N2 - While dual-acceptor-type conjugated polymers have witnessed a great success in organic field-effect transistors (OFETs), their potential multifunctionality in other optoelectronic devices has been overlooked. Herein, three conjugated polymers (DPPF-BDD, DPPT-BDD, and DPPSe-BDD) comprising furan/thiophene/selenophene-flanked diketopyrrolopyrrole (DPP) and dioxo-benzodithiophene (BDD) as repeating units are designed, synthesized, and characterized. Modulating the chalcogen on DPP flank shows an impact on dual-acceptor polymer optoelectronic properties. Subsequently, the potential of these polymers in both OFETs and perovskite solar cells (PSCs) either as semiconductors or as passivation materials, respectively, is investigated. Interestingly, DPPF-BDD, DPPT-BDD, and DPPSe-BDD show ambipolar behavior in vacuum with hole (μh) and electron (μe) mobilities of 0.0263/0.0223, 0.0187/0.0123, and 0.0070/0.0051 cm2 V−1 s−1, respectively. Upon doping tetrabutylammonium iodide into DPPF-BDD, DPPT-BDD, and DPPSe-BDD polymers, the respective OFETs show relatively higher μh and μe (0.0389/0.0503; 0.0289/0.0259; 0.0058/0.0156 cm2 V−1 s−1) than the undoped polymer OFETs. Furthermore, DPPF-BDD-, DPPT-BDD-, and DPPSe-BDD-incorporated (in the antisolvent treatment and PCBM electron transport layer) PSCs display maximum power conversion efficiency of 23.48%, 22.85%, and 23.35%, respectively, surpassing the control device (22.83%), which is benefited from the perovskite surface passivation and the charge extraction improvement. Overall, a new class of multifunctional DPP-based dual-acceptor-type polymers that are highly compatible with OFETs and high-performance PSCs is presented.
