AB - A new synthetic route, to prepare an alkylated indacenodithieno[3,2b]thiophenebased nonfullerene acceptor (C8ITIC), is reported. Compared to the reported ITIC with phenylalkyl side chains, the new acceptor C8ITIC exhibits a reduction in the optical band gap, higher absorptivity, and an increased propensity to crystallize. Accordingly, blends with the donor polymer PBDBT exhibit a power conversion efficiency (PCE) up to 12.4%. Further improvements in efficiency are found upon backbone fluorination of the donor polymer to afford the novel material PFBDBT. The resulting blend with C8ITIC shows an impressive PCE up to 13.2% as a result of the higher opencircuit voltage. Electroluminescence studies demonstrate that backbone fluorination reduces the energy loss of the blends, with PFBDBT/C8ITICbased cells exhibiting a small energy loss of 0.6 eV combined with a high JSC of 19.6 mA cm−2.
