Understanding and controlling defect generation and movement in organic‐inorganic lead halide perovskite materials will not only lead to more stable devices but also new device concepts. In article number 1700527 , Wei D. Lu and co‐workers reveal the formation, migration and annihilation of iodine vacancies in CH 3 NH 3 PbI 3 films under an electric field and/or light illumination. An electric‐write and light‐erase memory device is demonstrated.
