LONGi has launched LONGi ONE, an integrated solar-plus-storage product strategy for grid-scale, and commercial and industrial projects, which will be supported by a growing network of 30 new service centres opening in key locations globally by 2028.

Tongwei is partnering with GS-Solar and Golden Solar to develop a large-scale manufacturing facility for hybrid heterojunction back-contact solar cells that combine HJT passivation, tunneling oxide and polysilicon structures used in TOPCon designs, and the grid-free front-side architecture typical of back-contact technologies.

The result was certified by China’s National Photovoltaic Industry Metrology Test Center. The cell utilises a perovskite top device with MBT-ligand-controlled crystallisation on a TOPCon silicon bottom cell, achieving a void-free, high-efficiency tandem structure.

While the world reels from interruption to crude oil supply chains, a new International Energy Agency report shows clean energy technology manufacturing supply chains are at risk, largely due to the world’s reliance on China’s advanced manufacturing and distribution expertise.

JinkoSolar has announced the launch of a new solar module tailored specifically to meet the power density and extreme reliability needs of data centres and AI-driven computing.

China’s 2026 to 2030 policy plan elevates clean electricity as a central driver of economic growth, with greater emphasis on system integration and industrial use.

The Chinese manufacturer said its new rooftop solar module offers 455–475 W power, 22.8–23.8% efficiency, 96-cell double-glass design, and IP68 protection.

Researchers from the Australian National University and Longi used photoluminescence imaging to analyse dopant distributions in RCz-grown silicon wafers doped with antimony, phosphorus, and gallium, finding highly uniform radial concentration profiles suitable for high-efficiency solar cells. The study also found that antimony-doped wafers provide more stable axial doping along the ingot, highlighting their potential for next-generation PV manufacturing.

Sigenergy has launched a 166 kW IP66-rated inverter for C&I solar and storage offering nine MPPT trackers and flexible AC/DC connections. The launch coincided with the opening of its Nantong Smart Energy Centre in China, a 136,000 m² facility for R&D, manufacturing, and global delivery.

The Chinese manufacturer said its new back-contact module delivers up to 545 W and over 25% efficiency in a compact rooftop format for residential, C&I, and off-grid applications.
