Claim 0:
1. A solar cell comprising:
a first electrode;
a second electrode;
a photoelectric conversion layer disposed between the first electrode and the second electrode; and
an electron transport layer disposed between the first electrode and the photoelectric conversion layer,
wherein at least one electrode selected from the group consisting of the first electrode and the second electrode has a light-transmitting property,
the photoelectric conversion layer contains a perovskite compound composed of a monovalent cation, a divalent cation, and a halogen anion,
the electron transport layer contains a metal oxynitride having electron conductivity, and
the metal oxynitride is a niobium oxynitride and has an electrical conductivity of greater than or equal to 1×10−7 S/cm, and
in the niobium oxynitride, a ratio N/O of the amount of substance of N to the amount of substance of O is greater than or equal to 0.05 and less than or equal to 0.28.
