Mitigation of UV‐Induced Degradation in Lightweight SHJ Solar Modules via a UV‐Downshifting Encapsulation Strategy

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 6, Page 771-785, June 2026.
Lightweight SHJ solar modules with UV‐downshifting encapsulants effectively mitigated UV‐induced degradation (UVID). However, a reduction in the downshifting (DS) effect was observed, supposedly caused by photooxidation. A novel dual‐layer encapsulation was proposed to ensure the UV utilization and stability of lightweight SHJ solar modules, preserving

Silicon Nanostructures For Efficient Light Absorption In Photovoltaic Devices

Medžiagotyra, 2014
Porous silicon light trapping layers (por-Si LTL) were manufactured using electrochemical etching. Optical measurements have shown the improved por-Si LTL optical properties versus bulk silicon.

Passivating Contacts‐Related Ultraviolet‐Induced Degradation in Silicon Heterojunction Solar Cells

Small Structures, Volume 7, Issue 6, June 2026.
Highly transparent nc‐SiC:H passivating contacts are shown to reshape ultraviolet‐induced degradation in silicon heterojunction solar cells. By shifting UV energy deposition toward the c‐Si near‐interface region, these contacts promote Si& ─;H bond rupture and chemical passivation loss, while hydrogen‐related microstructural rearrangements increase ...

Macroporous Silicon Structures for Light Harvesting

Medžiagotyra, 2015
Macroporous silicon light trapping layers on the surface of p-type substrates were manufactured by using electrochemical etching. Optical measurements have shown the decreased optical reflection as compared to bulk silicon. The p-n junction was formed by

An Archaeometallurgical Investigation on Some Archaeological Metal Finds From the Sasanian Site of Jahāngir, Western Iran

Archaeometry, Volume 68, Issue S1, Page S103-S115, April 2026.
ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and
