Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 942-956, July 2026.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

Chemical Pre-treatment Methods for Measurement of Ge Isotopic Ratio on Sphalerite in Lead-Zinc Deposits

Yankuang ceshi, 2014
Up to the present, main research of Ge isotopes has been carried out on organic, magmatic and meteoritic samples. Pb-Zn deposits are one of the most important reservoirs of Ge; however, there are few studies on Ge isotopes for these samples.

Flotation of Sulphide Minerals Using Organosolv Lignin as Collector—Pilot-Scale Trials

Materials Proceedings
The use of toxic chemicals as flotation reagents raises concerns about the sustainability of the process and its environmental impact. Xanthates are a family of efficient collectors that find application in the selective recovery of lead, gold and zinc ...

Physicochemical constraints and fluid evolution pathways in skarn mineralization: insights from sphalerite geochemistry at the Dafang Pb–Zn–Au–Ag deposit, South China

Frontiers in Earth Science
Important Mid-Late Jurassic Pb–Zn polymetallic skarn deposits are widely distributed in South China, yet physiochemical conditions and migration of the ore-forming fluids in skarn deposits are poorly constrained. The Dafang Pb–Zn–Au–Ag deposit (38 kt Pb @
