Energy & Environmental Science

The diverse molecular stacking tuned by peripheral halogens in non-fullerene acceptors (NFAs) significantly affects the molecular physicochemical properties, the film morphologies and thus the power conversion efficiencies (PCEs) of organic solar cells (OSCs).

Peripheral halogenation engineering controls molecular stacking to enable highly efficient organic solar cells
