Abstract
A photosensor includes a first electrode, a second electrode that opposes the first electrode, and a photoelectric conversion layer that is disposed between the first electrode and the second electrode and converts incident light into electric charges. At least one electrode selected from the group consisting of the first electrode and the second electrode is light-transmissive. The photoelectric conversion layer contains a perovskite compound. The fluorescence spectrum of the perovskite compound has a first peak at a first wavelength and a second peak at a second wavelength that is longer than the first wavelength. The photoelectric conversion layer is in ohmic contact with each of the first electrode and the second electrode.
