Abstract

A solar cell module includes a substrate, an element section disposed on the substrate and including a unit cell, a sealer, and a first material. The element section and the first material are housed in a space sealed with the sealer. The unit cell includes a pair of electrodes having conductivity and includes a light-absorbing layer located between the pair of electrodes and converting light into electric charge. The light-absorbing layer includes a perovskite compound represented by a compositional formula AMX₃, where A represents a monovalent cation, M represents a divalent cation, and X represents a monovalent anion. The first material is an amine derivative represented by a compositional formula (Q₁Q₂Q₃-N—H)Y, where Q₁, Q₂, and Q₃ each independently represent a functional group including at least one element selected from the group consisting of carbon, hydrogen, nitrogen, and oxygen; and Y represents a halogen.
