Summary: By adding excessive ligand combinations, the phase distribution of quasi-2D perovskite can be redistributed and the high-order phase can be inhibited, realizing spectrally stable pure red perovskite light-emitting diodes (PeLEDs). The appropriate excess organic ligands do not affect charge injection but maintain efficient energy funneling and passivate the defect. The narrowed phase distribution reduces the band tail state and restrains reverse charge transfer, resulting in enhanced radiation recombination. We achieved efficient and spectrally stable pure red PeLEDs operating at 638 nm (approaching the Rec. 2020 specification) with a peak EQE of 11.8% and a maximum luminance of 1688 cd/cm2. This study provides guidance for future developments of highly efficient pure red PeLEDs.

Summary: The electronic and spatial effects of the molecular additives methyl, hydrogen, and hydroxyl groups substituted the diphenyl phosphine oxygen additives were systematically studied. It was found that the hydroxyl group-substituted diphenylphosphinic acid (OH-DPPO) exhibited the best defect passivation ability due to its electron-donating conjugation effect and moderate steric hindrance. Additionally, the hydrogen bonding between the hydroxyl group and Br suppressed ion migration. The OH-DPPO passivated devices achieved an external quantum efficiency of 22.44% and a 6-fold improvement in lifetime.

Summary: Oxygen ingression has been shown to decrease the carrier lifetime of Sn-based perovskites, and our calculations reveal that oxygen tends to form substitutional OI, which remarkably increases the recombination rate of native I vacancies (VI). This explains the observed decline of carrier lifetime in perovskites exposed to air. The enhanced carrier recombination is due to a smaller electron capture barrier of OI, resulting from lattice strengthening and suppressed structural relaxation upon electron capture. These insights offer a route to improve device performance in Sn-based perovskite optoelectronics operating in ambient air.

Summary: Hybrid organic-inorganic perovskites have potential in circularly polarized light source applications with chirality. Circularly polarized photoluminescence is important for investigating the chiroptical properties of perovskites. However, further research is needed for optimization. Chiral ligands can influence the electronic structure of perovskites, increasing asymmetry and emitting circularly polarized photons. Modifying with chiral amines leads to passivation of film defects, enhancing radiation recombination and emitting more circularly polarized photons. This approach offers the possibility of fabricating and refining circularly polarized light-emitting diodes.

Summary: A crystal growth kinetic regime called oriented attachment (OA) has been discovered for tin halide perovskites (THPs), which allows the fabrication of high-quality THP films for optoelectronic devices. By tuning the surface energy using 2-phenoxyethylamine bromide (POEBr), highly oriented FASnI3-POEBr perovskite films are obtained. The OA growth kinetics reduces the crystal growth rate and enables the formation of dense, smooth, and oriented THP films, resulting in an impressive efficiency of over 14%.
