Weekend read: Making tandem cells stack up
Perovskite tandem technology is shaping as the route to PV cell efficiencies well beyond 27%. But building the tandem stack in a way that can be scaled into gigawatt production is not a trivial challenge, says Sebastian Gatz, VP photovoltaics for German equipment supplier Von Ardenne.
Cost comparison between lithium batteries, fuel cells, reversible solid oxide cells as storage for off-grid rooftop PV
Scientists in the United Arab Emirates have looked at how off-grid rooftop PV could be combined with batteries, fuel cells or reversible solid oxide cells for energy storage. The modelling assumed a typical commercial building in Los Angeles.
Trina launches grid-scale storage solution
Trina Storage’s new 2.1 MWh DC All-New Elementa solution is a modular LFP battery cabinet with a plug-in concept to connect multiple units. The company is ramping up battery manufacturing capacity to strengthen vertical integration, given supply chain risks throughout the world.
LG Energy Solution unveils new battery storage solutions, moves to LFP
South Korean battery manufacturer LG Energy Solution presented its latest innovations at the Smarter E event in Munich last week. It also announced its transition from nickel-manganese-cobalt (NMC) battery chemistry to lithium iron phosphate (LFP) in its future products.
Global annual solar deployment to hit 1 TW by 2030
Major players in the solar industry, such as LONGi Solar, are projecting accelerating growth in the near term.
Water ‘secret ingredient’ in new processing mechanism for perovskite nanocrystals
An unlikely union has been discovered by members of ARC Centre of Excellence in Exciton Science, who have found a way to control the growth of phase-pure perovskite crystals for next-generation photovoltaics using water.
Smarter E products at a glance
pv magazine summarises the products we covered at the recent Smarter E exhibition, in the first of a series of reports on all of the new releases from the annual trade fair in Munich, Germany.
Hydrogen fuel cell without precious metals developed, Australia’s global importance underscored in Rotterdam
A team of researchers from the University of Wisconsin-Madison, Cornell University, and Wuhan University have presented a completely precious metal–free alkaline fuel cell with enhanced performance using a carbon-coated nickel anode. Meanwhile, the Port of Rotterdam has offered to supply northwestern Europe with 4.6 million tonnes of hydrogen by 2030. According to RMI, Europe will import green hydrogen between 2024 and 2030. RenewableUK sees room for hydrogen exports from the UK to the EU.
Hanwha Q Cells to build US solar module factory, expand cell capacity in South Korea
Hanwha Q Cells plans to build a 1.4 GW solar panel factory at an undisclosed location in the United States. It has also announced plans to expand its cell capacity to 5.4 GW in South Korea. CEO Justin Lee spoke to reporters at the Smarter E event about the company’s plans and current supply chain issues.
Solar shines bright as world eyes record renewables growth
The International Energy Agency expects the global expansion of solar PV, wind power and other renewable energy technologies will continue to defy rising costs and supply chain bottlenecks to reach triple-digit growth this year with solar additions forecast to reach almost 200GW.
