World Solar Challenge back on track in Australian outback
A new generation of solar-powered cars is set to be tested in the harsh Australian outback next year after organisers of the World Solar Challenge confirmed the international car racing event will make its return in 2023.
Fully autonomous robot for solar O&M
OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.
Thermally integrated PV-electrolyser with 9.1% solar-to-hydrogen efficiency
A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyser based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyser achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.
Weekend read: Sodium-ion batteries go mainstream
Sodium-ion batteries are emerging as a viable alternative to lithium-ion technology. Industrial heavyweights CATL and Reliance Industries, following the acquisition of UK-based sodium-ion specialist Faradion, are bent on bringing the technology out of the lab and into mass production. Against a backdrop of soaring prices and predicted shortfalls of lithium-ion battery materials, sodium-ion chemistry has never been more tantalising.
Q Cells, German researchers claim 28.7% efficiency for 2T perovskite-silicon tandem solar cell
The Korean manufacturer and the German research centre were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.
