Abstract
Disclosed is a thin film solar cell for BIPV capable of improving a utility value for the exterior by visually changing a black color of an inorganic thin film solar cell into a color of reflected light therefrom to exhibit an exterior appearance having the color without substantially lowering efficiency required for a solar cell to thereby facilitate commercialization of the inorganic thin film solar cell. Also disclosed is a thin film solar cell for BIPV capable of maintaining a maximum power conversion efficiency (PCE) required for a solar cell when used as a finishing material of a building envelope, and visually changing a black color of an inorganic thin film solar cell into a color of reflected light therefrom to be suitable for the exterior with only a slight reduction of relative harvesting efficiency and a short circuit photocurrent density without a decrease of an open circuit voltage V.
