Ag‐Induced Phase and Defect Engineering of Co‐Evaporated Sb2Se3 Thin Films for Enhanced Photovoltaic Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The sequential formation of Ag2Se and AgSbSe2 phases at the Sb2Se3/Mo interface upon Ag incorporation in co‐evaporated Sb2Se3 solar cells promotes grain growth and defect passivation. These newly formed intermediate phases enhance crystallinity and suppress recombination, leading to significant improvements in open‐circuit voltage, fill factor, and ...

Microscopic defects as the limiting factor in the direct transmission of nanocoatings obtained through self‐assembly

Nano Select, 2021
Colloidal lithography is a very popular method to achieve large‐scale antireflective coatings. Those sometimes display large a falloff in direct transmission for short wavelengths, which has been linked to scattering.

Electromagnetic momentum in a dielectric and the energy--momentum tensor

, 2012
The Abraham--Minkowski momentum controversy is the outwardly visible symptom of an inconsistency in the use of the energy-momentum tensor in the case of a plane quasimonochromatic field in a simple linear dielectric.

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.

Grid Optimization of Tunnel Oxide Passivated Back Contact Silicon Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
The grid pattern design of tunnel oxide passivated back contact silicon solar cells were optimized via device simulation and the estimated cell efficiency was correlated to the required Ag paste consumption. The absolute efficiency gain of zero‐busbar design over pad‐based contact design is more than 0.1%, with increasing advantage when the Ag paste ...

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
