Malaysian researchers have developed a system that can absorb heat from PV modules and transmit it to a nanofluid, in order to transform it into thermal energy and use it for different applications. The panels have an overall efficiency of 89%.

A research team at the Australian National University have claimed an efficiency of 30.3% for a tandem solar cell made by mechanically stacking a perovskite cell and a silicon cell. The achievement meets the first of three 2030 “stretch goals” set by the Australian government.

Solar and storage analyst Sunwiz is predicting an inversion of many of the trends that dominated the industry in 2022. While rooftop solar has bounced back after a disappointing year, Sunwiz founder Warwick Johnston tells pv magazine Australia, the utility segment’s position looks dire.

Scientists in Sweden have compared AC and DC topologies in PV-powered buildings using battery storage. They have found that DC distribution systems can achieve energy savings when they are combined with solar-plus-storage systems.

New data from Cornwall Insight Australia’s EV uptake model shows that under an extreme scenario, 22 million electric vehicles (EVs) are expected to be part of the National Electricity Market (NEM) states’ fleet by 2052.

The two dominant methods used in the industry to estimate soiling levels on solar projects go some way in mitigating losses, but there is plenty of scope for more accurate observation, as NRG Systems’ Alexandra Arntsen reports.

An international research group claims that raw materials and land availability do not present a real barrier for a global energy system with solar at its centre. They said that forecasts for PV growth should not have their axis on utility-scale power plants and instead consider vertical PV, agrivoltaics, and floating PV as the source of future big market volumes.

Last year was a tricky one for solar, with each segment from residential to commercial to utility behaving quite differently. The industry trends have been laid out in Sunwiz’s latest Australian PV Report and pv magazine Australia takes a dive into what happened and what there is to learn.

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.
