Abstract: A photoelectric conversion element includes a first layer, a second layer, and a third layer that are laminated in this order. The first layer is formed of a plurality of particles including an inorganic semiconductor as a main component, an aggregate of the particles, or a thin film including an inorganic semiconductor as a main component. The second layer is provided on a surface of each of the particles or the aggregate and is formed of a plurality of particles including a perovskite structure as a main component, an aggregate of the particles, or a thin film including a perovskite structure as a main component. The third layer is formed of a plurality of particles including an organic metal complex as a main component, an aggregate of the particles, or a thin film including an organic metal complex as a main component.
