| Popis: | 106 In this research, we synthesized a series of thienoisoindigo (TII)-based small molecules (H1-H7) and applied them to develop organic photovoltaics (OPVs). The TII-based small molecules use carbazole (H1), N-phenylcarbazole (H2, H4, H7), and 1,3-di(9H-carbazol-9-yl) benzene (H3), triphenylamine (H5, H7), benzene (H6) as electron donor (D), while TII as electron acceptor (A). Such D-A-D structure allowed the molecule to exhibit a strong intramolecular charge transfer such that they can absorb the light from visible and partially near-infrared (NIR) region. The bulk heterojunction (BHJ) solar cell device fabricated by using H2/PC61BM as the active layer exhibited a power conversion efficiency (PCE) of 0.82%, showing the potential of TII-based dyes for NIR organic photovoltaics (OPVs). |
