Title: Photovoltaic switching mechanism in lateral structure hybrid perovskite solar cells

In this study, long range electromigration of methylammonium ions (MA +) in methyl ammonium lead tri-iodide (MAPbI 3) film is observed directly using the photo­thermal induced resonance technique. The electromigration of MA + leads to the formation of a lateral p-i-n structure, which is the origin of the switchable photovoltaic effect in MAPbI 3 perovskite devices.
