Lead Leaching of Perovskite Solar Cells in Aqueous Environments: A Quantitative Investigation

Abstract

Perovskite Solar Cells In article number http://doi.wiley.com/10.1002/solr.202200332, Meng Li, Bo Hou, Fei Wang, Zhe Li, and co‐workers reported a quantitative analysis of the Pb leaching dynamics by investigating five types of state‐of‐the‐art perovskite solar cells (PSCs). They found that Pb leaching occurs rapidly, with more than 60% of total Pb amount leaching within the first 120 s upon aqueous exposure. The Pb leaching rate is likely dependent upon the type of PSCs.
