TL;DR: In this article, a dimensionally graded perovskite formation approach was proposed to reduce the photovoltage loss through the simultaneous passivation of internal bulk defects and dimensional graded two-dimensional pervskite interface defects.

TL;DR: In this paper , the origins and influences of metallic lead impurities in halide perovskites were investigated and a strategy for avoiding the formation of detrimental Pb⁰ byproducts was proposed.

TL;DR: This work elaborately develops chlorine binding on the surface of tin oxide electron transport layer for high open-circuit voltage device (1.195 V) and enhances the binding of chlorine with lead at the SnO2/perovskite interface, which will promote efficient electron transfer at the interface.

TL;DR: In this paper, the authors proposed an interfacial engineering strategy to form a 2D/3D perovskite heterojunction using 2-thiopheneethylammonium chloride (TEACl).

TL;DR: In this article , an internal encapsulation strategy by introducing NbCl5 at the buried tin oxide/perovskite interface and spin-casting n−butylammonium bromide on top of perovskites is developed to comprehensively passivate the vacancies and hence block the channels for ion diffusion or migration.
