PCBM: PC61BM

PCBM: PC71BM

[6,6]-Phenyl C71 butyric acid methyl ester, or PC71BM is a solvent soluble derivative of fullerene C70 and one of the most widely used electron acceptor n-type material in organic photovoltaic devices.

With a great solubility in common solvents, PC71BM can be blended at high concentration with many p-type polymers or single molecules. Ready to coat inks can be formulated and used in electronic devices adopting organic thin film architectures.

Promoting exciton dissociation and fast, efficient charge transfers, PC71BM usage results in higher OPV performances.

Mainly due to a change in geometry from a spherical core (C60) to an oval core (C70), PC71BM absorbes more efficiently than PC61BM in the visible spectrum, contributing to an overall greater film absorption, increasing OPV output by up to 25%.

PCBM: bis-PC62BM

[6,6]-Phenyl C62 butyric acid methyl ester, or bis-PC62BM is a solvent soluble derivative of fullerene C60 and one of the most widely used electron acceptor n-type material in organic photovoltaic devices.

With a great solubility in common solvents, bis-PC62BM can be blended at high concentration with many p-type polymers or single molecules. Ready to coat inks can be formulated and used in electronic devices adopting organic thin film architectures.

Promoting exciton dissociation and fast, efficient charge transfers, bis-PC62BM usage results in higher OPV performances.

The higher number of side groups favours higher solubilities than the mono-derivative. Being a mix of positional isomers, it also helps controlling phase separation during film annealing.
