The US National Renewable Energy Laboratory has made a tandem perovskite solar cell that can retain 80% of its original efficiency after 1,500 hours of continuous operation, or more than 62 days. To improve its stability, they used a hole-transporting material made of phenethylammonium iodide and guanidinium thiocyanate.

Azure Power has agreed to invest in a 1.25 GW mono PERC cell and module production facility that Premier Energies plans to open in India.

Enovix has shown that its US-made silicon anode lithium-ion batteries can charge from 0% to 80% in just five minutes.

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.
