Abstract:

Copper indium gallium diselenide alloy powders were synthesised by mechanical alloying of elemental Cu, In, Ga and Se in a planetary ball mill. Effect of milling time on structure of CIGS nanoparticles was studied using X-ray diffraction measurements. Influence of milling time on phase evolution, cell parameters and crystallite size was reported in detail. FESEM analysis provided information on the morphological changes of CIGS particle during milling. EDAX results revealed dependence of milling time on composition of product particles. A tendency of increasing Cu and decreasing Se concentration with milling time was observed. Cu and Ga rich CIGS nanoparticles were obtained after milling for 6 h. The sample obtained after 6 h of milling showed homogeneous composition.
