ELECTROLYTE FOR PHOTOELECTRIC CONVERSION ELEMENT, PHOTOELECTRIC CONVERSION ELEMENT USING THE ELECTROLYTE, AND DYE-SENSITIZED SOLAR CELL

摘要

Disclosed is an electrolyte for photoelectric conversion elements, which is capable of achieving high energy conversion efficiency without substantially containing iodine.  Also disclosed are a photoelectric conversion element using the electrolyte and a dye-sensitized solar cell.  The electrolyte for photoelectric conversion elements contains an ionic liquid and a carbon material having a specific surface area of 1,000-3,500 m2/g.  The carbon material is contained in an amount of 10-50 parts by mass per 100 parts by mass of the ionic liquid.
