碩士 === 國立成功大學 === 化學系碩博士班 === 98 === The CuInSe2, CuInxGa1-xSe2(CIGS) and CuGaSe2 nanoparticles were successfully prepared through colloidal method under nitrogen automosphere condition by using copper chlorides, indium chlorides, gallium chlorides, Se powder as precursors, and oleylamine as solvent. We discussed the effects of reactants concentration, reaction time and temperature on the morphology and composition of nanoparticles. Analysis crystal structure, shape, particle size, optical property and composition of nanoparticles by using XRD, TEM, UV-VIS-NIR and EDS. In this study, a non-vacuum process for coating the CIGS thin film is proposed to simplify the production process and reduce the investment costs. The CIGS alloy powder can be further grinded to a stable CIGS nanoparticles solution by wet-ball-milling method, the solution coating on Soda Lime glass that has been sputtering of molybdenum as CIGS thin film absorbing layer, we discussed the amount of beads in the wet-ball-milling for impact the uniformity of CIGS thin film. The thickness and uniformity of CIGS thin film were measured by using α-step instrument. In practical, the CIGS thin film was assembled into a solar cell, the photoelectric conversion efficiency is about 0.008 %.
