摘要

The present invention relates toDisclosed are a dye-sensitized solar cell having improved efficiency by using back surface coloring, and a window including having same. The dye-sensitized solar cell according to the present invention may be a dye-sensitized solar cell in which two boards are spaced a predetermined distance apart from and opposite each other to face each other, and an electrolyte is filled between the said upper and lower boards. The dye-sensitized solar cell includescomprises: a first coating layer including a curable material on the outside of one of the said two boards; and a print paint layer applied on the said first coating layer. In the dye-sensitized solar call according to the present invention, a white coating layer may be applied on a the back surface of one of the boards, and prints paints having various colors may be applied on the said coating layer. ParticularlyIn particular, aesthetics may be improved by using the back surface coloring, and also, the efficiency of the cell may be improved due to back scattering when compared to a conventional technology in which light emitted through a front surface passes as-is through a the back surface of a substrate.
