Weekend Read: Connecting HJT

The application of busbarless cell interconnection approaches could unlock the potential of heterojunction (HJT) technology, primarily by reducing the historically high silver usage of negatively-doped, “n-type” cell technology. As HJT manufacturing increases, a wave of applications may very well be on the horizon.

New research claims PV outperforms afforestation in combating climate change

Scientists from Israel have calculated how long it would take for PV plants and afforestation projects to offset their warming impacts caused by the darkening of land. The results showed that in drylands, PV fields could be over 50 times more efficient than afforestation.


Weekend Read: Consolidating growth in Africa

Across Africa, rooftop solar is stepping in to fill the void as fears of non-payment and inflation-reduced donor funding dampen enthusiasm for big solar. Commercial and industrial (C&I) arrays are leading the charge, driving consolidation in markets overstocked with startup and mid-size installers.


Quasi-solid-state magnesium-ion battery achieves energy density of 264 Wh/kg

Researchers at the University of Hong Kong (HKU) have developed a quasi-solid-state magnesium-ion battery with a voltage plateau at 2.4 V and an energy density of 264 Wh/kg. It surpasses the performance of current magnesium-ion batteries and almost matches the performance of lithium-ion batteries.


Europe should produce its own green hydrogen

As the cost of generating clean energy continues to fall, producing green hydrogen in Europe, rather than importing it from Africa – with all the transport costs and raised carbon footprint that would entail – is beginning to look like an increasingly viable option.


Weekend Read: Install grid-connected solar, rinse, repeat

Will a redeployable solar and energy storage solution be the answer to unreliable grid electricity across much of Africa, as its developer proposes? Or will it merely be a temporary solution that will see cash-strapped utilities kick the can of universal energy access further down the road?

Solar on farmland, rather than nuclear, should shape Italy’s energy mix

Matteo Salvini, head of one of the parties in Italy’s coalition government, last year pointed to a future energy system based on rapidly deployed nuclear generators, sowing further doubt for renewables investors. Patrick Donati, founder of Italian independent power producer (IPP) Terrawatt, explains why nuclear will have no future in his homeland and why installing panels on a limited amount of farmland – rather than costly agrivoltaics – could be a necessary short-term climate fix.


Lhyfe expanding hydrogen production with focus on offshore wind

Jérémy Langon, head of energy sourcing and site development for Lhyfe, tells pv magazine that the France-based hydrogen producer is focusing on a combination of renewable sources, including offshore wind, to scale up hydrogen production.


The ‘next big thing’

The PV industry in Southeast Asia has come a long way since guest author Ragna Schmidt-Haupt, partner at Everoze, reported on solar financing innovation in the region more than a decade ago. In this article, she outlines five factors for success, the newest of which has the potential to become a game changer, and not only in Southeast Asia.

Weekend Read: Data harvesting

Mounting system manufacturers back their technology but farmers still have questions about the realities of solar on agricultural land. Ramping up research on how agrivoltaics affect farming yields could provide vital answers.
