The development of organic semiconducting nanowires that act as charge carrier transport pathways in flexible and lightweight nano-electronics is a major scientific challenge. We report on the fabrication of fullerene nanowires that is universally applicable to its derivatives (pristine C$$_{60}$$, methanofullerenes of C$$_{61}$$ and C$$_{71}$$, and indene C$$_{60}$$ bis-adduct). Nanowires with radii of 8$$sim$$11 nm were formed via a chain polymerization reaction induced by a high-energy ion beam. Fabrication of a poly(3-hexylthiophene): [6,6]-phenyl C$$_{61}$$ butyric acid methyl ester (PC$$_{61}$$BM) bulk heterojunction organic photovoltaic cell including PC$$_{61}$$BM nanowires with precisely-controlled length and density demonstrates how application of this methodology can improve the power conversion efficiency of these inverted cells.
