[60]Fullerene assembly films consisting of C-60 and 1,2-diaminoethane (ethylenediamine) were easily fabricated on an amino-group-modified substrate by an alternate immersion process. The C-60-assembly film was characterized after confirming the film formation using transmission absorption spectroscopy, transmission electron microscopy, atomic force microscopy, and X-ray photoelectron spectroscopy. An inverted-type organic solar cell was fabricated by using the C-60-assembly film as the acceptor layer in the photoactive layer of the solar cell. The resultant photoelectric conversion performances of the solar cells were evaluated using the photocurrent and photovoltage via the photoexcitation of polythiophene. The results suggested that the fabricated C-60-assembly film works as an n-type semiconductor for polythiophene.
