Abstract
Provided is a photoelectric element that includes an electron transport layer having excellent electron transport properties and a sufficiently large reaction interface and has low resistance loss and excellent conversion efficiency between light and electricity. The photoelectric element includes a first electrode, a second electrode, an electron transport layerand a hole transport layerinterposed between the first electrodeand the second electrode, an electrolyte solution, and a sensitizing dye. The electron transport layerincludes an organic compound having an oxidation-reduction site capable of repeated oxidation-reduction. The electrolyte solution serves to stabilize a reduction state of the oxidation-reduction site. The organic compound and the electrolyte solution form a gel layer. The sensitizing dye is provided in contact with the electron transport layer. The hole transport layercontains a charge transporter serving to reduce an oxidized form of the sensitizing dye and having a number average molecular weight of 2,000 or more and 100,000 or less.
