DYE-SENSITIZED SOLAR CELLS

摘要

The present invention discloses an innovative way to improve the conversion efficiency of solar energy into electric energy of dye-sensitized solar cells. The solar cells of the present invention present a film obtained by painting a light reflective coating (6) onto the outer surface of the counter-electrode (4). A commercial paint of any color can be used. The solar cells of the present invention usually comprise two glass sheets coated with a transparent and electrically conductive layer (1) and (5), a photoelectrode (2), an electrolyte (3), a counter-electrode (4) and a light reflective paint film applied onto the outer surface of the counter-electrode and obtained by painting a light reflective coating (6). After applying this reflective film (6) onto the outer surface of the counter-electrode (4) a series of remarkable results were obtained; coating with a white paint as a reflective film significantly increased the solar cell efficiency up to 30%.
