Non-fullerene acceptors (NFAs) are a promising alternative to fullerene-based electron acceptors.
When compared to fullerenes, NFAs have strong absorption in the visible region and good thermal stability
Non-fullerene materials improve stability of bulk heterojunctions structural morphology
We supply a range of the most promising n-type non-fullerene acceptors, alongside a collection of intermediates and NFA monomers for the synthesis of ITIC non-fullerene acceptors.

The discovery of ITIC in 2015 brought about the first serious challenge to the role of fullerenes as acceptors in polymer solar cells. 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).
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.
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.
