Abstract

To provide a tandem dye-sensitized solar cell having a novel structure capable of improving the light absorption efficiency and being manufactured less expensively. A dye-sensitized solar cell 10 is configured by including, in order from the light incident side, an anode substrate 12, a first dye-carrying porous oxide semiconductor layer 14, a first electrolyte layer 16a, an electrolyte redox catalyst layer 18, a second dye-carrying porous oxide semiconductor layer 20, a porous support layer 19, a second electrolyte layer 16b, and a cathode substrate 22. The electrons extracted from a conductor layer 12b by a conductor are introduced into the cathode substrate 22, so that a battery circuit, for example, for a lighting power source is configured.
