Zusammenfassung:Disclosed is a photoelectric element having an excellent conversion efficiency and provided with a hole transporting layer that is endowed with excellent hole transporting properties and a sufficiently large reaction interface. The photoelectric element of the invention has a pair of electrodes, an electron transporting layer and a hole transporting layer which are disposed between the electrodes, and an electrolyte solution. The hole transporting layer includes a first organic compound having a redox moiety capable of repeated oxidation and reduction. The electrolyte solution stabilizes a reduced state of the redox moiety. The organic compound and the electrolyte solution together form a first gel layer.
