An optical element utilizing a molecular heterojunction

摘要

An optical element utilizing a molecular heterojunction, includes a first redox material film comprising first redox material, a second redox material film comprising second redox material having a different redox potential from that of the first redox material and connected to the first redox material film, a first electrode connected to the first redox material film, and a second electrode connected to the second redox material film. The optical element exhibits photoconduction property when it is irradiated with light, by that the states of electrons in the first and second redox material are controlled by the light irradiation utilizing the difference in the redox potential of the redox material.
