The present disclosure provides a perovskite solar cell having high conversion efficiency and high durability. Provided is a solar cell comprising a first electrode; a second electrode; a perovskite photoabsorber layer located between the first electrode and the second electrode; a first semiconductor layer located between the first electrode and the photoabsorber layer; and a second semiconductorlayer located between the second electrode and the photoabsorber layer. The first semiconductor layer contains Li. The second semiconductor layer contains LiN(SO2CF3)2. The second semiconductor layercontains poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine]. In the second semiconductor layer, a molar ratio of LiN(SO2CF3)2 to poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] is not less than 0.15 andnot more than 0.26.
