Provided is a photoelectric element with superior conversion efficiency, that is equipped with an electron transport layer having superior electron transport properties and a sufficiently wide reactive interface. In the photoelectric element, the electron transport layer (3) and a hole transport layer (4) are disposed between a pair of electrodes (2, 5). The electron transport layer (3) is formed by being provided with an organic compound that has an oxidation-reduction part capable of repeated oxidation-reduction. The organic compound is formed as a gel layer (6) comprising an electrolytic solution that stabilizes the reduced state of the oxidation-reduction part, and sensitizing dye is present within the gel layer (6). Accordingly, the formation of the gel layer (6) by the organic compound and the electrolytic solution of the electron transport layer (3) and the presence of sensitizing dye in the gel layer (6) results in the expansion of the reactive interface of the organic compound and the improvement of conversion efficiency, as well as the improvement of electron transportation efficiency and the improvement of electron transfer efficiency from the sensitizing dye to the organic compound in the electron transport layer (3). |
