Non-Fullerene Acceptors


Non-fullerene acceptors (NFAs) are a promising alternative to fullerene based electron acceptors. To a large extent, they have already taken the spotlight away from fullerene derivatives as the preferred acceptor in bulk-heterojunction organic solar cells (OSCs).

The discovery of ITIC in 2015 brought about the first serious challenge to the role of fullerenes as acceptors in polymer solar cells. With a greater degree of flexibility to tune the optical properties and electronic energy levels, ITIC based organic solar cells offer greater thermal and photochemical stability, longer device lifetimes, and higher power conversion efficiencies.

Easy synthesis

NFAs provide easy synthesis, with the possibility to tune energy levels - unlike fullerenes, which have limited energy-level tunability

Strong absorption

Non-fullerene have strong absorption in the visible region and good thermal stability (when compared to fullerenes with weak absorption)

Improved stability

Non-fullerene materials improve stability of bulk heterojunctions structural morphology in comparison to using traditional fullerene.

The performance of NFA-based devices has now overtaken that of their fullerene-based cousins, with recent non-fullerene organic solar cells (NFOSCs) reaching power conversion efficiencies of over 17%. More research is needed before devices can be created with efficiencies that rival those of inorganic devices, but with the development of new non-fullerene acceptor materials, the first OPV cells with efficiencies in excess of 20% could be on the horizon.

New low prices on all non-fullerene acceptors for organic solar cells with additional savings for large quantities. Order today.

We supply a range of the most promising n-type non-fullerene acceptors, including ITIC, N3, TPT10Y6 and Y7. We have a collection of intermediates and NFA monomers available for the synthesis of such ITIC non-fullerene acceptors. Our range currently includes 2HIC, 2FIC, 2ClIC, IDTB6-2CHO and IDTTB6-2CHO. Please contact us if you can't find what you are looking for.
