Photovoltaic Switching Mechanism in Lateral Structure Hybrid Perovskite Solar Cells

Long range electromigration of methylammonium ions (MA+) in methyl ammonium lead tri‐iodide (MAPbI3) 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 p...

Description
Summary:Long range electromigration of methylammonium ions (MA+) in methyl ammonium lead tri‐iodide (MAPbI3) 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 MAPbI3 perovskite devices.
