High Ambipolar Mobilities in OFETs Based on Dithienothiophene and Diketopyrrolopyrole |
| 초록 |
Donor-acceptor type conjugated polymer, PDTDP, containing dithienothiophene (DTT) and diketopyrrolopyrrole (DPP) was synthesized by stille polycondensation. The polymer showed small optical band gap of 1.42 eV in film and HOMO level of 5.09 eV. The change in crystallinity and morphology of the polymer were investigated with the various annealing temperatures through XRD and AFM. The OFETs in all annealing condition exhibited ambipolar transport properties and the highest values were reached to 1 cm2•V-1•S-1. According to the highly ambipolar characteristics, the polymer complementary inverters were fabricated and showed the output voltage gain over 25. PDTDP fabricated from blends with PC71BM also exhibited good performance in PSCs with a power conversion efficiency (PCE) of 4.45 %, a open-circuit voltage (VOC) of 0.67 V, a short-circuit current density (JSC) of 10.8 mA•cm-2, and a fill factor (FF) of 0.62 under AM 1.5G irradiation. |
