Working electrode of dye-sensitized solar cell, dye-sensitized solar cell including the same, and method for producing working electrode of dye-sensitized solar cell

摘要

PPROBLEM TO BE SOLVED: To enlarge a surface area of a porous oxide semiconductor layer with sensitizing dye on its surface to take in much more light and resultantly to improve photoelectric conversion efficiency. PSOLUTION: The action pole 2 of a dye-sensitized solar battery is composed of a transparent base material 11, a transparent conductive film 12 and a porous oxide semiconductor layer 15 which is made of a lamination of a first layer 13 and a second layer 14 of porous oxide semiconductor, and a lower face of the first layer 13 is to be a concavo-convex face 13b and an upper face of the second layer 14 is to be a flat face 14a.
