It is demonstrated that the optical dynamics in MAPbI3 is primarily determined by the surface states. Pb dangling bonds in MAPbI3 introduce shallow electronic states, whereas rich-iodine surface of MAPbI3 induces deep trap centers for carriers which are detrimental to carrier lifetimes and diffusion lengths.
