PCBM (CAS number: 160848-22-6), in its full form, is [6,6] phenyl-C61-butyric acid methyl ester. The butyric acid methyl ester and phenyl substituents indicate that it is a solubilized version of buckminsterfullerene (C60).
PCBM is one of the most commonly used electron-accepting materials in organic photovoltaic devices. It is also used as an electron-transport material in bulk-heterojunction perovskite–PCBM solar cells. The solubility of PCBM in common solvents used for donor polymers enables simultaneous casting of polymer and fullerene, forming 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 exhibits 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 crystallization and mobility is required. The old product code M111 is upgraded to M0111.
