JinkoSolar achieves 26.1% efficiency for n-type TOPCon solar cell

JinkoSolar has set another world record for n-type solar cell efficiencies with its TOPCon technology, this time reaching 26.1%. The new record was confirmed by China’s National Institute of Metrology.

Weekend read: Software to serve up more solar

Enabling future energy flows at the lower-voltage distribution level? Unlikely. Wide-scale hardware upgrades would cost billions if not trillions, especially in Australia’s far reaches. Software and digital solutions are identifying new cost-effective ways of letting more sun into the grid.

Novel anode material paves way for 15-minute EV charging

US researchers have developed a novel fast-charging battery anode material, and GM has revealed a new focus on battery R&D. The European Parliament, meanwhile, has issued a number of proposals for alternative fuels infrastructure.

Pairing batteries with rooftop solar

A growing number of residential solar projects include energy storage batteries. In the first part of this series, we look at the backup power feature of batteries.

Elon Musk’s battery packs or Twiggy Forrest’s green hydrogen?

The battle of the billionaires has become the stuff of headlines. The world’s richest man, Elon Musk, has gone head-to-head with Australia’s richest man, billionaire Andrew “Twiggy” Forrest.

Weekend read: Islands in the sun

Islandable microgrids are a growing niche, especially in remote regions at the end of electricity networks or parts of the world prone to natural disasters and outages. Renewably powered microgrids can provide a community with more stability and operate independently, so vulnerable regions are not reliant on distant sources of generation, as was the case during Australia’s Black Summer bushfires of 2019-20, when communities were left powerless. From California to Australia’s southern coast, the study and deployment of microgrids is on the rise. pv magazine’s Blake Matich takes a look.

FFI & Deutsche Bahn to modify diesel engines for hydrogen locomotives, biotech startup targets hydrogen production from $1.5/kg

Cemvita claims it can produce hydrogen at the “lowest possible cost,” Deutsche Bahn and Fortescue Future Industries have announced plans to jointly modify diesel engines for locomotives, and the Canadian province of Alberta has started promoting its hydrogen potential in Japan.
