Abstract

To provide a novel photoelectric conversion device that is highly convenient, useful, or reliable. The photoelectric conversion device includes a first electrode, a second electrode, and a first unit. The first unit is located between the first electrode and the second electrode. The first unit contains a first electron-donating material and a first electron-accepting material. The first electron-donating material is a condensed aromatic compound, and the first electron-accepting material has a perylene skeleton and two or more alkyl groups. The alkyl groups each independently have 1 to 13 carbon atoms.
