Abstract
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 semiconductor layer located between the second electrode and the photoabsorber layer. At least one electrode selected from the group consisting of the first electrode and the second electrode is light-transmissive. The first semiconductor layer contains Li. The second semiconductor layer contains LiN(SOCF). The second semiconductor layer contains poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine]. In the second semiconductor layer, a molar ratio of LiN(SOCF)to poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] is not less than 0.15 and not more than 0.26.
