在这项研究中,使用光热诱导共振技术直接观察到甲基铵三碘化铅(MAPbI3)薄膜中甲基铵离子(MA+)的长程电迁移。 MA+的电迁移导致横向p-i-n结构的形成,这是MAPbI3钙钛矿器件中可切换光伏效应的起源。
In this study, 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.
