Iodide-ion conduction in methylammonium lead iodide perovskite: some extraordinary aspects

Abstract

A recent model of iodide-ion conduction in methylammonium lead iodide perovskite (CH3NH3PbI3) is discussed. Issues include the low activation barrier of vacancy migration and the high diffusivities of iodine vacancies and interstitials. Comparisons are also made with the behaviour of point defects in the oxide perovskite SrTiO3.
