Abstract
Provided is a photoelectric conversion element including a first electrode, an electron-transporting layer, a hole-transporting layer, and a second electrode, wherein the hole-transporting layer and the second electrode are in contact with each other, and the hole-transporting layer satisfies the following formula:0%<(50)≤0.75%where an average thickness of the hole-transporting layer is determined as X (nm), and Rc(50) is a ratio of an area of projected parts that are projected from a standard line towards the second electrode, where the standard line is present at a position that is away, by X+50 (nm), from an opposite surface of the hole-transporting layer to a surface of the hole-transporting layer in contact with the second electrode.
