On the lead leakage concern of perovskite solar cells
Despite the remarkable progress on perovskite solar cells (PSCs), environmental concerns remain posted for the water dissolution of lead ions (Pb2+) from PSCs into eco-system. Therefore, it is highly desirable to make perovskites themselves robust enough to prevent the dissolution of Pb2+. In this report, an in-situ polymerization strategy will be introduced. The resultant perovskite-polymer hybrids enabled simultaneous enhancement on efficiency, stability and Pb2+ rejection rate, which may hopefully inspire future development of low-pollution PSCs.
Benfang Niu received his B.S. degree from Zhejiang University in 2019 and has been a Ph.D student in Department of Polymer Science and Engineering, Zhejiang University under the supervision of Prof. Chang-Zhi Li since 2019. His research interests focus on the additive/interface engineering of perovskite solar cells. Up to now, he has published an article in ACS energy letters titled ‘Mitigating the Lead Leakage of High-Performance Perovskite Solar Cells via In Situ Polymerized Networks’
