PCBM is a solubilised version of the buckminsterfullerene, C60, and is one of the most commonly used electron accepting materials in organic photovoltaic devices. The solubility enables PCBM to be dissolved in common solvents used for donor polymers, allowing the simultaneous casting of polymer and fullerene and the formation of an efficient bulk heterojunction. When used in a device with a donor polymer, PCBM enables rapid and efficient charge transfer and exciton dissociation [1], and has a high electron mobility [2].

The 99% purity PCBM is recommended for general OPV use, and the 99.5% purity PCBM is recommended for OFET applications where the highest crystallisation and mobility is required.
