摘要:
A photoelectric element provided with an electron transport layer having excellent electron transport property and sufficiently wide reaction interface, and that has excellent conversion efficiency.The photoelectric element has an electron transport layer 3 and a hole transport layer 4 sandwiched between a pair of electrodes 2 and 5. The electron transport layer 3 is formed of an organic compound having a redox moiety capable of being oxidized and reduced repeatedly. The organic compound contains an electrolyte solution which stabilizes the reduced state of the redox moiety, and forms a gel layer 6 containing a sensitizing dye. Thus, the organic compound and the electrolyte solution in the electron transport layer 3 constitute the gel layer 6, while at the same time, the sensitizing dye is present within the gel layer 6, whereby the reaction interface of the organic compound is enlarged, improving the conversion efficiency and the electron hand-over efficiency from the sensitizing dye to the organic compound in the electron transport layer 3, as a result of which the electron transport efficiency is improved.
