DFT Modeling and Impedance Spectroscopy Analysis of a High Performance Zirconia‐Based Solar Cell

Nano Select, EarlyView.
p‐SnS/n‐CdS heterojunction solar cells with Al‐ZnO/i‐ZnO window layers simulated using SCAPS‐1D and impedance spectroscopy enabled tracking of solar cell parameters. The optimal performance (η = 22.76%, Voc = 0.77 V) was achieved with a 5 µm SnS absorber at Rs = 1Ω.cm−2 and Rsh = 10 kΩ.cm−2.

Lanthanide‐Doped NaGdF4 Nanoparticles as Versatile Luminescent Labels for Cathodoluminescence Mapping

physica status solidi (b), EarlyView.
This study presents a synthesis method for lanthanide‐doped NaGdF4 particles in an aqueous environment. Clearly distinct cathodoluminescence (CL) spectra were observed for europium‐ and thulium‐doped nanoparticles, stable for up to 100 s of excitation time.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Substitutional Sulfur and Its Vibrational Fingerprints in Sb2Se3

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The microscopic configurations of sulfur incorporated into the Sb2$_2$Se3$_3$ lattice are studied by combining infrared absorption spectroscopy with density functional theory. Substitutional SSe$_{\mathrm{Se}}$ defects are identified as the origin of four distinct sulfur‐related local vibrational modes at 249, 273, 283, and 312 cm−1$^{-1}$.

Recent Advances in Chemical Bath Deposition of Electron and Hole Transport Layers for Perovskite Solar Cells and Modules

Rare Metals, EarlyView.
ABSTRACT The development of high‐efficiency, stable, and scalable perovskite solar cells/perovskite solar modules (PSCs/PSMs) highly depends on the performance and cost‐effectiveness of functional layers such as electron transport layers (ETLs) and hole transport layers (HTLs).

Climate‐Resilient Crop Production Under Agrivoltaics: Experimental Evaluation of Amaranth Production With Semi‐Transparent Photovoltaic Modules in Canada Under Changing Climates

Sustainable Development, EarlyView.
ABSTRACT Climate change threatens global food security, requiring climate‐smart systems that enhance both crop resilience and sustainable energy production. While agrivoltaics is recognized for combining solar power generation with agriculture, its effects on emerging stress‐tolerant crops such as amaranth remain largely unexplored, particularly under ...

Efficient, Reversible Lead Adsorption in a Thiol‐Decorated Zirconium‐Metal–Organic Framework

Small, EarlyView.
A thiol‐decorated Zr‐MOF, Zr‐DMSA, efficiently captures Pb(II) from water via mixed S/O chelation enabled by flexible “dangling” ligands, as revealed by solid‐state NMR and pair distribution function analyses. Treatment with 1 M HCl fully reverses Pb binding, regenerating the material for up to 10 consecutive adsorption–desorption cycles.

Assessing Proton Radiation Hardness of Antimony Chalcogenide Solar Cells

Solar RRL, EarlyView.
This paper discusses the effect of proton radiation on the device performance of antimony chalcogenide solar cells. Sb2S3 and Sb2(S, Se)3 solar cells are exposed to two different proton energies (100 and 300 keV) with fluences ranging from 1011 to 1014 protons/cm2.
