Ag Incorporation Strategies in Chalcogenide Solar Cells: Formation Mechanisms and Pathways Toward High Efficiency

open access: yesEcoEnergy, EarlyView.
Ag incorporation emerges as a unifying strategy for optimizing chalcogenide thin‐film solar cells by tailoring crystallization, defect energetics, and junction quality. This review bridges fundamental mechanisms with practical strategies for next‐generation high‐efficiency photovoltaic technologies.

Anode Materials Requirements for Potassium Ion Batteries: Challenges and Future Possibilities

open access: yesEcoEnergy, EarlyView.
This work identifies a critical scale‐up gap between laboratory battery research and industrial targets, driven by low active‐mass loadings and the omission of full‐cell metrics. We outline concrete strategies to bridge this divide, shifting focus toward high‐loading electrodes (> 3 mg cm−2) to ensure practical commercial viability of potassium ion ...

Facilitating Hydrogen Evolution Reaction Activity in Alkaline Water Electrolysis via Formation of Ni‐Co2P Heterojunction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Ni‐Co2P synthesized via a co‐sputtering method exhibits enhanced hydrogen evolution reaction (HER) activity. The formation of a heterojunction between Ni and Co2P plays a crucial role in this enhancement. At the Ni‐Co2P junction, water dissociation is significantly promoted, while the Ni sites facilitate efficient hydrogen evolution.

Doped Ta3N5 Semi‐Transparent Photoanode Enabling Stable Solar Redox Flow Cell Operation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Synergistic Al:TiO2 underlayer and La doping stabilize semitransparent Ta3N5 photoelectrodes for over 90 h of continuous operation in alkaline solution. The solar redox flow cell demonstrated 12 photocharge–discharge cycles at ∼55% coulombic efficiency using a K4Fe(CN)6|1,5‐DHAQ chemistry. Solar redox flow cells (SRFCs) are photoelectrochemical devices

Se‐Vacancy Engineering Enables Dual Electronic and Interfacial Regulation in SnSe2 Nanocatalysts for High‐Performance Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Se vacancies in SnSe2 induce local electron redistribution and create unsaturated Sn sites, enabling a switch from single‐site to dual‐site adsorption of lithium polysulfides. This structure synergistically enhances redox kinetics, accelerates sulfur conversion, suppresses the shuttle effect, reduces polarization, and significantly improves the ...

Hydroflux Access to Hydroxide‐Free Yttrium Oxovanadate and Arsenite Layers: K6[Y(VO4)3]·2H2O, K6[Y(VO4)3], and Na3[Y(AsO3)2]

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Strongly alkaline hydroflux media commonly yield hydroxide‐rich rare‐earth compounds. In contrast, K6[Y(VO4)3]·2H2O, its anhydrate K6[Y(VO4)3], and Na3[Y(AsO3)2] show that the low activity of water in the medium can favorcondensation into extended hydroxide‐free Y─O─V and Y─O─As networks instead of isolated hydroxo complexes.
