PCBM is the common abbreviation for the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester. It is being investigated in organic solar cells.[1]

PCBM is a fullerene derivative of the C60 buckyball that was first synthesized in the 1990s by Fred Wudl's group.[2] It is an electron acceptor material and is often used in plastic solar cells or flexible electronics in conjunction with electron donor materials such as P3HT or other polymers. It is a more practical choice for an electron acceptor when compared with fullerenes because of its solubility in chlorobenzene. This allows for solution processable donor/acceptor mixes, a necessary property for "printable" solar cells. However, considering the cost of fabricating fullerenes, it is not certain that this derivative can be synthesized on a large scale for commercial applications.
