Fluorinated isopropanol for improved defect passivation and reproducibility in perovskite solar cells
Nature Energy, Published online: 09 June 2025; doi:10.1038/s41560-025-01791-zThe passivation of surface defects is critical in perovskite photovoltaics yet challenging to implement in practice. Wang et al. show that fluorinated isopropanol allows the use of a high concentration of passivator molecules, ensuring the complete passivation of defects.
