PURPOSE: A polyelectrolyte for dye-sensitized solar cell and a dye-sensitized solar cell using thereof are provided to solve leakage problem of liquid electrolyte and to have same energy conversion efficiency as the liquid electrolyte. CONSTITUTION: A polyelectrolyte(300) for dye-sensitized solar cell comprises an aqueous solution which includes PEO-PPO-PEO tri block copolymer and electrolyte solution which includes organic solvent, and oxidation-reduction derivative and additive. The organic solvent is more than one kind or two kinds of mixed solution which is selected from a group consisting of acetonitrile, ethylene carbonate, polypropylene carbonate, dimethyl carbonate, diethyl carbonate, ethyl methyl carbonate, tetrahydrofuran, 3- methoxy propionnitrile, and gamma-butyrolactone. The oxidation-reduction derivative is one kind of mixture which is selected from a group consisting of lithium iodide, sodium iodide, iodination potassium, lithium bromide, sodium bromide, potassium bromide, quaternary ammonium salt, imidazolium salt, and pyridinium salt. |
