Overcoming thermal issues of vanadium redox flow batteries
Chinese scientists have analyzed reports of thermal issues with vanadium redox flow batteries (VRFB) and existing thermal management methods. They say the operating temperature should be maintained in the range of 10 C to 40 C to ensure VRFBs with high efficiency, weak side reactions, high electrolyte stability, and low crossover.
Big wafer benefits extend to n-type, says Trina Solar
China’s Trina Solar has published a white paper on its latest n-type TOPCon modules, with cost calculations and figures from demonstration projects. The Chinese PV manufacturer claims better performance from its 210 mm cells than with other n-type products based on smaller, 182 mm cells.
European PV equipment makers pitch machines to US solar manufacturers
A $1 billion to $1.5 billion US market opportunity awaits PV equipment manufacturers through 2030, a McKinsey & Company consultant said at a recent event for potential equipment buyers and sellers in Washington, DC.
Enphase demonstrates bidirectional EV charger
Enphase’s new bidirectional EV charger enables vehicle-to-home and vehicle-to-grid applications, and can be integrated with its home energy systems.
India confirms focus on green hydrogen, solar and battery manufacturing
India’s 2023-24 budget shows the government’s plans to support the domestic production of lithium battery cells.
Contractor kicks off tender for 7 MW of solar in Lebanon
DT Global, a US-based development firm, is seeking engineering, procurement and construction (EPC) contractors to build a PV plant with 5 MW to 7 MW of capacity in Lebanon.
Inverted perovskite solar cell with 24.1% efficiency
An international research group has developed an inverted perovskite solar cell with an active area of 9.6 mm2 by using polymer dipoles for interfacial engineering. It retained 96% of its initial power conversion efficiency after continuous maximum power point (MPP) tracking for 1,000 hours.
Only5mins! – Monetizing energy storage
Storage Hub founder Oliver Schmidt speaks with pv magazine about his outlook for battery energy storage pricing and the cost trajectory of electrolyzers. Schmidt’s new book, “Monetizing Energy Storage – A toolkit to assess future cost and value,” will be published by Oxford University Press in June.
Portugal installed 890 MW of solar in 2022
Portugal’s cumulative PV capacity hit 2.59 GW at the end of 2022, outpacing the growth of other renewable energy sources. The country failed to meet its own installation predictions, likely because some large-scale projects awarded in the 2019 and 2020 auctions ended up missing their commissioning deadlines.
Battery supply chain state of health
As the US Uyghur Forced Labor Prevention Act demonstrated, companies preparing to spend big on batteries are at risk of being blindsided by supply-chain-related legislation. Here are some tips on how US developers can anticipate policy curveballs.
