PURPOSE: An electrolyte composition for dye-sensitized solar cells containing a novel imidazolium salt is provided to ensure excellent ion conductivity. CONSTITUTION: An electrolyte composition for dye-sensitized solar cells contains imidazolium salt and iodine. The imidazolium salt is denoted by chemical formula 1. In chemical formula 1, R1 is alkyl group or vinyl group of C1-C10; R2 is H or alkyl group of C1-C3; and n1 is 1-5 integer. The iodine is contained in 0.5-10 wt% of the imidazolium salt. The composition additionally contains acetonitrile, 3-methoxy propionitrile, valeronitrile, ethylene carbonate, propylene carbonate, gamma-butyrolactoen, or N-methyl-2-pyrrolidone. |
