A research group led by Professor Martin Green has published Version 60 of the Solar cell efficiency tables.

The government of the Australian state of Queensland has committed AUD 48 million ($33 million) to develop two pumped hydro projects.

Longi Solar outlines its high-temperature mitigation logic in designing the lower current, high-wattage Hi-MO5 solar panel series.

The US National Renewable Energy Laboratory has demonstrated high-flow-rate hydrogen fueling for heavy-duty vehicles, while France’s TotalEnergies has signed a deal with Adani Enterprises to produce green hydrogen in India.

Lake Onslow, New Zealand, could become home to one of the world’s largest pumped-hydro storage facilities. A local consortium is now conducting a feasibility study and is investigating possible system designs and precise locations.

US-based H2 Industries plans to produce hydrogen from organic waste and non-recyclable plastic. pv magazine recently spoke with its executive president, Michael Stusch, about the main technologies behind the project.

UK scientists have compared the performance of lithium-ion storage systems and vanadium redox flow batteries for a modeled 636 kW commercial PV system in southern California. They have found that both technologies, coupled with an oversized PV array, could achieve a levelized cost of electricity of less than $0.22/kWh, while offering a self-sufficiency ratio of 0.95.

Japanese scientists have developed a piezoelectric-photovoltaic cell with potential applications in indoor environments. They fabricated it on a flexible polyethylene terephthalate film with sputter-deposited ZnMgO thin film and photo-absorbing selenium as the n-type window layer and p-type layer, respectively.

Japan’s Arth has designed an autonomous habitation module that produces water in places without energy and water infrastructure. The company said the residential unit could also be used as an emergency evacuation site.

The EU Parliament has voted to end combustion vehicle sales in 2035, Siemens has announced plans to develop wireless charging for electric vehicles, and Lightyear has launched the final design of its long-range, production-ready solar car.
