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

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 10, Page 1277-1291, October 2026.
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.

Foundations of Wilson Lines and Loops From Basic Concepts to Gauge Field Reconstruction

open access: yesFortschritte der Physik, Volume 74, Issue 10, October 2026.
Wilson lines and Wilson loops are reviewed as parallel transport observables in continuum gauge theory. Full holonomy data recover the local connection and curvature through short segment and small loop limits. Traced Wilson loops are gauge invariant but lose matrix information, so reconstruction requires a compatible lift constrained by trace ...

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Scalable Spray Processing Resolves the Dimensionality–Transport Trade‐off in Lead‐Free Indoor Photovoltaics

open access: yesSmall Methods, Volume 10, Issue 20, 26 October 2026.
A solvent‐ and halide‐mediated crystallization strategy overcomes the trade‐off between structural reconstruction and vertical charge transport in spray‐deposited Cs3Sb2I9–xClx absorbers. Controlled phase evolution avoids detrimental crystallographic texture while suppressing self‐trapping and extending carrier lifetimes, enabling efficient vertical ...
