제목 Effects of a Fluorinated Acceptor Polymer on the High-Performance of All-Polymer Photodetector Based on Diketopyrrolopyrrole-Quinoxaline
초록 All-polymer photodetectors (all-PPDs) show advantage in operational lifetime under thermal stress and blend-ratio resilience, which indicates stable organic photodetectors (OPDs). In this work, all-PPDs are developed based on bulk-heterojunction active layers which incorporate a donor polymer and a novel acceptor polymer on the applied linker units, namely 2,3-diphenyl-6,7-dicyanoquinoxaline for PD-T-Qx2CN and 2,3-bis(4-fluorophenyl)-6,7-dicyanoquinoxaline for PD-T-FQx2CN. we investigate the effects of the morphology of the photoactive layers on the dark current and the corresponding detectivity (4.63 × 1012 Jones for P3HT:PD-T-FQx2CN at -0.5V) by characterizing two different Conjugated polymers-based NIR OPDs. This contribution demonstrates a strategy of systematically tuning the polymeric structures to achieve high performance all-PPDs.
