Computational chemistry-assisted design of a non-fullerene acceptor enables 17.4% efficiency in high-boiling-point solvent processed binary organic solar cells

A new non-fullerene acceptor, namely BOEH-4Cl, was computational chemistry-assisted designed and synthesized. Paired with polymer donor PM6, the high-boiling-point solvent processed binary BOEH-4Cl-based OSCs exhibit a best efficiency of 17.4%.
