摘要

Post-treatment is a widely used strategy to reduce defects in perovskite films,but has been largely limited to the solution phase. Herein, the posttreatmenttool kit and develop a universal amine salts (AIXI) vapor healing strategy bytaking advantage of the penetrating power of vapor and the soft-matter characteristicsof halide perovskite is expanded. In a striking demonstration, thepost-treatment of pristine perovskite layers allows simultaneous filling of theMA~+ and I~– vacancies, passivation of both the cation and anion defects, andhealing of the films to high order and high crystallinity required for high deviceperformance, from the surface to the bulk and all the way down to the bottom.Experiments and DFT calculations revealed that charge extraction can beenhanced and non-radiative recombination can be reduced by regulating theenergy levels and reducing the trap states via the A~IX~I vapor healing. Moreover,the diffusing A~IX~I can reach the NiO_x surface to obstruct the undesirable interfacialreactions and passivate the interface defects, further reducing the opencircuitvoltage (V_(oc)) loss. The vapor healing strategy substantially reduces thetrap density from 4.76 × 10~(15) to 1.04 × 10~(15) cm~(–3), and promots power conversionefficiency of the champion device from 17.92 to 20.48 with superiordevice consistency, V_(oc) up to 1.114 V and the operational device stability.
