报告人简介： Prof. Yiqiang Zhan obtained his Ph.D. in physics from Fudan University, China in 2005 before moving to ISMN-CNR bologna, Italy as a postdoc. From 2007, he continued his research in Linkoping University, Sweden initially as a postdoc and then as an assistant professor. He joined Fudan University as an associate professor at 2011 and has been promoted to Professor at 2016. He has authored and co-authored over 70 peer-viewed journal articles, with a google scholar H-index of 23. His research interests include flexible electronics, smart electronics, material physics. 报告内容🧛🏽： The interfacial trap state passivation is a critical factor for achieving a state-of-the-art perovskite solar cells. 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. |
