Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement

open access: yesAdvanced Materials, EarlyView.
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Conductive Polymer Coatings Control Reaction Selectivity in All‐Iron Redox Flow Batteries

open access: yesAdvanced Materials, EarlyView.
Aqueous redox flow batteries are limited by the competing hydrogen evolution reaction (HER) at their negative electrodes. In this work, conductive polymers are conformally coated on porous carbonaceous electrodes to improve the reaction selectivity of hybrid all‐iron redox flow batteries.

Optimizing Perovskite Surfaces to Enhance Post‐Treatment for Efficient Blue Mixed‐Halide Perovskite Light‐emitting Diodes

open access: yesAdvanced Materials, EarlyView.
The halide postdeposition process is optimized by engineering blue mixed‐halide 3D perovskites with acetate‐rich surfaces. This engineered perovskite minimizes the washing effect of isopropanol, which slows down surface reconstruction and ultimately promotes the formation of a uniform mixed‐halide perovskite phase.
