Abstract

Steam deposition techniques for fabricating CIGS (Copper Indium Gallium Diselenide) thin films require accurate environmental control and high costs, for which several alternative fabrication techniques have been developed. In this research the liquid phase method has been used with variations of decantation which will further affect the energy of the band produced. The CIGS film has been deposited on ITO (Indium Tin Oxide) substrate with doctor blade technique and XRD measurement which shows the resulting sample has a tetragonal crystal structure. SEM results show that the porosity of the film varies and the grain size of the CIGS increases with the number of decantation processes of oleylamine solvents. Band energy gap from CIGS decreases as oleylamin solvent decreases after the decantation process.
