ORGANIC PHOTOELECTRIC CONVERSION ELEMENT

摘要

Disclosed is an organic photoelectric conversion element having high photoelectric conversion efficiency. The organic photoelectric conversion element comprises an anode, a cathode, and an organic active layer provided between the anode and the cathode, wherein the organic active layer contains a multi-exciton generator. As the multi-exciton generator, a compound semiconductor containing at least one element selected from Cu, In, Ga, Se, S, Te, Zn and Cd is used. Preferably, the compound semiconductor has multiple energy levels in the energy gap thereof. Also preferably, the compound semiconductor is a nano-sized granular material preferably having a p-type semiconductor attached on the surface thereof.
