Dye-sensitized solar cell

Abstract

The present invention is a dye-sensitized solar cell including a working electrode having a conductive substrate that is capable of transmitting light, and a porous oxide semiconductor layer that is provided on the conductive substrate; a counter electrode that is provided to face the porous oxide semiconductor layer of the working electrode; a photosensitizing dye that is supported in the porous oxide semiconductor layer of the working electrode; and an electrolyte that is disposed between the working electrode and the counter electrode, in which solar cell the average particle size of the entirety of the semiconductor particles that constitute the porous oxide semiconductor layer is 100 nm or less, the electrolyte contains inorganic particles and is gelled by the inorganic particles, and the reflectance of the electrolyte is higher than the reflectance of the porous oxide semiconductor layer.
