Abstract
Disclosed is an organic photoelectric conversion element having high photoelectric conversion efficiency and high durability. Also disclosed are a solar cell and an optical sensor array, each using the organic photoelectric conversion element. The organic photoelectric conversion element comprises a bulk heterojunction layer wherein an n-type semiconductor material and a p-type semiconductor material are mixed. The organic photoelectric conversion element is characterized in that the n-type semiconductor material is a polymer compound and the p-type semiconductor material is a low-molecular-weight compound.
