Enhanced Photostability and Reduced Burn‐In Losses in Organic Solar Cells via a 2PACz‐Modified PEDOT:PSS Hole Transport Layer

Advanced Materials Interfaces, Volume 13, Issue 17, 8 September 2026.
A PEDOT:PSS/2PACz hole transport layer reduces burn‐in degradation and enhances the photostability of organic solar cells. The interfacial modification with 2PACz mitigates photo‐induced interfacial disorder, enabling stable power conversion efficiencies under continuous illumination for over 650 h.

Mixed‐Polymer Hole Transport Layers Reinforce Au‐Anode Top Emitting Perovskite Light Emitting Diodes

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Au‐anode corrosion is shown to occur rapidly under voltage bias in MAPbI3 perovskite LEDs. Resulting Au+ migration quickly leads to device shorting and unstable emission during constant current driving. We demonstrate that using a simple mixed‐polymer hole transport layer containing polyTPD and PVK can reduce Au‐corrosion and stabilize LED operation ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, Volume 13, Issue 51, 14 September 2026.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Synergistic Interface Engineering via Buffer Layer and UVO Treatment for High‐Performance PbS Quantum Dot Near‐Infrared Photodiodes

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A dual‐interface strategy combining a solvent‐orthogonal Poly‐TPD buffer with UV–ozone tuning of PbS‐EDT reconstructs interfacial energetics and defect chemistry in PbS CQD photodiodes. The optimized interface suppresses shunt‐ and trap‐related leakage, reduces noise, and enables high‐detectivity near‐infrared detection with imaging capability ...

Beyond the Gold Standard: Towards Industrially Viable Electrodes for Durable Perovskite Solar Cells

Advanced Energy Materials, Volume 16, Issue 34, 9 September 2026.
Transparent and opaque electrode materials are mapped by raw material cost per 1 m2 electrode area and retained median device efficiency after heat–light ageing. FTO offers a lower‐cost and more stable alternative to ITO, while Cr/Al provides the lowest‐cost rear electrode investigated with Au‐like stability and substantially improved durability ...
