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: Disclosed is a bifacial thin film solar cell, particularly a bifacial CuInGaS, thin film solar cell, fabricated by a paste coating method. According to several embodiments, the bifacial thin film solar cell results in a higher conversion efficiency of bifacial illumination than the simple sum of the efficiencies of upper and lower side illumination only, unlike those previously reported. The bifacial thin film solar cell exhibits many other effects described in the specification.
