摘要： 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.
