Strongly Anisotropic and Rapid Excitons Transport in Organic Crystal

open access: yesAdvanced Science, EarlyView.
The increased exciton diffusion length is beneficial to simplify device design and enhance photoelectric conversion efficiency. But the isotropic exciton diffusion may lead to reduced transport efficiency directed to the charge separation site. Here we have successfully achieved strongly anisotropic and rapid excitons transport in thienopyrrole ...

Self‐Sustaining Sensing Systems: Integration Strategies and Signal–Power Matching in Energy‐Harvesting Electronics

open access: yesAdvanced Science, EarlyView.
Energy‐harvesting‐integrated sensors couple ambient energy conversion with sensing, processing, and wireless communication. This review organizes recent progress through integration architectures and operating principles, revisiting co‐packaged, monolithic, and co‐functional designs together with always‐on, event‐driven, and multi‐modal sensing modes ...

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

open access: yesAdvanced 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.

Bioinspired Metastable Transient Peeling for Repeatable Rapid Release

open access: yesAdvanced Science, EarlyView.
Inspired by the explosive seed ejection of the squirting cucumber, this work introduces metastable transient peeling that temporally regulates stored interfacial energy release via a tunable energy barrier. A viscoelastic hemispherical gripper achieves 52 ms ultrafast, residue‐free release with 300 000‐cycle durability, enabling damage‐free handling of

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

open access: yesAdvanced 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 ...
