Perovskite solar cell built through Argon plasma treatment achieves 23.55% efficiency
Researchers in China have used an argon plasma polishing pre-treatment (APP) to remove surface defects and increase passivation effectiveness in perovskite solar cells. The result is a perovskite device with a 2D interface that significantly improves stability and performance.
Collaboration key to scaling new technology
Both the solar module and battery manufacturing industries have been dealing with excess production capacity in recent years, and each is undergoing its own set of market adjustments in 2025. This has meant challenging conditions for manufacturing equipment suppliers in either sector. But there is still plenty of opportunity to deploy the latest technologies at scale, and to assist suppliers moving into new regions. The long-term outlook for both sectors is strong, as pv magazine heard from Wang Yanqing, Chairman of solar and battery production equipment supplier Lead Intelligent, headquartered in Wuxi, China.
Lightsource BP secures financing for 115 MWp fishery solar project in Taiwan

Sungrow unveils PowerTitan 3.0 BESS with 684 Ah cell, silicon carbide PCS
Sungrow has launched the PowerTitan 3.0 battery energy storage system (BESS), built around a 684 Ah cell and a fully liquid-cooled silicon carbide power conversion system.
Rooftop PV may ‘unintentionally’ exacerbate urban heat
New research from Hong Kong confirms that rooftop PV systems significantly contribute raise daytime temperatures in urban environments. The scientists explained that, although their findings highlight important urban resilience considerations, they should not detract from the broader benefits of PV systems for energy sustainability and carbon reduction.
Tata Power hits 4 GW of solar module production capacity
