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 Germany’s Fraunhofer FEP have unveiled a dirt-repellent coating for solar panels. The material is reportedly able to acquire superhydrophilic properties at night and wash away accumulated dirt with the aid of beads of moisture.

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.

Scientists in Austria have developed a long-term energy storage system that uses regenerative braking to adjust the descent speed of sand in mine shafts and generate electricity.

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.

US-based Salgenx has developed a scalable redox flow battery with two separate tanks of electrolytes, one of which is saltwater. Unlike other flow batteries, the new device is membrane-free, promising big gains at the levelised cost of storage level.

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.

An educational event series aimed at upskilling engineers to enter the hydrogen industry is launching in February in Melbourne. The Hydrogen Industry Technical Series 2023 is being organised by the Victorian divisions of the Australian Institute of Energy and Engineers Australia.
