Abstract

Methylammonium lead iodide perovskite (MAPbI₃), as a new type of light absorber for optoelectronic devices, has attracted much interest and served as foundation for new device concepts. However, most studies to date are mainly focusing on the fabrication of MAPbI₃-based solar cells and photodetectors. Here we report a facile method to prepare a large-scale MAPbI₃ photocatalyst through atmospheric pressure physical vapor deposition. The photocurrent density of the MAPbI₃ coated with an Au layer can reach 30.8 and 85.5 μA/cm² in ethanol and H₂SO₄ electrolytes, respectively. Meanwhile, the strong interaction between H₂O orbitals and the conduction band of MAPbI₃ is revealed by density functional theory calculations. Our study opens a new pathway for the development of perovskite-based photo-electrochemical reaction systems.
