Dye-sensitized solar cell

Abstract

Disclosed is a dye-sensitized solar cell which includes a working electrode having a porous titanium oxide layer on a conductive substrate capable of transmitting light, a counter electrode disposed so as to face the working electrode, a photosensitizing dye supported on the porous titanium oxide layer of the working electrode, and an electrolyte disposed between the working electrode and the counter electrode. The porous titanium oxide layer includes a rutile crystal-containing layer containing an anatase crystal-type titanium oxide composed of an anatase crystal and a spherical rutile crystal-type titanium oxide composed of a rutile crystal, and a content of the rutile crystal-type titanium oxide in the rutile crystal-containing layer is from 3 to 15% by mass.
