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.
Japan publishes new guidelines for flexible solar cell installations
Japan’s New Energy and Industrial Technology Development Organization (NEDO) says its new design and construction guidelines for flexible PV and perovskite solar installations will help ensure the safety and reliability of systems deployed on low-load rooftops and wall surfaces where conventional panels cannot be installed.
India’s PV module manufacturing capacity tops 210 GW
India added 119 GW of solar module capacity and over 9 GW of cell capacity in 2025, bringing total capacities to about 210 GW and 27 GW, respectively, according to Mercom India. Growth was driven by strong project demand and policy support, although supply-demand alignment is expected later in 2026 as domestic cell production ramps up.
Solar-to-X could redefine Iran’s energy future
Iran is widely known for its oil and gas resources, but its strongest long-term energy asset may be the sun. New research shows how solar PV could drive a cost-competitive transition across power, heat, transport, industry, and desalination, while opening the door to a broader Solar-to-X Economy.
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.
Advait Greenergy opens 30 MW electrolyzer assembly facility in India
Advait Greenergy has launched a 30 MW electrolyzer assembly facility in Gujarat, India, with plans to scale capacity to 1 GW annually.
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.
India’s 35 GW of renewables at risk of curtailment, warns Crisil Ratings
Crisil Ratings says rapid renewable energy additions and slow grid expansion could expose more than 35 GW of capacity to curtailment in India.
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.
