摘要： This composition for a hole collecting layer of an organic photoelectric conversion element contains: a charge-transporting substance comprising a polyaniline derivative represented by formula (1); a fluorine-based surfactant; and a solvent. The composition provides a thin film suitable for a hole collecting layer of an organic photoelectric conversion element, and is particularly suited for producing an inverse lamination type organic photoelectric conversion element. (In the formula, R1 to R6 each independently represent a hydrogen atom, etc., but one of R1 to R4 is a sulfonic acid group, one or more of the remaining R1 to R4 are a C1-20 alkoxy group, a C1-20 thioalkoxy group, a C1-20 alkyl group, a C2-20 alkenyl group, a C2-20 alkynyl group, a C1-20 haloalkyl group, a C6-20 aryl group, or a C7-20 aralkyl group, and m and n are numbers which satisfy 0≤m≤1, 0≤n≤1 and m+n=1.)

摘要： This carbon nanotube-containing thin film, which is formed on a base material, has a thickness of 10-500 nm. The ratio of coverage of the base material in a thin film forming portion by carbon nanotubes included in the thin film is 20-100%. The carbon nanotube-containing thin film exhibits a high ratio of coverage of the base material, despite having a thin film thickness, is capable of being ultrasonically welded, and, when used as an undercoat layer, is capable of achieving an energy storage device exhibiting low resistance.
