The present invention provides a photoelectric conversion element comprising: an electron transport layer having an excellent electron transporting property and a sufficient reaction boundary layer, and having an excellent conversion efficiency. In the present invention, the photoelectric conversion element comprises: a first electrode, a second electrode; a stack of an electron transport layer and a hole transport layer, the stack being interposed between the first electrode and the second electrode; an electrolyte solution and a conductive agent; wherein the electron transport layer comprises an organic compound having a redox group that initiates repetitive oxidation-reduction reactions, the electrolytic solution being selected to provide stable reduction conditions for the redox group, and wherein the organic compound and the electrolyte solution co-operate, to form a gel layer. The conductive agent is located within the gel layer and remains at least partially in contact with the first electrode. |
