Electron‐Beam Enables Spatially Resolved Defect‐Mediated Work Function Modulation in FAPbI3 Perovskite Thin Films

Advanced Science, EarlyView.
Electron‐beam irradiation enables defect‐mediated work function modulation in metal halide perovskites by regulating interstitial iodides. This approach allows continuous Fermi‐level tuning and spatially resolved formation of lateral surface‐potential‐defined junctions with built‐in potential.

Self‐Healing Ionogel Dual‐Network Enables Synergistic Defect Passivation and Strain Relief for High‐Efficiency Robust Perovskite Photovoltaics

Advanced Science, EarlyView.
PSCs are afflicted by inherent defects and lattice strain that limit PCE and stability. A cross‐linked multifunctional ionogel [HA‐AA][EMIES] is developed to modulate crystallization, relieve residual strain, and passivate defects, extending carrier diffusion length to over 8 µm and delivering PCEs of 26.45% for rigid devices and 25.14% for flexible ...

Multifunctional Ionic Liquid Enabling Cation Homogenization and Lead Chelation for Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
This work presents a multifunctional ionic liquid, [SO3H‐PMIm][OTf], that addresses A‐site cation inhomogeneity and lead toxicity in pure‐iodide wide‐bandgap perovskite solar cells. The additive enables homogeneous cation distribution, achieving 22.02% efficiency with 90% retention after 3000 h and reducing lead leakage by over 58%, thereby ...

Excitation‐Selective Hydrochromic Upconversion in Zero‐Dimensional Metal Halides

Advanced Science, EarlyView.
Excitation wavelength dictates whether moisture speaks. In zero‐dimensional metal halides, the same humidity leaves the upconversion emission unchanged under 980 nm excitation yet triggers a distinct green‐to‐red shift under 1550 nm. This excitation‐selective hydrochromism, governed by the absorption at each wavelength, enables stimulus‐dependent ...
