Dye-sensitized solar cell with a buffer layer

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 (10) and a second electrode (20) facing each other. A buffer layer (30) and a porous layer (40) are sequentially formed on the first electrode (10) and a dye (50) is adsorbed on the porous layer (40). An electrolyte (60) is impregnated between the first electrode (10) and the second electrode (20). The dye-sensitized solar cell also includes an anti-reflection film (70) formed on the outer surface of the first electrode (10).
