UNSW research offers guidance for more robust TOPCon solar cells
UNSW researchers developed an experimentally validated model linking UV-induced degradation in TOPCon solar cells to hydrogen transport, charge trapping, and permanent structural changes in the passivation stack. They show that thicker aluminum oxide layers significantly improve UV resilience by limiting hydrogen migration, offering clear guidance for more robust TOPCon designs.
Astronergy launches 670 W TOPCon solar module with 24.9% efficiency
China’s Astronergy says its ASTRO N7 Pro module targets utility-scale PV plants and commercial rooftops, offering quarter-cell architecture, bifacial gains, and a 30-year performance guarantee.
Rising silver prices drive China’s Longi shift to copper-metallised solar cells
China’s Longi says it will begin mass production of base-metal PV modules in the second quarter of 2026 as rising silver prices intensify pressure to reduce metallisation costs.
Trina Solar posts new milestones for tandem efficiency, module power
Trina Solar says new certified results in perovskite-crystalline silicon tandem cells and modules demonstrate progress toward industrial-scale next-generation PV.
Aiko achieves 24.8% efficiency in commercial solar module production
The result relates to the company’s Comet 3N modules and has been confirmed by independent testing agency TÜV Nord in Germany.
All solar cell efficiencies at a glance – delayed
The research group led by Professor Martin Green has not published yet Version 67 of the solar cell efficiency tables, due to production delays. Green, however, has agreed to comment on some of the results to be added in the upcoming edition.
Back contact perovskite solar cell efficiency improved with breakthrough research
South Korean researchers have developed a novel bilayer tin oxide electron transport layer for improving efficiency and stability of back-contact solar cells.
The impact of transparent conductive electrodes on perovskite-silicon tandem solar cell performance
An Oxford researcher has found that transparent conducting electrodes can reduce perovskite–silicon tandem solar cell efficiency by over 2%, with losses linked to electrical resistance, optical effects, and geometric trade-offs. Using a unified optical–electrical model, the scientist showed how careful optimisation of TCE stacks, coatings, and cell design is critical to closing the gap toward the 37%–38% efficiency frontier.
Research reveals impact of laser-assisted firing on TOPCon solar cell performance
A group of researchers from the University of New South Wales and Chinese module manufacturer Jolywood has conducted a comprehensive assessment of how laser-assisted firing processes influence the behaviour of TOPCon cells under the thermal conditions encountered during soldering, lamination, and high-temperature stress.
