When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Path‐Decoupled Cation‐Eutaxy III–V van der Waals Memristive Semiconductors for Mitigating the Neuromorphic Accuracy‐Energy Trade‐off

open access: yesAdvanced Materials, EarlyView.
Path‐decoupled III–V van der Waals memtransistors spatially separate ionic and electronic transport to overcome the conventional trade‐off between accuracy and energy in neuromorphic hardware. Mobile K+ ions in the vdW gaps set a wide conductance window, Gmax/Gmin, while gate‐tunable hole conduction lowers programming energy, enabling reliable ...

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

open access: yesAdvanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Wafer‐Scale 2D High‐Entropy Transition Metal Dichalcogenide Thin‐Film Catalysts for Efficient and Durable Photoelectrochemical Hydrogen Production

open access: yesAdvanced Materials, EarlyView.
A wafer‐scale 2D high‐entropy (MoWTaNbRu)S2 thin‐film catalyst with a distorted 1T phase integrated onto p‐Si photocathode is designed for highly efficient and durable photoelectrochemical hydrogen evolution reaction. The high‐entropy effect in layered transition metal dichalcogenides optimizes hydrogen adsorption energetics, accelerates photogenerated

Economic Low‐Carbon Chemical Production via Paired Electrolysis of Carbon Monoxide (CO) and 5‐hydroxymethylfurfural (HMF)

open access: yesAdvanced Materials, EarlyView.
Replacing CO2 with CO at the cathode and integrating a catholyte‐layer membrane electrode assembly transforms paired electrolysis into a stable platform for co‐producing ethylene and 2,5‐furandicarboxylic acid. Combined experimental and techno‐economic analyses identify carbon monoxide and 5‐hydroxymethylfurfural as the most compatible pairing ...

Plasma‐Sequence‐Engineered Atomic Layer Deposition of Ultra‐Thin SiNx for Enhanced Etching Resistance in Extreme Ultraviolet Pellicles

open access: yesAdvanced Materials Interfaces, EarlyView.
Plasma‐sequence‐engineered ALD (PSE‐ALD), based on sequential NH3 and N2 plasma pulses, enables ultrathin, dense SiNx films. ToF‐MS analysis confirms ligand removal via HCl evolution, while increased film density indicates network densification. The resulting SiNx coating provides robust protection of graphite under H2 plasma exposure.
