Synthesis of Polybenzothiadiazole-co-dithienobenzodithiophenes (DTBDT) and Effect of Thiophene Insertion for High-Performance OPVs |
| 초록 |
Here we described the synthesis of novel donor-acceptor conjugated polymers with dithienobenzodithiophenes (DTBDT) as electron donor unit and 2,1,3-benzothiadiazole as electron acceptor unit for high performance OPVs. We studied the effects of strategically inserting thiophene to the DTBDT side position on opto-electronic performances of fabricated devices. From UV-Vis absorption, electro chemical and field effect transistor analyses, we found that thiophene-inserted DTBDT derivative can substantially increase the orbital-overlap area between adjacent conjugated chains and thus dramatically enhance charge carrier mobility, up to 0.55 cm2/Vs. The outstanding charge transport characteristic of this polymer allowed the realization of high performance organic solar cells with PCE of 5.1%. |
