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.
