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.

Fully Bio‐Based Epoxy Resins from Liquefied Wood for Chemically Recyclable Wood Coatings

open access: yesAdvanced Functional Materials, EarlyView.
A bio‐based and chemically recyclable epoxy resin derived from liquefied wood and its use in wood coatings is presented. The resin exhibits mechanical, thermal, and water‐resistant properties comparable to commercial coatings and can be chemically recycled and reused. This approach provides fast access to glossy and fully biobased durable wood coatings

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.
