<p><P>PROBLEM TO BE SOLVED: To provide a dye-sensitized photoelectric conversion element wherein an working electrode and/or the counter electrode themselves can impede diffusion of iodine and can prevent reduction of a power generation area. <P>SOLUTION: In the dye-sensitized photoelectric conversion element 1, a first working electrode 3, the counter electrode 4, and a second working electrode 5 each have a structure wherein a plurality of conductive wires are knitted into a mesh, and the first working electrode, the counter electrode, and the second working electrode are stacked in the order from an incident side of light. When an aperture ratio of the mesh of the first working electrode is denoted by (a) and an aperture ratio of the mesh of the counter electrode is denoted by (b) and an aperture ratio of the mesh of the second working electrode is denoted by (c), they satisfy relational expressions of (a)>(c) and (b)>(c). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
