Eco‐Friendly Laser‐Induced Graphene/Perovskite Hybrids for Eco‐Friendly Photodetectors

open access: yesAdvanced Electronic Materials, EarlyView.
A sustainable paper‐based photodetector was developed by combining laser‐induced graphene (LIG) with MAPbI3 perovskite. Compared with pure LIG devices, the hybrid photodetector exhibited nearly 10‐fold higher responsivity and 7‐fold greater detectivity while maintaining stable performance after 1000 bending cycles, demonstrating its potential for ...

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces

open access: yesAngewandte Chemie, EarlyView.
Hydroxyl‐functionalized dicarbaporphyrinoid polymers synthesized on Au(111) enable tunable oxygen‐mediated connectivity under UHV conditions. Thermal activation yields one‐dimensional hydroxyl‐terminated polymers that can selectively evolve into either covalently‐linked dibenzo‐p‐dioxane architectures through intermolecular C–O–C coupling or two‐fold ...

High‐Responsivity and Fast‐Response Organic Phototransistor Based on Dinaphtho[2,3‐b:2′,3′‐f]Thieno[3,2‐b]Thiophene

open access: yesAdvanced Electronic Materials, EarlyView.
Low‐temperature Al/Al2O3/DNTT/Au organic phototransistors fabricated on flexible PEN combine high responsivity to blue light (≈250 A W−1 at 39 nW cm−2) with detectable modulated photoresponse up to 150 kHz, making them promising for ultra‐low‐light sensing and moderate‐speed optical links.

Alcohol‐Adduct Mediated Precursor Stabilization Strategies for Conformal SnO2 Layers in Highly Efficient and Stable Perovskite Solar Modules

open access: yesAdvanced Energy Materials, EarlyView.
An alcohol‐adduct‐mediated strategy is employed to stabilize tin isopropoxide for the formation of a homogeneous double electron transport layer (ETL) incorporating SnO2 nanoparticles (NPs). This double‐ETL exhibits improved optical and charge‐transport properties due to reduced defect density and better energy level alignment, resulting in high ...

Emerging Materials and Future Strategies for Solid Oxide Electrochemical Cells

open access: yesAdvanced Energy Materials, EarlyView.
Solid oxide electrochemical cells operate under strongly coupled electrochemical and thermodynamic conditions, where performance is constrained by interactions among crystal structure, defect chemistry, and interfacial evolution. This review, based on a structure‐defect‐property‐durability framework, reveals the roles of lattice symmetry and defect ...
