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.
Saatvik Green commissions 2 GW EPE film manufacturing facility
Saatvik Green Energy has commissioned a 2 GW in-house EPE film manufacturing facility at its Ambala campus in Haryana.
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.
Solar glare forces panel removal at Amsterdam Airport
Glare from a nearby solar park forced temporary runway closures at Amsterdam Airport Schiphol, prompting Dutch authorities to order the removal of about 78,000 PV modules and apply anti-reflective film to others. The solar park operator, however, decided to replace all the panels. The largest portion of the removed, near-new modules have since been acquired by BM Energy and are expected to be redeployed in projects where glare is not a concern.
Emmvee starts production at 2.5 GW solar module line in India
With the new line becoming operational, the company’s total solar module manufacturing capacity has increased to 10.3 GW.
Too much to choose from, too little to decide
Market pressure in the solar and storage sectors often favors low-cost solutions, but long-term success depends on balancing price, quality, and reliability for assets designed to operate for decades. Numerous examples, from low-grade silicon modules to residential hydrogen and redox flow storage, show how technically ambitious products can fail when costs, complexity, or durability are misjudged.
China files WTO complaint against Indian solar subsidies
China’s commerce ministry has raised a complaint at the World Trade Organization (WTO) regarding India’s solar subsidies, claiming they give the country’s domestic industry an unfair advantage and harm Chinese interests.
