Abstract: The invention provides a dye-sensitized solar cell with an improved electrode structure and enhanced energy efficiency, and a method of manufacturing same. The dye-sensitized solar cell includes a light-transmission first electrode with a first surface, and a second electrode with a second surface facing the first surface of the first electrode. The second surface of the second electrode has convexo-concave portions. A porous layer is formed on the first surface of the first electrode. A dye is absorbed into the porous layer. An electrolyte is impregnated between the first and the second electrodes.

Abstract: 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 to the porous layer. The composite dye comprises two or more dye materials. An electrolyte is impregnated between the first and second electrodes.

Abstract: Disclosed is a dye-sensitized solar cell with enhanced photoelectric conversion efficiency. The dye-sensitized solar cell includes a first electrode of a light transmission material, a second electrode facing the first electrode, and a dye-absorbed porous layer formed on the first electrode. An electrolyte is injected between the first and the second electrodes. The porous layer contains first and second materials differing from each other in conduction band energy level.

Abstract: It is an object of the present invention to provide a dye-sensitized solar cell which has high conversion efficiency and excellent endurance. A dye-sensitized solar cell includes a first electrode and a second electrode facing each other. A buffer layer and a porous layer are sequentially formed on the first electrode and a dye is adsorbed on the porous layer. An electrolyte is impregnated between the first electrode and the second electrode. The dye-sensitized solar cell also includes an anti-reflection film formed on the outer surface of the first electrode.
