Perovskite-silicon tandem tech tested in solar race car

A team of Dutch university students under the banner Top Dutch Solar Racing has installed perovskite silicon tandem cells in its entry in the 16th edition of Bridgestone World Solar Challenge. The upcoming race is a six-day, 3,000km expedition across Australia, from Darwin to Adelaide.

Germany, Austria hit by multiple solar battery fires linked to LG

pv magazine has learned that five solar-related fires in Germany and Austria occurred in late September. Photographs show that two of the blazes were likely caused by residential batteries manufactured by LG.

1Komma5° announces TOPCon solar module factory in Germany

1Komma5° says it plans to start production at a new TOPCon solar module factory in Germany from next year. The Hamburg-based startup aims to achieve an annual production capacity of 1 GW, with further expansion targets set to reach 5 GW by the year 2030.

New method to take PV plant measurements in the field

Spanish researchers claim to have established new measurement methods to assess the performance degradation of PV modules without the need for removing and reinstalling the tested PV modules from their operating positions. The new approach is claimed to increase productivity in PV plant quality control activities.

Swedish startup to use green hydrogen plasma in pilot reactor for solar grade silicon

Encouraged by lab results and a feasibility study, Swedish startup, Green14, in collaboration with Sweden’s Royal Institute of Technology (KTH) plans to build a pilot-scale reactor to make solar grade silicon with a hydrogen plasma process. The company sees the pilot as a step towards using a more sustainable method to produce solar grade silicon for the PV industry at its own gigawatt-scale plant.

Researchers developing cheap hydrogen storage

Oxford Institute for Energy Studies researchers have developed a cost-effective material to absorb hydrogen at non-cryogenic temperatures, which they consider optimal for fuel cell storage systems.

EV sharing to provide stationary storage services via V2G tech

We Drive Solar and MyWheels have announced plans to transform the Dutch city of Utrecht into the world’s first municipality with a “neighbourhood battery on wheels.” The system will feature 25 Ioniq 5 vehicles equipped with vehicle-to-grid (V2G) tech from Hyundai Motor.

Low-temperature processes to reduce silver use in tandem perovskite-silicon solar cells

Researchers from Germany’s Fraunhofer ISE developed new techniques to reduce silver consumption in tandem perovskite silicon solar cells and heterojunction silicon PV devices. The new processes relate to cell metallisation and module interconnection.

World’s first green hydrogen plant to heat steel

Hitachi Energy has delivered a modular solution to electrify a 20 MW electrolyser to produce hydrogen to heat steel before rolling, while Enapter has unveiled its AEM electrolysers for industrial and refuelling pilot projects.

Lithium-ion batteries: NMC, LFP, LTO – what’s the difference?

With battery storage such a crucial aspect of the energy transition, lithium-ion (li-ion) batteries are frequently referenced but what is the difference between NMC (nickel-manganese-cobalt), LFP (lithium ferro-phosphate), and LTO (lithium-titanium-oxide) devices and their underlying chemistry?
