    Abstract: Provided are a CIS/CGS/CIGS thin-film manufacturing method and a solar cell manufactured by using the same. The CIS/CGS/CIGS thin-film manufacturing method enables CIS, CGS, and CIGS thin-films through depositing an electrode layer on a substrate and depositing a light absorber layer by sputtering a single target of each of CIS including copper (Cu), indium (In), and selenium (Se) and CGS copper (Cu), gallium (Ga) and selenium (Se). In addition, a solar cell having excellent structural, optical and electrical properties is prepared by using the same. Thus, a thin-film can be prepared by depositing a CIG, CGS, or CIGS light absorber layer with a single sputtering process by using a single target of each of CIS (CuInSe2) and CGS (CuGaSe2), to thereby enable to manufacture thin-films of various characteristics according to a control of a composition ratio of In and Ga as well as simplification of the process, and to thus provide a very favorable effect on the economics and efficiency.
