Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency
Progress in Photovoltaics: Research and Applications, EarlyView.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.

Depth-prediction method for direct laser-scribing processes
Applied Surface Science, 2017 Many semiconductor technologies require the patterning of films to create features not easily achieved during growth or deposition. In the case of transparent conductive oxides (TCOs), this is typically realized through direct laser-scribing. Although there are models conceived to predict the depth of a scribe, the necessary parameters to obtain a ...

Glass breaking strength: The role of surface flaws and treatments [PDF]
Although the intrinsic strength of silicon dioxide glass is of the order of 10 to the 6th power lb/sq in, the practical strength is roughly two orders of magnitude below this theoretical limit, and depends almost entirely on the surface condition of the ...

First Flexible All‐Perovskite Tandem Minimodule Using Au‐Free Recombination Junction
Advanced Photonics Research, Volume 7, Issue 4, April 2026.Through the development of a thin‐indium tin oxide recombination layer with a high lateral resistance combined with a compact SnO2 buffer layer, stacking MA‐free wide bandgap and narrow bandgap subcells is successfully achieved. Also, thanks to the implementation of a suitable laser scribing process, 11 cm2 all‐perovskite tandem minimodules are ...
