Published: Oct. 29, 2020

Structural secrets of hybrid perovskites The optoelectronic and photovoltaic applications polycrystalline metal halide perovskite films are notable because grain boundaries in most materials cause scattering charge carriers that decreases performance. Electron microscopy studies these have been hindered by their rapid structural degradation under intense electron beams. Rothmann et al. now present an atomic crystallographic structure formamidinium lead triiodide (FAPbI 3 ) thin obtained low-electron-dose scanning transmission with advanced image processing. crystal sustains substoichiometry the A-site cation, has a nearly perfect alignment between PbI 2 impurity phases FAPbI perovskite, atomically clean domains. These features help to explain films' surprising regenerative ability, benign where strain dislocations appear mostly absent, why excess lead-iodide precursor can be counterintuitively beneficial.

ACS Energy Letters, Journal Year: 2023, Volume and Issue: 8(2), P. 1152 - 1191

Published: Jan. 26, 2023

Lead halide perovskite nanocrystals (LHP NCs) have emerged as next-generation semiconductor materials with outstanding optical and optoelectronic properties. Because of the high surface-to-volume ratio, performance colloidal stability LHP NCs largely depend on their surface chemistry, especially ligands termination. On one hand, capping improve luminescence; other hand highly dynamic binding nature is detrimental to photoluminescence NCs. In addition, functionalization desired molecules induces new functionalities such chirality, light harvesting, triplet sensitization through energy/electron transfer or use X-ray detectors. this review, we present current understanding an atomic view chemistry NCs, including crystal termination, vacancies, different types ligands.

Abstract Perovskite‐based light‐emitting diodes (PeLEDs) with a mixed halide composition can be used to obtain the “pure red” emission, i.e., in 620–650 nm range, required for high‐definition displays. However, fast ion migration induces phase separation these materials under electric fields, resulting poor spectral stability and low efficiency.
