Abstract:
PURPOSE: An environment-friendly polymer gel electrolyte composition facilitates the injection of electrolyte, reduces leakage and volatilization, thereby providing a dye-sensitized solar cell with excellent long term stability and high efficiency. CONSTITUTION: A polymer gel electrolyte composition for a dye-sensitized solar cell comprises a polysaccharide-based polymer aqueous solution and a liquid electrolyte mixed of an oxidation-reduction derivative and an organic solvent. A manufacturing method of a polymer gel electrolyte composition comprises a step of manufacturing a polymer gel aqueous solution by dispersing polysaccharide-based polymer into a solvent; a step of manufacturing a liquid electrolyte by mixing an oxidation-reduction derivative and an organic solvent; and a step of mixing the polysaccharide-based polymer gel aqueous solution and liquid electrolyte.
