PHOTOELECTRIC ELEMENT

WIPO Patent Application WO/2013/099689

A1

[Problem] To provide a photoelectric element with high photoelectric conversion efficiency. [Solution] The present invention pertains to a photoelectric element provided with: a first electrode (1); a second electrode (2) positioned facing the first electrode (1); a semiconductor (3) disposed on the surface of the first electrode (1) facing the second electrode (2); a photosensitizer (4) supported on the semiconductor (3); a first charge transport layer (5) disposed between the first electrode (1) and the second electrode (2); and a second charge transport layer (6) disposed between the first charge transport layer (5) and the second electrode (2). The first charge transport layer (5) and the second charge transport layer (6) each independently have a redox substance, and the redox potential of the redox substance of the first charge transport layer (5) is more noble than the redox potential of the redox substance of the second charge transport layer (6).
