Dye-sensitized solar cell having enlarged wavelength range for light absorption and method of fabricating same

摘要

A dye-sensitized solar cell with an enlarged effective wavelength range for light energy absorption and enhanced photoelectric conversion efficiency, and a method of fabricating such a solar cell are disclosed. The dye-sensitized solar cell comprises a first electrode comprising a light transmission material, and a second electrode facing the first electrode. A porous layer is formed on the first electrode, and a composite dye is absorbed tothe porous layer. The composite dye comprises two or more dye materials. An electrolyte is impregnated between the first and second electrodes.
