Abstract

In this paper, we were interested in the investigation of the optimum parameters for the elaboration of the CuGaS2 compounds destined to the solar cells fabrication .These parameters that are constituted essentially of the temperature, the duration and the rate of the heating stage, the fusion, the crystallization and the cooling were optimised. The prepared sample presented a good morphology. Analysis by x ray diffraction has allowed the study of the crystalline structure of the obtained CuGaS2 ingot and the determination of the different crystalline planes and the different present phases. These analysis have shown that the obtained ingot is polycrystalline and of chalcopyrite structure..
