dc.description.abstract | This paper mainly discusses the structure-property relationship of two donor-acceptor-donor (D–π–A–π–D) type dopant-free hole transporting materials (HTMs) (TPA-TPy and TPA-Py-PTZ) comprising primarily of 2,4,6-trisubstituted pyridine as the acceptor core and 4,4′-dimethoxytriphenylamine as the peripheral donor groups and their use in p-i-n perovskite solar cells (PVSCs). Compared to inferior TPA-Py-PTZ, TPA-TPy has a superior hole extraction and hole transport at the HTM/perovskite interface. The pinhole-free, smooth and dense, fully covered and well-crystallized MAPbI3 perovskite layer on TPA-TPy reduces the carrier recombination and substantially improves the short circuit current density (JSC), open circuit voltage (VOC), and the fill-factor (FF) of MAPbI3 PVSCs. The PVSC employing TPA-TPy as HTM exhibits a power conversion efficiency (PCE) of 15.33% with a JSC of 23.69 mA cm?2, a VOC of 0.95 V, and a FF of 68.10%. Especially, both TPA-TPy and TPA-Py-PTZ PVSCs exhibit a better moisture stability than that of NiOx PVSCs. It is because of the hydrophobic nature of TPA-TPy and TPA-Py-PTZ, which enables the formation of MAPbI3 perovskite layer having a larger grain-size, a less grain boundary, and a less infiltration of moisture. ? 2022 Elsevier B.V. | - |
