Abstract:
A photoelectric conversion material dispersion liquid of an embodiment includes: perovskite crystal particles having a composition represented as ABX3, where A is a monovalent cation of an amine compound, B is a divalent cation of a metal element, and X is a monovalent anion of a halogen element, and having an average particle diameter of not less than 10 nm nor more than 10000 nm; and a dispersion medium which is composed of a poor solvent to the perovskite crystal particles, and in which the perovskite crystal particles are dispersed.
