제목 Synthesis and Characterization of Small Molecules based on Benzothiadiazole as the core and its Application in Organic Solar Cells
초록 Small molecule acceptor materials with A1-π-A2-π-A1 (acceptor1-π-acceptor2-π-acceptor1) type of structure 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), have been synthesized. The materials showed good thermal stability with the onset decomposition temperature (Td) upon 310 °C at 5 wt % loss. BT-T-IDC material has a low solubility due to its high planarity structure. In order to increase the solubility of BT-T-IDC material, t-butyl was introduced into the material. As the result, the PCE of the device based on the material with t-butyl (BT-T-tB-IDC) (1.55%) was 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%.
