Abstract
A photoelectric conversion element including a substrate, and a photoelectric conversion layer disposed on or above the substrate, wherein the photoelectric conversion layer includes an organic material (A) represented by General Formula (1), an electron-donating material (B) having a repeating unit structure and having an energy level of the highest occupied molecular orbital (HOMO) being 5.0 eV or greater, and an electron-accepting material (C), wherein a mass ratio (A+B):C is from 1.0:1.0 through 3.0:1.0, where, in General Formula (1), R1 is each independently an alkyl group having from 2 through 8 carbon atoms; n is each independently an integer of from 1 through 2; X1 and X2 are each independently a hydrogen atom or a halogen atom; and A is represented by General Formula (2), General Formula (3), or General Formula (4) and R2 to R4 are each independently an alkyl group having from 8 through 22 carbon atoms.
