Rooftop PV performance during heatwaves
Chinese researchers have assessed the impact of residential rooftop PV arrays on energy use and surrounding air temperatures during extreme heatwaves. They found that panels with higher conversion efficiencies achieved the best results.
Albania kicks off tender for 12.9 MW floating solar project
Solar Energy of Albania (SENA) aims to develop a 12.9 MW floating solar project on a lake in northwestern Albania, next to an existing hydropower plant.
Flashing solutions for perovskite tandem cells, modules
A new white paper by testing equipment specialist Wavelabs outlines key challenges that the solar industry will face when it comes to testing and characterizing perovskite-silicon tandem cells in manufacturing environments.
Transition metal oxides-based passivating contacts for 21.9%-efficient, n-type solar cell
An Australian research group has shown how passivating contacts based on transition metal oxides could replace contacts based on doped hydrogenated amorphous silicon or polycrystalline silicon in n-type solar cells in the future. They designed a cell with an open-circuit voltage of 665 mV, a short-circuit current of 40.78 mA cm−2, and a fill factor of 80.8%.
Hydrogen storage in vertical caverns
Australia’s Energy Estate has signed a new agreement with Abergeldie, which designs vertical man-made caverns for hydrogen storage. The partnership will focus on a range of projects, including a 1.6 GW hydrogen network.
Stäubli launches dual-rated, 1,500 V branch connector for solar
Stäubli, a Swiss electrical connector manufacturer, has unveiled a new branch connector with both UL and IEC certification.
SunPower doubles earnings in record Q3
SunPower says more American people are turning to solar, as US retail energy prices rose 14.3% year over year through August.
The Hydrogen Stream: Hydrogen production from industrial byproducts
US scientists have reported efficient plasmonic photocatalysis for the production of hydrogen from hydrogen sulfide, with no external heat source. Egypt, meanwhile, has started commissioning Africa’s first integrated green hydrogen plant.
Quantitative methodologies to assess technical risks in PV
Researchers led by Germany’s TÜV Rheinland have created a database of technical risks and mitigation measures for PV installations. Their broad overview of quantification methods has shown that further standardization is required.
Solar dominates renewable corporate PPAs in Asia Pacific, says WoodMac
Corporations in the Asia-Pacific region are set to contract a record 7 GW of renewable capacity in 2022, according to a new report by Wood Mackenzie. Solar accounts for 57% of the region’s contracted corporate renewable power purchase agreements (PPAs) to date. India, Australia and Taiwan account for 89% of overall capacity in the region.
