Enhancing Indoor Photovoltaic Efficiency to 37.6% Through Triple Passivation Reassembly and n‐Type to p‐Type Modulation in Wide Bandgap Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Triple Passivation Treatment (TPT) strategy enables 1.75 eV wide‐bandgap perovskite solar cells (WB‐PSCs) with suppressed halide phase segregation and n‐to‐p type surface transition. The photoluminescence quantum yield increases from 0.5 to 2.1%, indicating reduced non‐radiative losses.

High‐Performance Millimeter Scale Electromagnetic Generator

open access: yesAdvanced Functional Materials, EarlyView.
A high‐performance millimeter‐scale electromagnetic generator (mmEMG) is developed using magnetic flux concentrator (MFC) films on both coil ends to enhance magnetic flux. Through simulations and experiments, structural and magnetic properties are optimized, achieving a 5.6‐fold electrical output improvement.

GWRF: A Generalizable Wireless Radiance Field for Wireless Signal Propagation Modeling [PDF]

open access: yesarXiv
We present Generalizable Wireless Radiance Fields (GWRF), a framework for modeling wireless signal propagation at arbitrary 3D transmitter and receiver positions. Unlike previous methods that adapt vanilla Neural Radiance Fields (NeRF) from the optical to the wireless signal domain, requiring extensive per-scene training, GWRF generalizes effectively ...

Phase Engineering of a 1D van der Waals Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
Explores the transformative potential of 1D van der Waals materials, focusing on the monoclinic‐to‐tetragonal phase transition in NbTe4, its atomic‐scale mechanisms, and significant metal‐insulator transition (MIT) behavior. Highlights advanced imaging insights and the applications of reversible phase transitions in memory devices, sensors, and ...
