Experimental and theoretical studies of the structural and optical properties of Copper Indium Gallium diSelenide thin films have been performed. Thin films of CIGS were deposited on glass substrates by chemical bath deposition. From the XRD results of the films, it is found that the films are of chalcopyrite type structure. The lattice parameter were determined as a = 5.72 Å and c = 11.462 Å. The optical properties of the thin films were carried out with the help of spectrophotometer. First principles density functional theory calculations of the band structure, density of states and effective masses of electrons and holes of the CIGS crystals have been done by computer simulations. The experimental data and theoretically calculated data have demonstrated good agreement.
