<P>PROBLEM TO BE SOLVED: To provide an electrolyte solution inhibiting the deterioration of a battery and the coloring of a conductive substrate by removing iodine generated in an electrolyte, and a photoelectric conversion element comprising the same, and a dye-sensitized solar cell comprising the same. <P>SOLUTION: A dye-sensitized solar cell or a photoelectric conversion element comprises a semiconductor electrode layer 1 made of dye-sensitized semiconductor particles, an electrolyte layer 2, and a counter electrode 3 on a conductive support in the order presented above. The electrolyte layer 2 contains an imidazolium salt and/or an inorganic salt, or a quaternary ammonium compound as an electrolyte solute, and a thiol compound or a thiosulfate as a reducing agent. The amount of addition of the thiol compound is 0.0001 mol/L or larger, and smaller than 0.2 mol/L. <P>COPYRIGHT: (C)2012,JPO&INPIT |
