Non-fullerene acceptors with hetero-dihalogenated terminals induce significant difference in single crystallography and enable binary organic solar cells with 17.5% efficiency

Despite the dihalogenation of terminals being an effective strategy to produce efficient nonfullerene acceptor (NFA)-based organic solar cells (OSCs), hetero-dihalogenated terminals are quite difficult to prepare. Here, we synthesized, for the first time, two new hetero-dihalogenated terminals ( FCl...
