Abstract
This hole collection layer composition for an organic photoelectric conversion elements comprises: a charge-transporting substance formed of a polyaniline derivative represented by formula (1); fluorochemical surfactant; metal oxide nanoparticles; and a solvent. The hole collection layer composition provides a thin film having excellent adhesiveness to an active layer of an organic photoelectric conversion element. {R-Rare each independently a hydrogen atom, a halogen atom, a nitro group, a cyano group, a sulfonic acid group, a C-Calkoxy group, a C-Cthioalkoxy group, a C-Calkyl group, etc. Meanwhile, one of R-Ris a sulfonic acid group and at least one of the remaining R-Ris a C-Calkoxy group, a C-Cthioalkoxy group, a C-Calkyl group, etc., and m and n are numbers that satisfy 0≤m≤1, 0≤n≤1, and m+n=1.}
