Chinese researchers, led by a research team from PV Technology Centre of Tongwei Co., Ltd, used a sequential annealing process in the fabrication of tandem solar cells, featuring a wide bandgap perovskite top cell on a fully-textured commercial crystalline silicon heterojunction bottom cell. The resulting device had a certified power conversion efficiency of 31.4%, outperforming a 29.43%-efficient control cell.

The Chinese manufacturer said its new IEC 61215-certified rooftop PV module relies on a 30 mm aluminum frame and dual-glass construction that reportedly help it withstand extreme snow loads and wind pressure.

The Chinese manufacturer has upgraded its Infinite ABC solar module series with four new product versions. It claims the new modules are the world’s first 500 W panels measuring less than 2 m2.

Researchers in China have created a dataset of various PV faults and normalised it to accommodate different array sizes and typologies. After testing the new approach in combination with the 1D-CNN machine learning technique under different conditions, they found an accuracy of more than 99%.

UNSW researchers are set to scale up a next-generation electrolyser system that helps produce sustainable aviation fuel using renewable energy, thanks to a $1.2 million government grant and $3 million in industry support.

Sungrow Power has revealed its newest hybrid next-gen residential energy storage system, with upgrades to its MG Series inverters and a battery solution to be launched in Q42025.

The Chinese company stated that its new H02 product line is available in either single-phase or three-phase configurations. It comes with a different number of 5.12 kWh batteries.

GoodWe has released its BAT series battery cabinet for small to mid-scale commercial projects, with two capacities at launch at 102.4 kWh and 112.6 kWh, and outdoor use in mind.

Topping the agenda for Prime Minister Anthony Albanese’s visit to China this week has been the massive bilateral opportunity for Australia – the world’s No.1 producer of iron ore, with a 56% share of global exports – to partner with China on developing green iron and steel produced using zero-emissions energy. Traditional practices use coking coal, a carbon intensive, high-emissions fossil fuel, to produce iron from ore, a key step in steelmaking.

To evaluate the outdoor performance and stability of perovskite solar cells using contactless and noninvasive methods, an Australian and Chinese research team found a way to use photoluminescence imaging as well as demonstrating a proof of concept for implied open-circuit voltage imaging. Their research relied on cost-effective equipment that operates under direct sunlight.
