Biden halts solar tariffs for two years. What’s next?
Paul Wormser and Christian Roselund of Clean Energy Associates joined pv magazine to discuss the moratorium on solar tariffs and other executive actions taken by the White House.
Tandem tin-lead perovskite solar cell with 25.5% efficiency
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.
Vehicle integrated solar to power refrigerated trailers
German VIPV specialist Sono Motors has signed an agreement with French refrigerated vehicle supplier Chereau to develop refrigerated vehicles powered by an integrated solar array. The two companies will build and test a prototype vehicle, and begin to evaluate mass production. Sono estimates that the concept could save around 3,400 liters of fuel and avoid 9 tonnes of CO2 emissions per vehicle, per year.
Premier Energies, Azure Power partner on solar cells, modules
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.
Solar cell efficiencies at a glance – updated
A research group led by Professor Martin Green has published Version 60 of the Solar cell efficiency tables.
High-wattage solar modules increase risk of thermal runaway
Longi Solar outlines its high-temperature mitigation logic in designing the lower current, high-wattage Hi-MO5 solar panel series.
Thin-film flexible piezoelectric-photovoltaic cell based on selenium
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.
Solar-powered offgrid residential unit from Japan
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.
REC Silicon, Ferroglobe to establish traceable US solar supply chain
Investments by Hanwha Group and the potential passage of the Solar Energy Manufacturing Act could expand US production of polysilicon and metallurgical-grade silicon.
Perovksite solar cell with 23.13% efficiency via new passivation approach
Australian researchers built a perovskite solar cell with guanidinium bromide and octylammonium bromide cations. They claim the device can achieve a higher open-circuit voltage, while exhibiting better efficiency and stability.
