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

Progress 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.

Universal Confinement Length Governs Radical Depolymerization Kinetics in Nanoconfined Polymers

Small, Volume 22, Issue 59, 22 October 2026.
Analysis of PMMA depolymerization kinetics identifies a critical threshold under extreme nanoconfinement where segmental mobility saturation prevents further increases in depolymerization temperature. ABSTRACT Thermal depolymerization is typically studied in bulk, yet many systems involve polymers confined within nanoscale geometries. Understanding how

Engineering Cobalt‐Based Thin Films for Fischer–Tropsch Synthesis

Small, Volume 22, Issue 60, 27 October 2026.
Cobalt thin films with tailored crystalline phases and oxidation states serve as well‐defined model Fischer–Tropsch catalysts. In situ synchrotron GIXRD reveals distinct reduction behaviour and phase evolution, while catalytic testing demonstrates phase‐dependent hydrocarbon selectivity and improved structural stability. These model thin‐film catalysts

Enhancing Chiroptical Selectivity and Device Stability of Chiral Perovskite Photodetectors Via Interfacial AlF3 Passivation

Small Methods, Volume 10, Issue 19, 7 October 2026.
An ALD‐grown AlF3 underlayer promotes grain growth, defect passivation, and improved crystalline ordering in chiral perovskite films. The resulting films exhibit enhanced chiroptical properties, superior circularly polarized light photodetector performance, and improved stability, establishing an inorganic interface‐engineering strategy broadly ...

Rapid Atmospheric Vapor Deposition of H:In2O3 Transparent Conducting Oxide Thin Films

Small Structures, Volume 7, Issue 10, October 2026.
Atmospheric‐pressure chemical vapor deposition enables rapid growth of high‐mobility H:In2O3 transparent conducting oxide at only 140 °C without need for ozone or plasma. A high growth rate of 0.19 ± 0.01 nm s−1 is achieved, while the high mobility from hydrogen doping enables a low‐sheet resistance as low as 7.2 Ω sq−1, along with high NIR ...
