Plastic luminescence in mechanoluminescent composites

InfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.

A novel n‐type dimer dopant for semiconducting polymers

Polymer International, EarlyView.
A novel molecular n‐type dopant (1) with superior capacity to dope conjugated polymers is introduced. After charge transfer the product (2) remains in the polymer. Abstract Efficient and stable doping of organic semiconductors is crucial for adjusting their electrical properties.

Printable and Stable Microlens‐Type Perovskite Quantum Dot Color‐Converting Resin Through Rheology Control for Efficient and Reliable Micropatterning for Full‐Color Displays

Small, EarlyView.
A thixotropic perovskite quantum dot color‐converting resin (thixo‐PQD resin) is developed by rheological control and robust matrix encapsulation, enabling uniform micro‐dispensing of microlens (ML) thixo‐PQD array. The resulting ML thixo‐PQD array shows improved color‐conversion relative to flat PQD films and achieves long‐term environmental stability.

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Advancing Circular Strategies in Photovoltaics: Assessing Reuse Readiness Across Technical, Economic, and Environmental Dimensions in a Case Study

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1077-1099, September 2026.
This study examines the reuse readiness of photovoltaic modules through the Swiss PV Circle project. Results confirm technical feasibility with cost savings from targeted preselection, whereas economic viability depends on module age, testing, and market conditions.

Enabling EVA for TOPCon: How Glass Frit Composition Governs Resistance to Acetic Acid–Induced Corrosion

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1125-1134, September 2026.
This work reveals that glass frit chemistry governs acetic‐acid‐induced corrosion and damp‐heat stability in LAF‐processed TOPCon modules. Compared with a Pb/B‐rich frit, a Ba/Zn‐modified frit preserves the Ag–Si interface, suppresses contact‐resistance increase and improves module reliability.

Shingle Interconnection Reliability of PERC and Thin HJT Cells for Low Earth Orbit Applications

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 9, Page 1159-1172, September 2026.
Evolution of maximum power output (P max) of PERC and thin HJT shingled cells with the Electrically Conductive Adhesives (ECA) “S” and “A” exposed to +120°C/ −120°C thermal cycles up to 5×103 times. Losses are induced by an increased series resistance with all cell technologies and ECA.

Quantifying Perovskite Solar Cell Degradation via Machine Learning From Spatially Resolved Multimodal Luminescence Time Series

Solar RRL, Volume 10, Issue 15, 17 August 2026.
LumPerNet combines automated aging, multimodal luminescence imaging, and leakage‐aware deep learning to predict perovskite solar cell efficiency retention. By combining PLoc, PLsc, EL images, and device‐specific reference states, the framework captures degradation‐relevant optical signatures and shows that global luminescence evolution, complemented by
