A Highly Stable Organic–Inorganic Hybrid Electron Transport Layer for Ultraflexible Organic Photodiodes

open access: yesAdvanced Materials, EarlyView.
Organic photodiodes (OPDs) with low dark current and stable detectivity under light irradiation, air exposure, and heating are realized using a nanoparticle‐based Zn‐chelated PEIE (PEI‐Zn NP) electron transport layer. This formulation effectively suppresses photocurrent degradation and dark current increase, ensuring enhanced environmental stability ...

A Natural Lignification Inspired Super‐Hard Wood‐Based Composites with Extreme Resilience

open access: yesAdvanced Materials, EarlyView.
Super‐hard wood‐based composites (WBC) are designed and developed inspired by the mesoscale homogeneous lignification process intrinsic to tree growth. This innovative hybrid structure is achieved by leveraging the infusion of low‐molecular‐weight phenol formaldehyde resin into the cell walls of thin wood slices, followed by a unique multi‐layer ...

Electron Extraction Optimization for Carbon‐Based Hole‐Conductor‐Free Perovskite Photovoltaics With Record 1.41 V VOC

open access: yesAdvanced Materials, EarlyView.
A gradient electron energy level strategy is constructed to reduce voltage losses in planar HTL‐free CsPbI2Br C‐PSCs. This electron extraction optimization enables rapid photogenerated electron extraction and carrier separation, thereby suppressing recombination at the back contact. The resulting PSCs deliver a record VOC of 1.41 V, a high PCE of 17.42%

Synthesis and Photothermal Processing of Silicon‐Based Nanoconfined MXenes

open access: yesAdvanced Materials Interfaces, EarlyView.
Intercalation of titanium carbide (Ti3C2Tx) MXenes with aminopropyl terminated polydimethylsiloxane (amino‐PDMS) is demonstrated through ion‐exchange method followed by photonic curing (PC) using xenon flashlamp. The intercalation and PC result in enhanced interlayer spacing of Ti3C2Tx of 13.5 and 11 nm, respectively. Furthermore, conversion of PDMS to
