Abstract
A new benzotriazole based π-conjugated polymer (Nap-UD-SiBTA) with siloxane-functionalized side chains is designed and synthesized for fabrication of non-fullerene organic solar cells (NFOSCs). The application of Nap-UD-SiBTA enhanced charge carrier mobility, good solubility and better surface morphology. The Nap-UD-SiBTA was synthesized by Stille polymerization and showed good compatibility with ITIC as non-fullerene acceptor. Therefore, Nap-UD-SiBTA blended with ITIC exhibited an efficiency of 4.76%, open-circuit voltage (V oc) of 0.77 V, a short-circuit current density (J sc) of 11.60 mA/cm2, and fill factor (FF) of 53.18%, respectively. The study results provide a pacesetting strategy to design and fabricate the highly efficient NFOSCs.
