Thermochromic bifacial PV glazing system for reducing building cooling loads
Researchers in Hong Kong Hong Kong fabricated a thermochromic bifacial photovoltaic glazing system prototype that passively regulates solar heat gain while harvesting energy from both sides. Experiments and simulations showed it significantly reduces cooling loads and indoor temperatures while boosting electricity generation.
China’s new five-year plan deepens shift toward focus on renewables system
China’s 2026 to 2030 policy plan elevates clean electricity as a central driver of economic growth, with greater emphasis on system integration and industrial use.
Samduo launches residential AC-coupled plug-in storage systems
The Chinese manufacturer said its new Nex E6000 and Nex E6000H storage systems combine a 6 kWh battery, an inverter, and an integrated energy management system, with scalable design allowing multiple units to be networked for higher capacity and coordinated energy sharing.
US says China not undercutting domestic battery anode makers
The US International Trade Commission (ITC) has blocked the imposition of anti-dumping and countervailing duties on Chinese active anode material (AAM), providing a massive sigh of relief for the domestic battery storage sector.
Discovery of passivating pinholes in TOPCon solar cells paves the way for higher efficiencies
DAS Solar and Hebei University have identified two types of pinholes in TOPCon solar cells: harmful recombinational pinholes, which lack oxygen and cause carrier recombination, and beneficial passivating pinholes, which retain oxygen to enable efficient tunneling while maintaining interface passivation. Their work shows that optimizing oxide layer formation, back-surface polishing, and polycrystalline silicon deposition can increase passivating pinholes, boosting device efficiency and guiding industrial cell design.
