“…It is worth noting that RbF particles can be clearly identified aggregating at grain boundaries for the target film, which is beneficial to prevent moisture from directly diffusing into the perovskite film. 37 As presented in Figure 1c, the root-mean-square (RMS) roughness of the perovskite film after RbF modification significantly reduces from 31.68 to 15.57 nm, and the smoother surface can facilitate the interfacial charge transport to the HTL. 38 We carried out XRD measurements to determine the crystal phase of the obtained perovskite films.…”

“…SEM-EDS and elemental mapping images preliminarily reveal the existence of Rb and F elements on the surface of RbF-modified films (Figure S1). It is worth noting that RbF particles can be clearly identified aggregating at grain boundaries for the target film, which is beneficial to prevent moisture from directly diffusing into the perovskite film . As presented in Figure c, the root-mean-square (RMS) roughness of the perovskite film after RbF modification significantly reduces from 31.68 to 15.57 nm, and the smoother surface can facilitate the interfacial charge transport to the HTL .…”
