C60(OH)n , water soluble C60, polyhydroxylated fullerenes, or PC61BM, is a soluble derivative of fullerene C60 and one of the most widely used electron acceptor material in organic photovoltaic (OPV) devices.
PC61BM displays a high solubility in common solvents used with p-type organic polymers, allowing to produce ready to coat donor/acceptor ink formulations. With fast and efficient charge dissociation of excitons and high electron mobilities, efficient bulk heterojunctions active films can be manufactured using various coating methods.
