在这里，我们在MAPbI3的机械化学合成过程中加入BMIMBF4。基于详细的光致发光和电学测量，我们证明了钝化的粉末颗粒中的缺陷，也导致抑制离子迁移。
Here we add BMIMBF4 during the mechanochemical synthesis of MAPbI3. Based on detailed photoluminescence and electrical measurements, we demonstrate a passivation of defects in the powder pellets that also leads to a suppression of ion migration.
