Abstract: Provided is a CIGSSe thin film for a solar cell, a method for preparing the same, and a solar cell using the same. More particularly, the CIGSSe thin film for a solar cell shows a decrease in peak intensity of sulfur from the surface of the thin film to the local minimum value point of sulfur content in the depth direction, after the analysis based on the Auger electron spectroscopy, and thus controls the band-gap in the thin film. Therefore, the solar cell including the CIGSSe thin film shows an excellent effect in improving photoelectric conversion efficiency.
