Abstract
Disclosed is a novel ionic liquid gel electrolyte having high photoelectric conversion efficiency. Also disclosed are a novel dye-sensitized photoelectric conversion device using such an ionic liquid gel electrolyte, and a solar cell composed of such a dye-sensitized photoelectric conversion device. Specifically disclosed is an ionic liquid gel electrolyte obtained by gelling a liquid electrolyte by using an ionic organic oligomer gelling agent represented by the general formulae (1) and (2) below. Also specifically disclosed are a dye-sensitized photoelectric conversion device, wherein the ionic liquid gel electrolyte is arranged between a counter electrode and a dye-absorbed semiconductor substrate which is arranged in contact with a transparent conductive substrate, and a solar cell.
