Widespread green hydrogen deployment will be key to achieving stringent climate targets, and German hydrogen demand is set to grow from the 80 TWh range in 2030 to between 400 TWh and 800 TWh by 2050, according to a new joint study by several Fraunhofer-related entities.

Module manufacturers have once again adjusted their prices upwards. This is already the third or fourth price increase in the last six months, and there is no end in sight, writes Martin Schachinger of pvXchange. But why is it so hard to achieve long-term, sustainable development in the global solar market, at least on the part of manufacturers? Few other industries are so turbulent, with constant swings between excess supply and bottlenecks, between price collapses and price rises – and always to the breaking point of the market. Yet again, planning security is out the window.

As PV manufacturing lines continue to get larger, keeping track of the measurement data that’s vital for quality and process control becomes an ever more herculean task. Flashing equipment supplier h.a.l.m. has developed a software solution that keeps all of this data in one place and provides operators with a real-time view of production line performance and quality. pv magazine caught up with Managing Director Michael Meixner to discuss the latest on big data in PV manufacturing.

A German PV system owner has developed a simple solution intended at preventing the birds from nesting under the modules.

Production on the new module, called Q.Tron, is expected to begin this year. The product is described as an evolution of the company’s Q.antum cell technology.

The most powerful of the two products has a power output of up to 380 W and an efficiency of 20.4%. For both panels, the temperature coefficient is -0.37%. The German manufacturer said the modules are produced at its manufacturing facility in Dresden.

Graphite’s pivotal role in electric-vehicle battery technology is coming under increasing scrutiny. Graphite is almost exclusively produced in China, and while the processing of the mineral poses serious environmental issues, the alternatives appear costly. Ian Morse looks at what’s next for critical graphite supplies.

Hydrogen and hydrogen-based fuels will not be able to move forward fast enough to replace fossil fuels and tackle climate change, according to a German-Swiss research team that claims direct electrification alternatives are cheaper and easier to implement. The scientists cite too-high prices, short-term scarcity and long-term uncertainty, as the main reasons for their skepticism, which has caused a stir in academic circles.

German scientists have proposed a new design for stacks used in redox flow batteries. Through a powder-to-roll process, a device that weighs 80% less than a conventional stack was fabricated.

Researchers in Germany claim to have overcome the primary hurdle in the development of large-area perovskite PV modules – scaling up from the cell to the module level. They achieved an efficiency of up to 16.6% on a module surface of ​​more than 50 centimetres squared, and 18% on a module with an area of 4 centimetres squared.
