Researchers from the University of Adelaide, along with international partners, have successfully used seawater with no pre-treatment to produce green hydrogen. The team did this by introducing an acid layer over the catalysts in situ. “We have split natural seawater into oxygen and hydrogen with nearly 100% efficiency… using a non-precious and cheap catalyst in a commercial electrolyser,” University of Adelaide’s Professor Shizhang Qiao said.

UK scientists have discovered that second-life batteries could provide a lower levelised cost of electricity (LCOE) than conventional batteries in school buildings equipped with PV in East African schools. They said the cheapest system configuration uses either 7.5 kW or 10 kW of solar with 20 kWh of storage.

Scientists from Australia are among an international team of researchers that predict lightweight, high-performance perovskite solar modules could soon become competitive with crystalline PV modules in the residential segment, as such products will likely have lower manufacturing and balance-of-system costs in the future.

Researchers from Victoria’s Deakin University say they have successfully tested a new process that can safely and effectively extract silicon from end-of-life solar panels, then convert it into a nano material worth more than $45,000 (USD 31,500) per kilogram that can be used to build better batteries.

Australian climate tech platform Acacia will launch a new solar feature enabling customers to get a digital solar quote, as well as estimated financial and carbon savings, without speaking to any sales people. The company says the tool is in response to what are often poor buying experiences in the solar sector.

Canadian scientists have developed a new way to measure the energy yield of bifacial PV systems. They said they considered the spectral albedo of ground cover like snow and sand to predict energy gains of up to 2%, in comparison with the International Electrotechnical Commission (IEC) standard.

An international consortium led by Italy’s Eurac Research launched the Symbiosyst project to adapt PV modules, mounting structures, and maintenance technologies to the needs of various crops in agrivoltaic installations in different climates.

French energy giant TotalEnergies studied the impact of solar panels on crops in order to develop a repository of agronomic benefits. The initial results show an increase in agricultural yields on field crops and a reduction in water stress.

A new report by the International Energy Agency’s Photovoltaic Power Systems Programme (IEA-PVPS) estimates that lost revenue from PV module soiling amounts to more than €3 billion ($4.6 billion) per year – an amount that is only set to increase as PV systems grow larger and more efficient.

Perovskite solar cells have created excitement in recent years, given their potential to improve virtually every area of PV, but we have yet to see such devices produced at scale. Scientists in Australia have outlined some of the challenges holding them back.
