Front Cover: Improving Moisture Proof and Heat Dissipation of Perovskite Solar Cells with Metal Oleate Passivation Layer (ChemSusChem 17/2025)

The Front Cover highlights a multifunctional passivation strategy for perovskite solar cells that uses europium oleate (Eu(OA)₃) coated on both top and side surfaces of the perovskite film. This layer effectively passivates the surface defects of the perovskite film, and improves the moisture resistance and heat dissipation of the film, thereby improving the photovoltaic performance and working stability of perovskite solar cells. More information can be found in the Research Article by Y. Xia, N. Kang, C. Wang and co-workers (DOI: 10.1002/cssc.202500196).
