| 摘要 |
The present invention provides a photoelectric conversion element comprising: an electron transport layer which has an excellent electron transport property and a sufficient reaction interface, and having excellent conversion efficiency. In the present invention, a photoelectric conversion element comprises: a first electrode; a second electrode; a stack of an electron transport layer and hole transport layer, the stack being interposed between the first electrode and the second electrode; an electrolyte solution; and a conductive agent; the electron transport layer containing an organic compound having a redox moiety causing repetitive oxidation-reduction reactions, the electrolyte solution being selected to give stable reduction condition of the redox moiety, the organic compound and the electrolyte solution being cooperative to form a gel layer. Wherein the conductive agent is present within the gal layer and kept at least partly in contact with the first electrode.
