Fig. 2

Evolution of GD-OES elemental depth profiles. a–c lead (Pb) and d–f sulfur (S) in the CsFAPI/AKC perovskite precursor layer upon spin coating (sputtering erosion from top to bottom). The interface between the upper and lower layers is indicated by a dashed line on each profile. Absolute values of the area under the curve delimited by each layer are shown for Pb (g) and S (h) and the numbers indicate the relative contributions of the layers to the total area under the curves. Source data are provided as a Source Data file.
