    摘要: A method for fabricating a copper-indium-gallium-diselenide (CIGS) compound thin film is provided. In this method, a substrate is first provided. An adhesive layer is formed over the substrate. A metal electrode layer is formed over the adhesive layer. A precursor stacked layer is formed over the metal electrode layer, wherein the precursor stacked layer includes a plurality of copper-gallium (CuGa) alloy layers and at least one copper-indium (CuIn) alloy layer sandwiched between the plurality of CuGa alloy layers. An annealing process is performed to convert the precursor stacked layer into a copper-indium-gallium (CuInGa) alloy layer. A selenization process is performed to convert the CuInGa alloy layer into a copper-indium-gallium-diselenide (CuInGaSe) compound thin film.
