Electrodeposition and stripping of tellurium and cadmium telluride (CdTe) have been studied by means of simultaneous voltammetric and electrogravimetric experiments. The combined analysis of the results is a powerful method for studying these complex electrochemical systems. The experiments were performed in a sulfate electrolyte containing HTeO2+ with or without CdSO4. The several oxidation/reduction waves are related to the different deposition/stripping processes. The reduction of HTeO2+ to Te-O and the cathodic stripping of Te-O to H2Te are clearly shown in cadmium free electrolytes. Also, the anodic stripping process of both Te-O and CdTe is analyzed and discussed in comparison with other published work.
