Fluorinated Methylammonium Cation Containing Perovskite Solar Cells With Over 25% Power Conversion Efficiency

open access: yesAdvanced Energy Materials, EarlyView.
Fluoromethylammonium iodide (FMAI) is prepared using a facile procedure through a simple nucleophilic reaction between fluoroiodomethane and ammonia in methanol and tested in n‐i‐p perovskite solar cells. FMA+ cation in combination with FA+ and Cs+ cations affords a power conversion efficiency close to 26% with a long‐term operational stability for ...
