Australian team boosts zinc-iodine battery performance with dry process
Australian researchers have developed a new dry electrode fabrication strategy for aqueous zinc-iodine batteries. They say it delivers cathodes with more than double the performance of iodine and lithium-ion batteries.
German startup offers protic ionic liquids for perovskite solar cell production
Solaveni, a German fine chemical manufacturer, is commercializing protic ionic liquid materials that reportedly enable more stable, water-based halide perovskite inks suitable for use in scalable thin film manufacturing processes.
Dutch startup offers roof coating increasing PV safety
AllShield Coatings says that its fire-resistant product can be installed under a new roof covering or applied to the roofing material of existing roofs. It weighs 2.8 kg/m2 and reportedly serves as an effective fire-resistant layer, significantly reducing the risk of fire spreading.
Stadium in Austria now hosting Europe’s largest PVT system
Austria has installed Europe’s largest photovoltaic-thermal (PVT) solar system at a stadium, using Sunmaxx modules combined with geothermal energy and brine heat pumps to provide climate-neutral electricity and heat.
Agrivoltaics for cherries
Switzerland’s Energie360° and solar tech specialist Insolight have agreed to build a 1,300-panel agrivoltaic plant on a cherry farm in Leuggern, Switzerland. The facility will combine crop protection and dynamic light management.
Different dust, different impact on PV module performance
Scientists in Germany have collected dust from Qatar, Morocco and Thailand to analyze the impact on the performance of uncoated solar glass and uncoated PV mini-modules. Their analysis has shown that dust coverage could range from 4% to 60%.
New study confirms sensitivity of heterojunction solar cells to soldering flux
Researchers in South Korea have found that the contamination by small amounts of soldering flux residues during heterojunction PV module manufacturing can induce significant long-term performance degradation. Careful control of flux application methods and incorporating drying steps are proposed as potential solutions.
Italian startup releases 9.8 kWh sodium battery for residential applications
Italy-based Heiwit has developed a 200 Ah sodium-ion battery with a lifespan of 6,000 cycles. The device reportedly offers thermal stability and rapid charging speed.
Enertech unveils geothermal heat pump for residential use
The US-based heating specialist said its new variable-speed water–to–water system has a coefficient of performance of 3.2 at full load and 3.8 at part load.
Glass-free, colored PV modules for building rooftop retrofits, façades
Researchers from Swiss and Austrian institutions have demonstrated a novel design for a glass-free, structurally robust silicon PV module. With a weight below 6 kg/m2, the targeted application is older buildings with weak roof structure.
