Evaluation Of the Functionality of Germanium Arsenide Solar Cells at Multiple Sites Following Distinction In Irradiation [PDF]

E3S Web of Conferences
The efficiency of a GaAs solar cell was 24.3 percent, which at the time was the best of any single-junction solar cell. This paper shows the variation of output power when subjected to a variety of irradiation at different locations in India When ...

Identifying Suitable Front Contacts for High‐Efficiency Cd(Se,Te) Solar Cells on Space‐Qualified Cover Glass

Progress in Photovoltaics: Research and Applications, EarlyView.
Front contact selection governs interfacial stability in CdTe‐based (Cd(Se,Te)) solar cells on ultra‐thin space‐qualified cover glass. Optimized TCO/emitter combinations suppress interdiffusion and deliver up to 16.2% AM0 efficiency with high specific power, demonstrating strong potential for lightweight space photovoltaics.

Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

Cis‐urocanic acid formation following far‐UVC exposure and associated signaling responses in keratinocytes

Photochemistry and Photobiology, EarlyView.
Far‐UVC (200–235 nm) has emerged as a safe and effective indoor disinfection tool, but effects on skin immunomodulation remain unclear. This study demonstrates that 222 nm far‐UVC converts trans‐urocanic acid (UCA) to its biologically active cis isomer at levels comparable with solar radiation. In keratinocytes, far‐UVC alone caused modest increases in

Recent Development in Solar‐to‐Hydrogen Conversion Systems

WIREs Energy and Environment, Volume 15, Issue 3, September 2026.
This review compares three solar‐driven hydrogen production methods, photocatalysis (PC), photoelectrochemical cells (PEC), and photovoltaic–electrochemical (PV–EC) systems by examining their mechanisms, materials, stability, and efficiency. Nanocrystal‐based PC catalysts achieved the highest quantum efficiency (94%), while PV–EC and Si nanowire PEC ...

Chip‐Integrated Metasurface‐GaAsSb Nanowire Array Photodetectors for Single‐Pixel Polarimetric Imaging

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
A 2×2 multiplexed GaAsSb nanowire photodetector array integrated with L‐shaped metasurfaces is developed for miniaturized infrared polarimetry. Leveraging non‐radiating anapole states that facilitate near‐field enhancement, the device demonstrates strong polarization selectivity at 835 nm.
