Herein, performance is significantly improved by engineering CsPbI3-x Brx films 2-mercapto-1-methylimidazole (MMI). It found mercapto group can preferably react undercoordinated Pb2+ from forming Pb-S bonds, which appreciably reduces surface trap density. Moreover, MMI modification results in a better alignment electron-transporting material, promoting carrier transfer reducing voltage deficit.

Inverted CsPbI3 commonly exhibits a more p-type surface than bulk, which induces severe interfacial recombination and, thus, limits the device's Voc and efficiency in inverted perovskite solar cells (PSCs). Here, gradual CsPbI3/PbS heterojunction is constructed to inhibit such through situ chemical sulfidation with N,N′-diphenylthiourea (DPhTA). DPhTA can directly react form PbS induce p- n-type transition at surface, leads energy level bending downward establishing top of region.
