DYE-SENSITIZED SOLAR CELL AND PROCESS FOR PRODUCING THE DYE-SENSITIZED SOLAR CELL

WIPO Patent Application WO/2009/157497

A1

Disclosed is a dye-sensitized solar cell that can realize a high efficiency and a high service life (long-term stability) as a result of improving or solving problems of conventional dye-sensitized solar cells, that is, a low conversion efficiency due to the limitation of titanium oxide and a dye and a difficulty of ensuring prolongation of the service life (long-term stability), for example, due to liquid leakage of the dye or electrolysis solution.  Also disclosed is a process for producing the dye-sensitized solar cell. For example, a product obtained by covering a dye-adsorbed zeolite with (porous) titanium oxide and allowing the assembly to gel with a polymer absorber, a product obtained by allowing a dye-adsorbed (porous) titanium oxide to gel in the same manner as described above, or a product obtained by including a silicon or a compound semiconductor in the above product is dried and condensed so that viscosity (viscoelasticity) is not lost.  The dried and condensed product, either after size reduction or the like or in the state as such, is subjected to further processing such as integral pressure condensation to form an even, high-density, and elastic rubbery gel material.  The dye-sensitized solar cell comprises the rubbery gel material (including the dye, electrolysis solution, and electrode produced in the same form).
