Analyze BESS: online diagnostics for safety, performance, and extended lifetimes
Learn more about how online diagnosis can be deployed and preventative maintenance systems put in place. Kai-Philipp Kairies, CEO at Accure, will draw on real-world data and actions taken, to demonstrate the power of the technology.
Brazil and Chile could lead charge to affordable green hydrogen
Falling electrolyzer costs driven by economies of scale, increased automation of production and the modularity of such systems will bring green hydrogen to a competitive cost with its fossil-fuel powered variants in a dozen markets by 2030, according to WoodMac.
The Hydrogen Stream: ‘China, Chile, Spain and Australia will lead the hydrogen economy’
The International Energy Agency said the four nations are on track to contribute 85% of the 18 GW of global renewables capacity which is set to be dedicated to green hydrogen production by 2026. Elsewhere, the Port of Valencia has unveiled a plan to install a green hydrogen supply station in the new year.
Ultra-thin silicon layers for 22.2%-efficient heterojunction solar cell
Scientists in the Netherlands fabricated a heterojunction solar cell with a layer of hydrogenated nanocrystalline silicon just three nanometers thick. The cell’s efficiency was measured at 22.2%, below the highest achieved with HJT cells, however, the researchers note that successfully incorporating this material into the cell stack will open many new doors for improvement.
KAUST achieves 28.2% efficiency for perovskite/silicon tandem solar cell
Saudi Arabian scientists have developed a perovskite sub-cell of a tandem device with a molecule that prevents the migration of ions into the perovskite film, even under humid conditions. The solar cell has an efficiency of 28.6%.
Singapore floating PV company targeting offshore expansion
Floating PV is a growing niche in the solar sector, but its offshore segment has proven more difficult to activate, largely because of the difficulty of open-water energy generation. Nevertheless, one company in Singapore, G8 Subsea, aims to leave the safety of harbors and reservoirs.
Fast charging for lithium-ion batteries needs a fix
Scientists in the United States placed fast charging for lithium-ion batteries under the microscope, finding that charging at higher rates can quickly damage the structure of a graphite anode, causing capacity loss even after a small number of cycles. By identifying the mechanisms causing this performance loss, the group can help point future research in the right direction.
Illustrating the n-type advantage
In a new white paper, Chinese PV manufacturer JinkoSolar demonstrates how its latest ‘Tiger Neo’ module, featuring the 182mm n-type TOPCon cells, achieves lower energy costs. Based on total project costs for various scenarios in China, the Middle East and Europe, Jinko calculates advantages arising from both the cell technology and its chosen wafer format.
The Hydrogen Stream: 8 GW green hydrogen project announced in Chile
Meanwhile, on the Iberian Peninsula, H2 Green Steel (H2GS) and Iberdrola plan to establish a 1 GW green hydrogen production facility, and Acciona and Plug Power want to deploy green hydrogen facilities across Spain and Portugal.
From sun to fork: How can circular agrivoltaics boost solar’s reputation and increase value creation for all?
What is agrivoltaics and how can it provide value for the solar industry and the wider community? Our upcoming pv magazine Webinar will discuss the different types of agrivoltaic projects and how they can become part of a circular economy.
