This method for producing a charge transporting thin film, wherein a charge transporting varnish containing a charge transporting substance, an electron accepting dopant substance containing at least one substance selected from among naphthalene sulfonates and benzene sulfonates, and an organic solvent is applied onto a substrate and is subsequently heated at 100-180° C. so that the organic solvent is evaporated therefrom, is capable of efficiently producing a charge transporting thin film which is able to be used as a hole collecting layer that enables the achievement of an organic photoelectric conversion element having high photoelectric conversion efficiency.
A method for producing a charge transporting thin film, comprising applying a charge transporting varnish containing a charge transporting substance, an electron accepting dopant substance containing at least one kind selected from naphthalenesulfonic acid and benzenesulfonic acid, and an organic solvent on a substrate and heating the charge transporting varnish at 100° C. to 180° C. to evaporate the organic solvent.
A charge transporting varnish comprising a charge transporting substance;
