Abstract

Damp-Heat Stability in Perovskite Solar Cells In their Research Article (DOI: 10.1002/advs.202521825), Dong Suk Kim, SeJin Ahn, and co-workers report a redox-catalytic strategy for damp-heat stable perovskite solar cells using micro-sized NiOx powders. This catalyst facilitates the p-doping of Spiro-OMeTAD while effectively capturing and removing Li+ ions, successfully demonstrating a “tBP-free” and “Li+-free” hole transport layer.
