DESCRIPTION
General description
[6,6]-Phenyl C61 butyric acid methyl ester ([60]PCBM) is a methanofullerene that has a better diffusion in organic molecules than fullerenes (C60). It has high electron mobility, which allows it to be used as an electron acceptor in major electrochemical applications.

PCBM, high quality electron accepting material for OPV devices
Enables rapid and efficient charge transfer and exciton dissociation
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, and has a high electron mobility.
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.
PCBM is the common abbreviation for the fullerene derivative, phenyl-C61-butyric acid methyl ester and is one of the most commonly used electron-accepting materials in organic photovoltaic devices.
It is commonly used in flexible plastic or electronic solar cells in conjunction with an electron donor material such as P3HT (SOL4106), PCDTBT (SOL4280), or PTB7 (SOL4700) to make high Open Circuit Voltage (Voc), high Power Conversion Efficiency (PCE) bulk heterojunction solar cells, >99.9% isomerized.
It is a more practical choice for being an electron acceptor when compared to fullerenes due to its solubility in chlorobenzene. This allows for processable donor/acceptor solution mixtures, a necessary property for “printable” solar cells.
