Abstract
There is provided a tandem-type dye-sensitized solar cell having a novel structure whereby optical absorption efficiency is improved and which can be manufactured at low cost. A dye-sensitized solar cell 10 comprises an anode substrate 12, a first dye-carrying porous oxide semiconductor layer 14, an electrolytic solution layer 16a, a porous support layer 18, a second dye-carrying porous oxide semiconductor layer 20, an electrolytic solution layer 16b, and a cathode substrate 22, arranged in order from an optical incidence side. The porous support layer 18 supports an iodine redox catalyst layer 19. Electrons derived by a conductor from a conductor layer 12b are introduced to the cathode substrate 22, thereby configuring, for example, a battery circuit for lighting purposes.
