Rising global warming and the growing need for energy are important issues that lead to the proliferation of renewable energy. The aim of this project was to investigate the effect of adding Cadmium sulfide and Zinc sulfide in Copper(II) sulfide and Lead(II) sulfide to improve the sensivity by Successive ionic layer adsorption and reaction method in light and dark conditions. The best sell made during this project Cu sheet /8CuS/2CdS / 8 PbS (0.5 M). The largest difference between the current intensity in the dark and light for this cell in the potential of one volt is 14 mA. SEM images of the cell showed that the semiconductor particles were in the nanometer range. The photoelectrochemical properties have been investigated using electrochemical techniques of chronoamperometry,cyclic voltammetry and chronopotentiometry.
