Abstract: Disclosed is a bifacial thin film solar cell that is applicable to a BIPV window, particularly a bifacial CIGS thin film solar cell that can generate electricity by both sunlight and indoor illumination due to its ability to absorb light at both front and rear sides. According to several embodiments, visible light in a particular wavelength region can be transmitted through the semi-transparent thin film solar cell. In addition, high stability and safety of the thin film solar cell can be ensured because there is no need to use organic materials and liquid electrolytes. Furthermore, the fabrication cost of the thin film solar cell can be reduced by a low cost solution process. The thin film solar cell exhibits various other effects described in the specification.

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.
