For a long while, it looked as if hydrogen fuel cells would be the technology of choice for emissions-free road transport. However, truck manufacturers and freight forwarders recently turned their attention to battery-electric vehicles. This will require special charging technology and PV looks set to play an important role.

Berlin-based Boreal Light has developed water desalination tech powered by PV for off-grid applications. The solution uses 460 W solar panels from Chinese module manufacturer DAH Solar and produces clean water from direct seawater at a cost of €0.50 ($0.78)/m3.

Radovan Kopecek, the co-founder and director of Germany’s ISC Konstanz, says interdigitated back contact (IBC) tech could account for half of the global market for solar modules by 2030. He says IBC will start to dominate once TopCON and HJT get stuck at certain efficiency limits, and he believes TOPCon will be the first victim.

Trina Solar says its industrial tunnel-oxide passivated contact (i-TOPCon) solar cells, based on 210 mm wafers, have started rolling off the production line at its 8 GW factory in China. It will use the n-type cells to produce its new Vertex N modules, with power outputs ranging up to 605 W, and an efficiency rating of 22.4%.

New research highlights the crucial role of R&D in improving solar cell efficiency. The researchers discovered that it is theoretically possible to measure the promise of new solar cell technologies at any stage of development.

Major shopping centre landlord, Vicinity Centres, has teamed up with Enel X to potentially deploy up to 50 MWh of cumulative energy storage capacity. The partnership kicks off with two battery fit outs in Victoria and New South Wales, and follows a $73.2 million (USD 50 million) solar rollout across Vicinity’s shopping centres.

A US research team has developed a new technique to produce hydrogen from sunlight and water. It works in an indoor environment and uses pure water, concentrated solar light, and an indium gallium nitride photocatalyst.

New research from the University of New South Wales outlines the need for solar cell and module makers to reduce or eliminate the use of silver in their products. Based on expected PV growth, in line with climate change commitments, solar manufacturers would require at least 85% of global silver reserves, according to the new study.

Chinese manufacturer Huasun launched a new line of five heterojunction (HJT) solar modules in 2022, with power outputs ranging from 680 W to 700 W. The company has now added a new 715 W module to the series.

Before Puerto Rico had a chance to recover from Hurricane Maria, in 2017, it was rocked by earthquakes and then, in September 2022, the island was struck again – this time by Hurricane Fiona. These disasters severely impacted Puerto Rico’s infamously fragile power grid, but have emboldened local communities to take power into their own hands through solar and battery storage, and increasingly in the form of microgrids. Compelled by catastrophic circumstances, Puerto Rico must now push toward energy resilience and in the process may see itself become a model not just for other islands, but mainland grids as well.
