| Abstract: | Electrochemical deposition of cadmium telluride from acidic solutions containing CdSO4 and TeO2 is studied and the current-potential expression for this reaction is presented. The electrochemically deposited CdTe films are photoactive, and the maximum cathodic photocurrent due to hydrogen evolution is observed at CdTe films deposited at -0.40V. The photocurrents of the as-grown CdTe films are relatively small compared with those of CdTe single crystals. The major reason for this low efficiency is the effective recombination of hole-electron pairs at grain boundaries and at the surface. The photocurrents are increased significantly by the increase of crystallite diameter by the heat-treatment in a He atmosphere and by the removal of surface Te, which acts as a recombination center, by the etching treatment. |
