Carbon-embedded Pt alloy cluster catalysts, including PtFe, PtCo, and PtNi, are developed to minimize Pt usage in proton exchange membrane fuel cells (PEMFCs). The Pt alloy clusters are stabilized within a carbon matrix, while still allowing gaseous oxygen transfer. Demonstrating high activity with low Pt loading, this catalyst exhibits exceptional...

Long-term outdoor monitoring data are combined with energy yield modeling to quantitatively and qualitatively investigate the effect of light-soaking metastability in both single-junction and tandem perovskite-based PV devices. Using a novel empirical formalism, the energy harvesting losses associated with the light-soaking effect are analyzed for...

This review comprehensively explores recent advancements in thin c-Si solar energy devices, including techniques for producing thin films, advanced light trapping methods, surface passivation strategies, and thin wafer management approaches. It also explores the wide-ranging applications of thin c-Si solar cells and sheds light on the techno-economic...

Tin selenide (SnSe), as an innovative active multifunctional separator, can provide high conductivity to improve the insulation of the sulfur cathode, and the large interlayer spacing allows lithium, sodium, and potassium ions to migrate quickly between the cathode and anode. In short, the SnSe multifunctional separator provides multiple active sites...

A series of 2,2′-thienoviologens (2,2′-SV2+) that demonstrated superior optoelectronic properties compared to both 4,4′-thienoviologens and parent 2,2′-viologens are synthesized. These 2,2′-thienoviologens are combined with g-C3N4 for visible-light catalytic production, the hydrogen release efficiency of the 2,2′-thienoviologens-modified composites...

A facet-dependent mechanism is demonstrated for highly-reversible and long-term stable ion insertion chemistry in TiS2 anode for the first time. The selective exposure of crystal planes is uncovered to effectively suppress the occurrence of hydrogen evolution reaction and transform the charge storage mechanism from the zinc ion insertion/ extraction...
