JinkoSolar achieves 34.76% efficiency for perovskite-silicon tandem solar cell
JinkoSolar says it has increased the efficiency rating for its perovskite-silicon tandem solar cells from 34.22% to 34.76%, confirmed by China’s National PV Metric & Testing Center (NPVM).
Sodium-ion battery cell cost could drop to $40/kWh, says IRENA
A report from the International Renewable Energy Agency (IRENA) notes that while it is still uncertain whether sodium-ion batteries will become a disruptive alternative to lithium-ion technology, they could offer significant cost-saving opportunities in applications such as electric vehicles and large-scale energy storage.
Huasun unveils 770 W, 2,000 V heterojunction solar module
The Chinese manufacturer said the higher-voltage design of the new module reduces cable, combiner, pile-foundation, and land-use requirements, delivering balance-of-system savings of up to CNY 0.15 ($0.012)/W in western China. The module offers a power output of 730 W to 770 W and a conversion efficiency of up to 24.8%.
The Hydrogen Stream: EWE begins work on 320 MW hydrogen plant in Germany
EWE says construction has started on its 320 MW hydrogen plant in Germany as it seeks regulatory reforms, while Japan Suiso Energy and Kawasaki Heavy Industries have broken ground on a commercial-scale liquefied hydrogen terminal set to begin operations in 2030.
N-type wafer prices extend four-week slide amid weak demand, rising inventory concerns
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
JinkoSolar achieves world record efficiency of 27.79% for TOPCon solar cell
The Chinese manufacturer says Germany’s Institute for Solar Energy Research Hamelin (ISFH) has independently verified the result.
UK adds 1.9 GW of solar in 12 months
Latest government figures record 20.7 GW deployed PV capacity at the end of October 2025, up 10.4% in a 12-month period. Surge in contracts for difference (CfD) supported connections recorded in 2025 with more large ground-mount projects in the pipeline.
European solar manufacturing ‘considerably behind’ NZIA targets, says EU observatory
A report from the Clean Energy Technology Observatory finds that while the EU is a technology leader in PV inverters, trackers and mounting structures, its manufacturing capacity in solar ingots, wafers, cells and modules falls far behind targets set by the Net Zero Industry Act.
Longi achieves 33.35% efficiency for flexible perovskite-silicon tandem solar cell
The Chinese manufacturer said the tandem device was developed through a dual-buffer layer strategy that improves interfacial adhesion while preserving efficient charge extraction. The efficiency result was certified by the US Department of Energy’s National Renewable Energy Laboratory (NREL)
Efficient solar PV cooking with sand-based thermal energy storage
Scientists in Ghana have developed a device that combines a conventional solar PV-powered steam cooker with sand-based thermal energy storage. The system can achieve a thermal efficiency of 38.9% and has a payback period of 4.5 years.
