| 英文摘要 | A readily available small molecular hole-transporting material (HTM), OMe-TATPyr, was synthesized and tested in perovskite solar cells (PSCs). OMe-TATPyr is a two-dimensional pi-conjugated molecule with a pyrene core and four phenyl-thiophene bridged triarylamine groups. It can be readily synthesized in gram scale with a low lab cost of around US$ 50g(-1). The incorporation of the phenyl-thiophene units in OMe-TATPyr are beneficial for not only carrier transportation through improved charge delocalization and intermolecular stacking, but also potential trap passivation via Pb-S interaction as supported by depth-profiling XPS, photoluminescence, and electrochemical impedance analysis. As a result, an impressive best power conversion efficiency (PCE) of up to 20.6% and an average PCE of 20.0% with good stability has been achieved for mixed-cation PSCs with OMe-TATPyr with an area of 0.09 cm(2). A device with an area of 1.08 cm(2) based on OMe-TATPyr demonstrates a PCE of 17.3%. |
