Nextracker inks 1 GW supply deal and claims up to 12% bifacial yield gain
The 1 GW fifth phase of the Mohammed bin Rashid Al Maktoum Solar Park in Dubai will feature NX Horizon trackers with the deal announced after the manufacturer published new bifacial yield gain claims.
New molecular precursor for kesterite solar cells
Scientists in India have developed a new molecular precursor for applications in kesterite solar cells. They used the precursor to build a superstrate type solar cell with an efficiency that is purportedly among the highest ever recorded. They relied on a low-temperature process to manufacture the device.
Solar-powered unmanned airplane with lithium-sulfur battery
The Korea Aerospace Research Institute has conducted a battery-powered test flight of solar-powered unmanned aerial vehicle EAV-3. The aircraft is powered by solar cells on its wings and body and an LG Chem lithium-sulfur battery.
Solaria brings its patent claims against Canadian Solar to ITC, adding a third patent
Californian solar module manufacturer Solaria Corporation has asked the U.S. International Trade Commission to issue an exclusion order to prevent the sale in the United States of Canadian Solar shingled solar modules it claims infringe its patents.
Thin-film agrivoltaic solar tubes
German tech company Tube Solar AG has secured €10.8 million to develop its cylindrical agrivoltaic modules. The lightweight devices could also be used on roofs until now considered unsuitable for PV.
New world record for large-area organic PV module efficiency
Scientists in Germany have achieved 12.6% efficiency with a 26 sq cm organic panel and 11.7% for a 204 sq cm device. The feats were achieved with a new module layout and a slower, high-resolution, short-pulse laser structuring process.
Plasma enables smaller, more powerful NMC-811 cathodes
Batteries could shrink even more with smaller crystals in the cathodes. Battery packs in electric vehicles and consumer goods could become smaller, while still offering high performance.
From tandem cell to double absorber for 34.45% efficiency
Scientists in the United States theorize that a ‘double absorber’ cell comprising two active thin-film layers within one cell stack could achieve impressive efficiencies, whilst eliminating many of the challenges inherent to the design of tandem cells. For now though, it’s only on paper.
Tandem cells head outdoors
Scientists in Saudi Arabia headed outdoors to test the effects of the region’s high desert temperatures on the performance of small perovskite-silicon tandem cells in several different configurations. Their findings could offer new insight into selecting the best materials for long-term stability in the field.
Vanadium redox flow battery for storage of wind and solar power
Researchers in India have developed a 5 kW/25 kWh vanadium redox flow battery with an energy density of 30 watt-hours to 40 watt-hours per liter.
