Neoen begins construction of Tesla Megablock battery in Australia
Neoen Australia has launched construction of its third big battery in less than 90 days, helping accelerate Australia’s energy transition with 20 GW of utility-scale solar, wind, gas, batteries and pumped hydro now either commissioning or under construction.
Singapore team develops durable perovskite-silicon tandem solar cells
National University of Singapore scientists claim that vapor-deposited perovskite-silicon tandem solar cells built on industrial silicon wafers achieve both high efficiency and long-term thermal stability, addressing a central barrier to commercial deployment.
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.
Off-grid floating PV-desalination system for hydrogen production
Scientists have simulated a solar-powered hydrogen production system comprising 32,050 photovoltaic panels, a pumping system, a seawater reverse-osmosis desalination unit, an electrolyzer, and a hydrogen storage tank. Operation of the system in Oman could potentially yield a levelized cost of electricity of $0.05/kWh and a levelized cost of hydrogen of $9.5/kg.
BNEF flags potential global solar slowdown in 2026 as China cools
BloombergNEF (BNEF) projects a slight year-on-year dip in global solar additions in 2026 as China’s growth eases, even as installations elsewhere continue to rise.
The Hydrogen Stream: CMB.Tech secures China green ammonia offtake
CMB.Tech has secured an offtake agreement for renewable ammonia from CEEC Hydrogen Energy’s 800 MW wind-and-solar-powered project in China, while Germany’s Gascade Gastransport said it has converted about 400 km of gas pipelines to form a new hydrogen transport corridor.
BYD surpasses 1.5 million residential storage systems worldwide
BYD says global installations of its BatteryBox residential energy storage systems have increased by 500,000 since June 2024, lifting the total past 1.5 million worldwide.
EU countries to pilot subscription model for heat pumps
An EU-funded project is introducing a heat pump on subscription model designed to increase the uptake of heat pumps in rented accommodation, with pilot actions planned in Austria, France and Greece.
