Researchers have found that the performance loss of TOPCon modules due to UV radiation is less severe than initially feared. Moreover, the defect is potentially reversible.
SMA's new life cycle assessment, certified by DEKRA and conducted by the Fraunhofer Institute, provides a clear picture of the environmental impact of the Sunny Central UP inverter across its lifespan.
In the new production process, the individual powders are sintered, i.e. pressed together under high pressure. This is quick and scalable for industrial processes.
In the newly organised development centre, module manufacturers can use extensive equipment to further develop their technologies. Fraunhofer ISE supports manufacturers in the further development of their products.
Sodium-ion storage units have advantages over lithium-ion batteries, but also limitations. A new study shows which technological and market development can be expected and where the storage units could be used.
The Institute was also involved in the development of an IEC standard for the testing of arc detectors. The modular test rig is able to perform the tests of the inverters according to this standard.
The partners in the Demobat project have not only developed a flexible system to separate the individual components of the batteries from each other, but also a way to recover the raw materials they contain from the black mass.
In the Amalis 2.0 project, researchers are working on innovative lithium-air batteries. These can theoretically store ten times as much energy as conventional lithium batteries for the same weight. However, chemically stable electrolyte fluids are still lacking.
Fraunhofer ISE has developed a laser process that flexibly interconnects Perc and Topcon solar cells without busbars through an aluminium foil. The so-called Foilmet technology does not require conductive adhesives or solder. This reduces silver consumption by 30 per cent.
Modules of IBC Solar's own brand have been shown to have a particularly high performance-stability in Fraunhofer CSP's LeTID test.
Rock Tech Lithium has agreed to collaborate with Fraunhofer Umsicht and supply chain tracking company Circulor to provide carbon-neutral lithium from Europe.
A three-phase inverter that operates more quietly, integration of Fraunhofer charging points, a new mounting system for metal roofs and glass-free solar modules that weigh next to nothing. Here are our top products of the week:
An IT backend that integrates Fraunhofer charging points, a string inverter for any weather, solar terrace roofs and carports and a heat pump that works without gas using PVT collectors. These are our top products of the week:
