Fullerene assembly films consisting of C60 and 1,2-diaminoethane (ethylenediamine) were fabricated on an amino-group-modified substrate and were characterized. An inverted-type organic solar cell was fabricated using the C60-assembly film as the acceptor layer in the photoactive layer of the solar cell. The resultant photoelectric conversion performances of the solar cells were studied using the photocurrent and photovoltage via the photoexcitation of polythiophene. Controlling the energy levels of the C60-assembly film and optimizing the thickness of each layer in the solar cell may play an important role in obtaining efficient photoelectric conversion properties and organic electronic materials. The fabricated C60-assembly films may accelerate the development of organic photoelectric conversion devices as novel n-type fullerene-based materials and organic electronic materials.
