this purpose n-GaAs/ITO electrodes were produced by the magnetron sputtering technique. The dependence of the photovoltaic properties on the post deposition annealing temperatures is shown. The best photovoltaic parameters are produced by 3200C annealing. Unfortunately, the ITO/n-GaAs electrodes also undergo corrosion in aqueous electrolytes. A model for this unexpected photoelectroehemical behaviour is developed.

A new method for the preparation of n-CdSe thin film electrodes which give a cell efficiency of 5.7% is presented. The band gap of the material deposited by this method was calculated and was found to be lower than the band gap reported earlier by various workers. The photoresponse is relatively con
