China commissions world’s largest 1 GW open-sea offshore solar project
China has brought a 1 GW offshore solar power plant online off the coast of Dongying, Shandong province, combining PV with energy storage and aquaculture in what is now the world’s largest open-sea solar project in commercial operation.
How to improve indirect-expansion PVT-assisted heat pump performance
Scientists in Thailand have simulated an indirect-expansion photovoltaic-thermal-assisted heat pump and measured its performance under various cold water temperatures and tank sizes.
Leecell develops organic PV for indoor, outdoor use
The South Korean startup is developing organic solar cell technology made using a proprietary roll-to-roll process. It targets both indoor and outdoor integrated PV applications.
Trina Solar posts new milestones for tandem efficiency, module power
Trina Solar says new certified results in perovskite-crystalline silicon tandem cells and modules demonstrate progress toward industrial-scale next-generation PV.
PV redox flow battery with 4.2% solar-to-electricity conversion efficiency
Scientists in China have constructed and tested a device that uses redox couples paired with a single triple-junction amorphous-silicon photoelectrode. When tested under a xenon lamp simulating one sun, the device achieved an average solar-to-electricity conversion efficiency of 4.2%.
Korean researchers build tin monosulfide solar cell with 4.81% efficiency
The efficieny result represents one of the best performances ever achieved for this kind of thin-film solar cell to date. The device was fabricated with a rear contact interface that reportedly enhances charge transport.
Carmaker uses repurposed EV batteries to help power production plant
Repurposed electric vehicle batteries have been used for the energy storage component of a solar and battery project that is now helping power operations at carmaker Nissan Australia’s aluminium casting plant in Victoria.
Remote sensing-based tech for hourly snow-induced PV power losses assessment
A team of Sweden-based researchers has developed a snow loss model to estimate snow-induced PV power losses on an hourly basis. The proposed approach relies solely on data from remote sensing sources, such as aerial imagery, LIDAR, and satellite data.
Aiko achieves 34.76% efficiency for 2-terminal perovskite-silicon tandem solar cell
The Chinese manufacturer said its 2-terminal 34.76%-efficient perovskite-silicon tandem lab-scale cell is based on heterojunction technology and developed by a collaboration of Solarlab Aiko Europe, Aiko headquarters, and its R&D in Yuwi, China.
Research shows vacuum melting is key to efficient silicon kerf recycling
Researchers in Norway investigated the melting behavior of silicon kerf agglomerates under different atmospheres and temperatures to improve recycling for solar-grade silicon. They found that vacuum melting enhances deoxidation and produces a homogeneous, oxide-free melt, while agglomerate size has little effect on melting behavior.
