Benzothiadiazole-based End-capped with Dicyanovinylindandione Small Molecule and their photovoltaic properties |
| 초록 |
A series of small molecule acceptor materials with the architecture of A1-π-A2-π-A1 (acceptor1-π-acceptor2-π-acceptor1) have been synthesized. The material structures are based on benzothiadiazole (BT) (A2) as the conjugated backbone, electron-rich thiophene (D) as the π-bridge, and end-capped by dicyanovinylindandione (IDC) (A1) groups, which are (BT-T-IDC) and (BT-T-tB-IDC). Both materials showed good thermal stability with the onset decomposition temperature (Td) upon 310oC at 5 wt % loss. However, BT-T-IDC material has poor solubility due to its high planarity structure. To increase the solubility of BT-T-IDC material, t-butyl is introduced into the end-capped moiety structure. As the result, the PCE of the device based on the material with t-butyl (BT-T-tB-IDC) (1.55%) was significantly enhanced than that of the device based on BT-T-IDC with an open-circuit voltage (VOC) of 0.88 V, a short-circuit current density (JSC) of 4.09 mA/cm2, and a fill factor (FF) of 43.0%. |
