Fullerenes for Photovoltaics and Biotechnology

About

Fullerenes are allotropes of carbon that are closed shells and have a similar structure to footballs / soccer balls. The discovery of buckminsterfullerene, also known as C 60 fullerene , sparked the creation of a series of related molecules. Fullerenes have unique properties that make them suitable for use in electronics. Fullerene acceptors, also known as fullerene-based acceptors or acceptor molecules, are a type of electron acceptor material commonly used in conjunction with organic donor materials. Features of Fullerenes Electron acceptance: Fullerenes have excellent electron accepting properties. They readily accept electrons from donor materials. This helps to facilitate efficient charge separation in organic solar cells. Solubility: Many fullerene acceptors are soluble in common organic solvents, making them compatible with solution processing techniques, including spin coating. High electron mobility: This allows for efficient electron transport within the acceptor material, which is crucial for achieving high device performance. Explore our fullerenes, soluble fullerene derivatives, and fullerene replacements for electron acceptors in OPV devices and n-type interfaces in perovskite solar cells. Fullerene derivatives, based on the classic fullerenes C 60 and C 70 , are functionalized with chemical groups including phenyls and esters. This makes derivatives like PCBM easier to process within your device.
