报告内容简介🏃‍♀️‍➡️🚴🏻‍♂️：

he interfacial trap state passivation is acritical factor for achieving a state-of-the-art perovskite solar cells. In ourrecent work, by introducing a thin modified layer of LiF or PbF2 to theinterface between SnO2 and perovskite, a better interface has beenrealized to achieve an efficient perovskite solar cell. It is observed that withthe help of the LiF or PbF2 modifyinglayer, the PVSC’s get a remarkable increase from 1.06V to 1.16 V in Voc and anenhancement in short current from 20.3 mAcm-2 to 21.8 mAcm-2.Our work highlights the importance of interface trap passivation and paves anew way to fabricate high performance PVSC with large Voc.
