A new asymmetric benzothiadiazole based small organic chromophore for bulk heterojunction organic solar cells |
| 초록 |
This work illustrates the synthesis of donor-π-acceptor-donor (D1-π-A-D2), containing 2,1,3-benzothiadiazole as the electron-withdrawing core and dimethoxyphenyl as electron-donating terminal groups via suzuki cross-coupling reaction. The synthesized OMe-BBTz chromophore was used as donor material for the fabrication of bulk heterojunction organic solar cells (BHJ-OSCs). The presence of the ethylene moiety as a polyvalent spacer expanded the π-electron system in OMe-BBTz chromophore and improved the optical and structural properties. The morphology and the optical properties of the chromophore were studied to explain the performance of the fabricated BHJ-OSCs. The synthesized OMe-BBTz exhibited suitable HOMO and LUMO values of -5.8 eV and −3.9 eV, respectively, as calculated from cyclic voltammetry and the optical absorption onset. OMe-BBTz : PC61BM (1:3, w/w) active layer displayed the highest power conversion efficiency (PCE) of 3.53% %, the short circuit current (Jsc) of ∼8.71 mA/cm² with an open-circuit voltage (Voc) of ∼0.698V. |
