Abstract
A perovskite precursor solution which is capable of simultaneously forming a hole transport layer and a photoelectric conversion layer without forming a layer that inhibits transmission of electrons. A perovskite precursor solution includes a solvent; a perovskite precursor which forms a perovskite compound that performs photoelectric conversion; a hole transport layer forming compound which forms a self-assembled monolayer that has hole-selective permeability; and a fluorine-containing organic compound.
