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, a refractive index nof the first hole transport layersatisfies refractive index of the first substrate≤n≤refractive index of the first photoelectric conversion layer. Further, with respect to a transmission wavelength of the first photoelectric conversion layerand an absorption wavelength of the second photoelectric conversion layer, a refractive index nof the first hole transport layersatisfies refractive index of the first substrate≤n≤refractive index of the first photoelectric conversion layer.
