Reliance signs alkaline electrolyzer deal with Norway’s Nel
Through the agreement, Reliance gets access to Nel’s technology platform for manufacturing alkaline electrolyzers.
IEA-PVPS launches action group on agrivoltaics
IEA-PVPS is poised to launch a new format for expert engagement. It will include an action group on agrovoltaics, as well as a collaborative effort to match agriculture and solar generation. It aims to unlock the potential of agrivoltaics, optimize land use efficiency, enhance agricultural resilience to climate change, and foster social consensus for solar development.
U.S. scientists demonstrate 25%-efficient perovskite-cadmium tandem solar cell
The researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.
China switches on first large-scale sodium-ion battery
China Southern Power Grid has deployed a 10 MWh sodium-ion battery in China’s Guangxi Zhuang region. It is the first phase of a 100 MWh project.
Solar-hydrogen solution rolled out for off-grid settings
A new mobile power generator that combines solar and renewable hydrogen to provide zero-emissions power for remote and off-grid applications has been unveiled by Australian startup H2PowerBox.
Optimizing solar investments
In India’s quest for a sustainable energy future, solar asset management emerges as a key to optimizing investments, ensuring reliability and maximizing productivity.
Algorithms to detect underperforming rooftop PV panels
Australian researchers have developed multi-stage algorithms to remotely detect and accurately diagnose underperforming solar panels in residential and commercial PV systems.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.
New water circulation tech promises lower PERC solar cell manufacturing costs
A German team developed models to illustrate water-saving potential in PERC silicon solar cell manufacturing based on a circular approach and commercially available technology. In the case of a 5 GW fab, water savings of up to 79% and wastewater discharge reductions up to 84% could be achieved, a “significant” improvement compared to a reference scenario.
Scientist hails commercial feasibility of Saudi Arabian hydrogen city plan
Alberto Boretti was a senior research professor at Prince Mohammad Bin Fahd University in 2021 when he first started discussing the idea of a hydrogen city in Al Khobar, Saudi Arabia. The New Zealand-based independent tells pv magazine that it is now commercially feasible, as the city’s 200 MW of energy demand would necessitate 1 GW to 1.3 GW of solar and wind capacity, 509 MW to 997 MW of electrolysis capacity, and 145,000 MWh of hydrogen storage capacity.
