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.

The Chinese manufacturer has launched a fire-resistant version of its Hi-MO X10 module for distributed PV applications, featuring back-contact technology and up to 24.8% efficiency. The company says the module adds enhanced fire-safety design to address rooftop PV risks such as hot spots and DC arcing.

In an interview with pv magazine, Empa scientist Mirjana Dimitrievska explains that the CIGS photovoltaic technology, while promising for efficiency and flexible applications, faces persistent challenges in scaling lab-level performance to cost-effective, high-throughput industrial production, limiting its ability to compete with crystalline silicon. She also emphasizes that long-term stability, reliability, and material sustainability, rather than peak efficiency, are crucial for commercial viability, especially in niche markets like building-integrated and lightweight PV.

Plans to build Australia’s first large-scale silicon ingot and wafer manufacturing facility in Queensland have been put on the fast track by the federal government in a nod to the project’s potential to play a key role in supporting a domestic solar supply chain.

The new product has a maximum wattage of 725 W, a maximum current of 22 A, and a maximum efficiency of 99.6%.

The Dinawan Solar Farm is one of 14 renewable energy projects valued at $34 billion, that has been included in the opening round of the New South Wales government Investment Delivery Authority EOI endorsement.

The Chinese manufacturer has launched its third-generation Vertex S+ G3 dual-glass TOPCon modules for residential and commercial applications. The new products feature upgraded module architecture and a temperature coefficient if -0.26% per C.
