제목 Synthesis and Characterization of Benzothiadiazole-Chromone End-capped Small Molecules for Organic Solar Cells
초록 The small molecule based on  A1-D-A2-D-A1 called BT-CMCN was synthetized and characterized as donor unit for organic solar cells. BT-CMCN consists of an electron deficient benzothiadiazole -BT (A2)- , electron-rich thiophene (D) and electron-deficient dicyanomethylene-4H-chromone -CMCN (A1)- moiety. BT-CMCN showed a broad absorption band at 400-800 nm with a optical band gap of 1.72 eV. The HOMO / LUMO energy level  were -5.29 eV and -3.58, respectively. Inverted-type organic solar cells (OSCs) based on BT-CMCN as donor and PC71BM as an acceptor were fabricated to evaluate BT-CMCN performance as a donor. The best performance exhibited a PCE of 0.69 % with short-circuit current density (JSC) of 2.03 mA/cm2, VOC of 0.79 V, and fill factor (FF) of 42.7%.
