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.

The Ideal

We propose a room-temperature scheme of ligand-promoted formation of high-quality perovskite films through the judicious design of nanostructured PbI2·(L)x intermediates, where L denotes the ligand. The mechanisms and features of the ideal ligand have been investigated through a combined experimental and theoretical study.
