Abstract: A solar cell includes a first substrate, a first hole transport layer, a first photoelectric conversion layer containing a perovskite compound, and a second photoelectric conversion layer containing a photoelectric conversion material in this order. A band gap of the perovskite compound is greater than a band gap of the photoelectric conversion material. With respect to an absorption wavelength of the first photoelectric conversion layer 3, a refractive index nA of the first hole transport layer 2 satisfies refractive index of the first substrate≤nA≤refractive index of the first photoelectric conversion layer. Further, with respect to a transmission wavelength of the first photoelectric conversion layer 3 and an absorption wavelength of the second photoelectric conversion layer 5, a refractive index nB of the first hole transport layer 2 satisfies refractive index of the first substrate≤nB≤refractive index of the first photoelectric conversion layer.

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.
