Liwei'papers are accepted by Joule and Advanced Functional Materials.

    Liwei's work on controlling the molecular order and orientation of non-fullerene electron-acceptors in their photovoltaic blends are accepted in high-profile journals of Joule and Advanced Functional Materials. H- and J- type pi-pi stacking are found critical to broaden the absorption spectrum of non-fullerene acceptor and contribute to improved device efficiency.
