Surface engineering is a known strategy to optimize the perovskite solar cells but it is usually based on weak bondings, such as Van der Waals, or coorordiating interacterions. Here He et al. report a chelation strategy using strongly adsorbed dithiocarbamate molecules and achieve high efficiency of 17.03% with excellent stability for CsPbI2Br based solar cells.
