Thin n-type semiconductive films of CdTe, CdSe and their mixed compounds CdSexTe1-x, suitable for solar energy conversion, were prepared by catholic electrodeposition from an aqueous electrolyte onto titanium electrodes. An electrochemical cell was specially designed to perform electrodeposition in a boiling bath. The composition of the layers, their crystals structure, morphology and band-gap width were studied as functions of the electrochemical parameters and bath concentration. It is shown that the use of a high temperature improves the crystal quality of cadmium chalcogenide thin films even with solutions rather concentrated in selenous acid. CdSe or Se-rich CdSexTe1-x, layers tend in many cases to crystallize in the hexagonal (wurtzite) structure. © 1993. (EN)
