PCBM, high quality electron accepting material for OPV devices

Enables rapid and efficient charge transfer and exciton dissociation

Specifications | Pricing and Options | MSDS | Literature and Reviews

PCBM, CAS number 160848-22-6, 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 [1], and has a high electron mobility [2].

PCBM from Ossila was used in the high-impact paper (IF 18.81)

PCBM from Ossila was used in the high-impact paper (IF 18.81), Towards Efficient Integrated Perovskite/Organic Bulk Heterojunction Solar Cells: Interfacial Energetic Requirement to Reduce Charge Carrier Recombination Losses, M. Daboczi et al., Adv. Funct. Mater., 2001482 (2022); DOI: 10.1002/adfm.202001482.

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.
