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.


[60]PCBM is an n-type semi-conductor widely used as an a electron transport material with low cost and high surface area in different energy based applications like organic photovoltaics (OPVs), perovskite solar cells (PSCs), organic field effect transistors (OFETs) and photodetectors.

Soluble n-channel organic semiconductor. For use as an n-type layer in plastic electronics, especially bulk heterojunction OFETs and photovoltaic cells (PVs).
