New research from Hong Kong confirms that rooftop PV systems could 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.

JinkoSolar led global PV module shipments in 2024, followed by JA Solar, Longi, Canadian Solar and Trina Solar, according to Wood Mackenzie. The research firm notes a growing shift toward full vertical integration among top manufacturers.

An international research team has observed a significant increase in series resistance in LECO-treated TOPCon solar cells after temperature and bias treatment. The scientists said they now need to conduct further investigations into its impact on cell efficiency, reliability, and bankability.

The research group led by Professor Martin Green has published Version 66 of the solar cell efficiency tables. There are 21 new results reported in the new version.

Researchers in China have fabricated a perovskite-TOPCon solar cell with a top perovskite device utilising a self-assembled monolayer aimed to improved cell stability. The tandem cell achieved a high fill factor and a certified efficiency of 30.9%.

Australian researchers have identified five contaminants that could increase damp heat-induced degradation in TOPCon and heterojunction cells and modules. Their analysis has shown these contaminants could originate from improper handling during cell or module processing.

Researchers from the University of New South Wales have teamed with international colleagues to develop a metallisation technique for TOPCon solar cells that can reportedly reduce silver usage in the devices’ rear side by 85%.

Longi has developed the Hi-MO S10, a residential heterojunction (HJT) back-contact solar module with 25% efficiency, combining 27.6%-efficient cells with up to 510 W output and 252.3 W/m² power density.

The battery unit of the Chinese PV manufacturer said its new large-scale battery has a lifecycle of more than 12,000 cycles. The system has a nominal capacity of 5 MWh and a roundtrip efficiency of up to 95%.

New research from the University of New South Wales have found that the Special Injected Metallisation (JSIM) technique developed by Chinese manufacturer Jolywood can considerably increase TOPCon solar cell efficiency. The scientists described precisely how laser-assisted firing enhances cell performance, reportedly filling critical gaps in industrial TOPCon cell optimisation.
