D18 is a next-generation wide-bandgap donor polymer for OPV. Record power conversion efficiencies of 18% have been published using this material in combination with the BTP-4F (Y6) nonfullerene acceptor. (1) Importantly, the D18:Y6 combination features low recombination probability and highly efficient exciton dissociations. (2)(3)
