Wavelength and Pulsewidth Tunable Flexible CsPbBr3 Perovskite Microlasers by Mechanical Stress Modulation

open access: yesAdvanced Electronic Materials, EarlyView.
Mechanically tunable all‐organic CsPbBr3 perovskite microlasers on a flexible PET substrate is demonstrated, enabling simultaneous wavelength and pulsewidth modulation of laser emission. The strain–photon synergetic coupling mechanism is revealed.

Stability of PEA2PbBr4 Thin‐Film Photodetectors under Thermal and Moisture Stress

open access: yesAdvanced Electronic Materials, EarlyView.
This study investigates the environmental durability of 2D perovskite photodetectors under extreme heat and humidity. While pristine films degrade in harsh environmental conditions, adding a halogen‐bonding agent significantly improves stability. This passivated device maintains stable performance in conditions mimicking space and solar applications ...

Dry‑Contact Trimming for All‑Perovskite Tandem Solar Cells via Solid‑Solution Homogenization

open access: yesAdvanced Energy Materials, EarlyView.
Narrow‐bandgap Sn–Pb perovskites are promising bottom absorbers for all‐perovskite tandems but suffer from Sn‐rich surfaces and depth‐dependent lattice/compositional inhomogeneity. Layered‐perovskite‐assisted dry‐contact trimming removes Sn‐rich surface species and reconfigures the Sn–Pb absorber, enabling efficient charge collection, reduced voltage ...

Lattice Coherency‐Driven (111)‐Oriented Wide Bandgap Perovskite Films

open access: yesAdvanced Energy Materials, EarlyView.
Methylammonium lead chloride (MAPbCl3)‐derived seed templates regulate wide‐bandgap perovskite crystallization through coupled thermodynamic and kinetic effects. Lattice‐coherent templating lowers the energy cost for (111) epilayer growth, while growth retardation controls crystallization kinetics, ultimately producing highly crystalline face‐up (111 ...

Multiscale Perspectives on Perovskite Instability: From Atomistic Deformation to Device Degradation in Perovskite Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Multiscale perspectives on how excess charges in soft lead halide perovskites induce operational instability in photovoltaic devices are presented. Localized carriers formed under thermodynamic non‐equilibrium states modify atomistic interactions and drive lattice distortions, accelerating device degradation.
