Jinlong Cai's work on asymmetric nonfullerene acceptors is accepted in Advanced Functional Materials

    Jinlong Cai's work on asymmetric and halogenated nonfullerene electron acceptors for OPVs is accepted in Advanced Functional Materials.

    This work designed a series of fused-ring non-fullerene electron acceptor, and demonstrated the synergistic effect of Asymmetry and halogenation to tune the optoelectronic properties and enhance molecular stacking, leading to the highest device efficiency of 13.3% employing malononitrile (ClIC) unit terminated non-fullerene electron acceptor IDTT-Cl-2F.
