We have prepared cell with a variable thickness of CdS layer to get an understanding of the optimum thickness as well as it lowest limits for practical purposes. We used quantum efficiency current-voltage and light beam induce current testing to investigate cell performance as well as nonuniformity. The best results are achieved with 0.1 micron CdS layer. This number does depend slightly on the quality of CdCl2 treatment and the thickness of the CdTe layer. For the case of magnetron sputtered… CONTINUE READING
