20150129035 | DYE-SENSITIZED PHOTOELECTRIC CONVERSION ELEMENT - A dye-sensitized photoelectric conversion device of the present invention has high energy conversion efficiency, even if the amount of iodine added into the electrolyte solution is significantly reduced. The dye-sensitized photoelectric conversion device has a porous photoelectrode layer comprising dye-sensitized semiconductor particles, an electrolyte solution layer, and a counter electrode layer in order. The electrolyte solution layer comprises an electrolyte solution containing 0.05 to 5 M of an aliphatic quarternary ammonium ion, 0.05 to 5 M of an imidazolium ion, and 0.1 to 10 M of iodide ion. The ions are dissolved in an organic solvent. Consequently, the amount of iodine added into the electrolyte solution can be reduced significantly. | 05-14-2015 |
