摘要

Electrically driven reversible structural conversion between the MAPbI₃ and PbI₂ phase in MAPbI₃ at 330 K is first reported, which provides insights into the intrinsic stability and chemical activities of MAPbI₃ materials. Meanwhile, direct visualization of the macroscopic migration of iodine anions is also reported for the first time, which provides strong evidence for the iodine ions migration.
