TL;DR: Wang et al. realize smooth and pinhole-free, small-grained inorganic perovskite films with improved photoluminescence quantum yield by introducing trifluoroacetate anions to effectively passivate surface defects and control the crystal growth.

TL;DR: Methanesulfonate (MeS) is made use that can interact with the spacer BA cations via strong hydrogen bonding interaction to reconstruct the quasi-2D perovskite structure, which increases the energy acceptor-to-donor ratio and enhances the energy transfer in perovkite films, thus improving the light emission efficiency.

TL;DR: In this article, a hole injection layer (HIL) was introduced to improve the hole injection capability of NiO films and the resulting NiO HIL exhibits superior performance compared to the state-of-the-art poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonate) (PEDOT:PSS)-based QLEDs, with a maximum current efficiency and external quantum efficiency of 45.7 cd A(-1) and 10.5%, respectively.

TL;DR: In this article, a molecular modification strategy that simultaneously eliminates pinholes in perovskite layers by controlling the dynamics of film formation and passivates defects by incorporating Br species, thereby preventing shorts and non-radiative recombination was proposed.

TL;DR: In this article, the authors report on ultrastable CsPbBr3 nanocrystals (NCs) with a thick (∼25 nm) polymer coating prepared via an injection molding process.
