<P>PROBLEM TO BE SOLVED: To provide an electrolytic solution showing sufficient photoelectric conversion efficiency when incorporated into a dye-sensitized solar cell, and comprising an ionic liquid having high-temperature durability. <P>SOLUTION: The electrolytic solution contains electrolytes including iodine, lithium iodide, and 1-ethyl-3-methylimidazolium iodide, and an ionic liquid containing 1-ethyl-3-methylimidazolium bis(fluorosulfonyl) imide. It is preferable that the concentration of iodine is in the range of 0.1 to 0.6 mol/L, the concentration of lithium iodide is in the range of 0.05 to 0.3 mol/L, and the concentration of 1-ethyl-3-methylimidazolium iodide is in the range of 1.0 to 3.0 mol/L. <P>COPYRIGHT: (C)2012,JPO&INPIT |
