Synthesis and Characterization of a series of Low-Bandgap Copolymers based on DTBDT for High-Performance Organic Photovoltaic Solar Cells |
| 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 power conversion efficiency (PCE) of up to 5% were achieved under AM 1.5G simulated solar light. |
