ELECTROLYTE FOR DYE-SENSITIZED SOLARCELL COMPRISING PYRIDINIUM IODIDE BASED IONIC LIQUID, DYE-SENSITIZED SOLARCELL COMPRISING THE ELECTROLYTE AND PREPARATION METHOD OF THE DYE-SENSITIZED SOLARCELL

摘要

PURPOSE: An electrolyte for dye-sensitized solar cell is provided to improve quantum efficiency of dye-sensitized solar cell by including pyridinium iodide-based ionic liquid. CONSTITUTION: An electrolyte for dye-sensitized solar cell comprises an organic solvent, an oxidation-reduction derivative, a pyridinium iodide-based ionic liquid, and t-butylpyridine. The organic solvent is a mixture of one or two kinds selected from ethylene carbonate, propylene carbonate, dimethyl carbonate, diethyl carbonate, ethyl methyl carbonate, tetrahydrofuran, 3-methoxypropionitrile and gamma-butyrolactone.
