WTO accuses China of low transparency on state subsidies, including solar
The World Trade Organisation Secretariat has criticised China for an alleged lack of transparency in its state support framework and has urged the nation to improve its subsidy notification process.
Singaporean startup achieves 22.6% efficiency for perovskite solar module
Singfilm Solar said the result has been certified by China’s National PV Industry Measurement and Testing Center.
All solar cell efficiencies at a glance – updated
The research group led by University of New South Wales Scientia Professor Martin Green has published Version 64 of the solar cell efficiency tables. There are 19 new results reported in the new version.
JA Solar debuts 23.3%-efficient single-glass, anti-dust solar panel
The new module has a power output of up to 650 W and weighs 29.6 kg. It uses JA Solar’s patented anti-dust frame technology, which reportedly enhances drainage and decontamination performance, thus reducing dust accumulation and avoiding hotspot issues.
UNSW team creates vortex generators for passive solar module cooling
University of New South Wales researchers have created vortex generators that can reportedly reduce the operating solar module temperature by up to 2.5 C. They built two different prototypes, based on aluminum and a conductive 3D printable polymer, and tested them under several scenarios in an experimental setting deployed in Sydney.
JA Solar takes top spot on WoodMac’s list of PV module manufacturers
Wood Mackenzie says that JA Solar has taken first place on its list of solar panel manufacturers. Nine of the first 12 positions are held by Chinese manufacturers, seven of them could surpass 100 GW of capacity by 2027, and eight are self-sufficient in cell capacity, according to the research firm.
Longi presents 24.4%-efficient 660 W HPBC solar panel
Intended for applications in utility scale PV projects, the new Hi-MO 9 module is available in eight versions with power output ranging from 625 W to 660 W and power conversion efficiency spanning from 23.1% to 24.4%.
Leapton debuts 600-625 W TOPCon solar panel based on rectangular wafers
Leapton Energy says its new panels have a temperature coefficient of -0.30% per C and an efficiency of up to 23.14%. They come with a 30-year power output guarantee for 87.4% of the initial yield.
JinkoSolar claims 33.24% efficiency for perovskite-silicon tandem solar cells
JinkoSolar says it has achieved a 33.24% efficiency rating for its perovskite-silicon tandem solar cells, confirmed by the Shanghai Institute of Microsystem and Information Technology under the Chinese Academy of Sciences.
Study finds excessive row spacing has limited effect on improving PV system performance
Scientists in China have tested the influence of panel row spacing in increasing a PV system performance in a full-scale outdoor PV array experimental platform. They found that larger row spacing plays a limited role in improving thermal convection, observing that solar irradiance and wind speed are the key parameters for optimal PV system design.
