Abstract
A photoelectric conversion element may include a first substrate, a first transparent electrode disposed on the first substrate, a hole-blocking layer disposed on the first transparent electrode, an electron-transporting layer that is disposed on the hole-blocking layer and includes an electron-transporting semiconductor on a surface of which a photosensitizing compound is adsorbed, a hole-transporting layer that is connected to the electron-transporting layer and includes a hole-transporting material, and a second electrode disposed on the hole-transporting layer, wherein the photoelectric conversion element includes an output extraction terminal part configured to extract electricity out from the photoelectric conversion element, and the output extraction terminal part is formed with a plurality of micropores piercing through the hole-blocking layer.
