    ABSTRACT

    To mitigate the strong aggregation and limited solubility observed in the previously reported vinylene‐bridged alkoxyfluorobenzothiadiazole (FOBTzE)‐based polymer, PFOE4T, we designed and synthesized PBFOE‐1. This novel semiconducting polymer, based on the FOBTzE framework, incorporates an alkylthienyl‐substituted benzodithiophene (BDT) as the donor unit. PBFOE‐1 demonstrated broad and intense absorption between 300 and 700 nm with a relatively wide bandgap of 1.7 eV. Additionally, PBFOE‐1 features a low HOMO energy level (−5.43 eV) compared to PFOE4T (−5.23 eV), likely due to the incorporation of weakly electron‐donating BDT into the polymer backbone. While the PFOE4T/Y12‐based solar cell yielded a modest power conversion efficiency (PCE) of 4.37%, characterized by a short‐circuit current density (Jsc) of 13.5 mA cm−2, an open‐circuit voltage (Voc) of 0.69 V, and a fill factor (FF) of 0.47, the PBFOE‐1/Y12 cell exhibited a substantially higher PCE of 10.96%. This improvement is reflected in the enhanced Jsc (23.23 mA cm−2), Voc (0.84 V), and FF (0.56). The superior performance of PBFOE‐1 is primarily attributed to its improved solubility and aggregation behavior, promoting a more ordered face‐on orientation and optimal blend morphology.
