BYD unveils 14.5 MWh storage system, world’s largest yet
China’s EV giant has unveiled the 14.5 MWh DC “Haohan” single-unit DC block with record-breaking capacity to challenge next-generation energy storage market.
AlphaESS releases liquid-cooled ESS for commercial, industrial use
The Chinese storage manufacturer said its new energy storage system has a capacity of 261 kWh per cabinet. It can be expanded up to 50 units in parallel, scaling to multi-MWh projects.
China completes 1 GW solar-wind-storage complex in Qinghai desert
Chinese conglomerate CRRC has commissioned a 1 GW hybrid project in Qinghai, combining 700 MW of solar, 300 MW of wind, and 100 MW/400 MWh of storage with Trinasolar’s Vertex tunnel oxide passivated contact (TOPCon) modules.
China connects largest battery-supercapacitor hybrid storage plant
China has connected a 100 MW hybrid energy storage facility to the grid. It integrates supercapacitors and lithium-ion batteries, setting a new benchmark for ultra-fast frequency regulation services.
Scientists boost organic solar cell efficiency using polymer zwitterions
A research team based in China and the United States has developed electroactive polymer zwitterions to modify zinc oxide interlayers in organic solar cells. Their work was found to passivate defects in organic solar cells, helping to improve device performance and stability.
Chinese scientists build 10.48 cm2 kesterite solar module with 10.1% efficiency
The efficiency result was confirmed by the U.S. National Renewable Energy Laboratory. The module was fabricated with 13.4%-efficient kesterite cells designed with high film porosity and uniformity.
Hands-on with the Bluetti Apex 300 portable power station
A hands-on with the Apex 300 reveals it has unique strengths for those looking for portable power in a design that is made to expand through accessories.
Improving diamond wire sawing to reduce kerf loss in solar wafer production
Researches in China have sought to assess how lateral vibration in diamond wire sawing can increase kerf losses in solar wafer manufacturing and have developed a predictive model than can reportedly help reduce them. Their analysis showed that, with constant sawing parameters, smaller wafers suffer from greater excess kerf loss.
Floating PV system with ring-like floater geometry
Scientists in China have investigated the hydrodynamic performance of a novel modular floating photovoltaic system. They did so using a novel hybrid approach, which integrates viscous-flow effects from computational fluid dynamics into a potential-flow solver. They analyzed the new system with varying numbers of panels, either in a single chain or a parallel configuration.
GCL to raise $450 million for China polysilicon consolidation plan
GCL plans to raise $450 million to aid consolidation in China’s polysilicon sector and support the shift from tunnel oxide passivated contact (TOPCon) to back-contact solar products.
