South Korean researchers from Chungnam National University have developed a one-step, photoresist-free graphene patterning technique that results in very low electrical resistance and avoids damage, showing scalability in the fabrication of transparent, flexible electronics like solar cells.

For the last decade, the global conversation around electric vehicles (EVs) has focused almost entirely on adoption. Targets, incentives, charging stations and sales figures have dominated headlines. The EV transition is happening daily, at street level, across the Asia-Pacific region and beyond. Yet a far less glamorous question is now becoming just as important as how many EVs we sell: what happens when their batteries are no longer good enough for the road?

The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of more than 9,500 cycles at a high 95% depth of discharge.

Recycling solutions company Livium has for the first time shipped 600 end-of-life solar panels to South Korea, where a strategic partner, Won Kwang S&T will validate their proprietary technology for large-scale solar panel recycling.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial applications, and a liquid-cooled energy storage system.

China-based PV equipment supplier Ideal Energy Sunflower Semiconductor has completed an AI-enabled pilot line for ultra-thin, flexible heterojunction solar cells, targeting lightweight power systems for space and near-space applications.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85 C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.

Researchers in China developed a novel two dimensional seeding agent to regulate crystallisation in a 1.80-eV wide-bandgap perovskite film. A perovskite-silicon tandem device made with the resulting optimised subcell achieved an efficiency of 31.13%, outperforming a control device.

Researchers from Australia’s national science agency have teamed with Malaysian authorities to explore how different battery chemistries perform under tropical stressors like heat, humidity and corrosion, and what this means for durability, safety and cost-effectiveness.

The Chinese manufacturer has unveiled its new TOPCon bifacial TNC3.0 module. The 1,500 V, IP68-rated panel offers over 85% bifaciality, a 0.26%/C temperature coefficient, and a 30-year warranty guaranteeing 88.85% output.
