Abstract: Polyaniline (PANI)-C60 composites film was prepared by liquid-state mixture of PANI and C60 solutions. The interaction between polyaniline emerald base and C60 were investigated and explained according to the results of FTIR spectroscopy. The improvement of crystallinity of PANI-C60 composites was evaluated by using X-ray diffraction spectra (XRD). The mechanism of charge transport in these composites was also studied. The photoconductivity of PANI-C60 composites film was enhanced markedly and photoluminescence spectra (PL) intensity decreased greatly, which take the photoinduced charge transfer between PANI and C60 into consideration.

Key words: Polyaniline, C60, Composites, Photoccurrent, Photovoltaic effect
