摘要：

The cathodic current density for CdTe electrodeposition from ammoniacal alkaline baths (pH 10.7 similar to 10.8) was enhanced by photo-irradiation of the cathode surface. Voltammetric analysis revealed that the photo-induced enhancement was caused by CdTe deposit on the growing surface. By this irradiation, deviation of the composition of the resulting CdTe film from stoichiometry was depressed and current efficiency increased. The photo-assisted growth was discussed in terms of the deposition mechanism.
