DYE-SENSITIZED SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

Provided is a dye-sensitized solar cell, and a method for manufacturing the same, that in a technology in which a current collector electrode is used instead of a transparent conductive film, can be manufactured by a simple cell producing operation and is capable of achieving a desirably thin thickness for the current collector electrode. A dye-sensitized solar cell 10 includes a transparent substrate 12 provided on the side where solar light is incident, a conductive substrate 14 that serves as a cathode and is provided opposite the transparent substrate 12, a porous semiconductor layer 16, a porous conductive metal layer 18 that serves as a current collector electrode, and a porous insulating layer 20. The porous conductive metal layer 18 is a layer that has a thickness of 0.3 μm to 100 μm and is deposited on the porous insulating layer 20. The porous conductive metal layer 18 is arranged in contact with the porous semiconductor layer 16 on the side that is opposite to the transparent substrate 12, and serves as an anode. The porous insulating layer 20 is arranged on the side of the porous conductive metal layer 18 opposite to the porous semiconductor layer 16. The conductive substrate 14 is arranged facing the porous insulating layer 20.
