Abstract
Provided are a novel dye-sensitized solar cell using an organic solvent-free electrolyte and capable of exhibiting excellent photoelectric conversion characteristics, and a novel and practical organic solvent-free electrolyte for such a dye-sensitized solar cell. An organic solvent-free electrolyte containing a conductive carbon material, water, and an inorganic iodine compound is used as an electrolyte for a dye-sensitized solar cell. The organic solvent-free electrolyte is preferably a quasi-solid electrolyte and the conductive carbon material in the organic solvent-free electrolyte has a surface area of preferably from 30 to 300 m2/g.
Claims5
