A dye-sensitized solar cell, a photoanode thereof, and a method for manufacturing the same are disclosed. The photoanode of the dye-sensitized solar cell of the present invention is prepared by a porous semiconductor layer absorbing two kinds of organic sensitized dyes, and one organic sensitized dye is represented by the following formula (I):
wherein, D
