Abstract:
The present disclosure provides a photoelectric conversion element including a lower electrode, a photoelectric conversion layer, and an upper electrode in this order; a voltage is applied between the lower electrode and the upper electrode; the photoelectric conversion layer contains a first organic compound and a second organic compound; the first organic compound has a lower oxidation potential than the second organic compound, and ΔE represented by the following formula (A) satisfies the following formula (B); where ΔE=oxidation potential of first organic compound−reduction potential of second organic compound (A) ΔE≥1.79[V] (B).
