Abstract
A solar cell includes: a first electrode; a first hole transport layer containing nickel; an inorganic material layer containing titanium; a light-absorbing layer converting light into electric charge; and a second electrode. The first electrode, the first hole transport layer, the inorganic material layer, the light-absorbing layer, and the second electrode are layered in that order. The light-absorbing layer contains a perovskite compound represented by a formula AMX3, where A is a monovalent cation, M is a divalent cation, and X is a monovalent anion.
