Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

Provided is a charge-transporting composition for forming a charge-transporting thin film for an organic photoelectric conversion element, the charge-transporting composition being ideal for the formation of a charge-transporting thin film for a photoelectric conversion element. In particular, when used as the hole transport layer of an inverted perovskite solar cell, this composition enables large improvement in hole transport layer formability and film stability when the film is left to stand in atmosphere, while maintaining the photoelectric conversion efficiency (PCE) of the resulting element at a high level. The charge-transporting composition comprises a nickel oxide precursor, a polymer compound, and a solvent.
