Abstract
A charge transport varnish containing a charge transport substance, an electron-accepting dopant substance, and an organic solvent, wherein the electron-accepting dopant substance contains one or more types selected from naphthalene disulfonic acid, naphthalene trisulfonic acid, and naphthalene tetrasulfonic acid. This charge transport varnish is suitable for forming a hole collection layer that can be used to produce an organic photoelectric conversion element which exhibits high photoelectric conversion efficiency.
