Abstract

The electronic structure and surface composition of perovskite films after incorporation of different concentration of CsPbBr₃ nanocrystals (NCs) have been investigated with ultraviolet photoelectron spectroscopy (UPS) and X-ray, and angle-resolved photoelectron spectroscopy (XPS, AR-XPS). The electronic structure, surface composition and morphology of perovskite film have been changed through the interaction between CsPbBr₃ NCs and perovskite film. The band can be shifted upward by in incorporation of CsPbBr₃ NCs and it is independent of the concentration of CsPbBr₃ NCs. The surface component and its distribution can be adjusted by changing the concentration of CsPbBr₃ NCs and the proper concentration of CsPbBr₃ NCs would improve the stoichiometric ratio of perovskite film.
