In our recent work, by introducing a thin modified layer of LiF or PbF2 to the interface between SnO2 and perovskite, a better interface has been realized to achieve an efficient perovskite solar cell. It is observed that with the help of the LiF or PbF2 modifying layer, the PVSC’s get a remarkable increase from 1.06V to 1.16 V in Voc and an enhancement in short current from 20.3 mAcm-2 to 21.8 mAcm-2. Our work highlights the importance of interface trap passivation and paves a new way to fabricate high performance PVSC with large Voc. |
