New research by Monash University identifies pre-treatment of lithium-ion batteries as an overlooked recycling strategy in the recovery of valuable metals lithium, nickel, and cobalt.

Bifacial solar panels, string inverters and advanced tracking systems are fast becoming the technologies of choice for developers of large-scale solar according to new data provided by Spain-based software company and analytics provider RatedPower.

In an interview with pv magazine, Empa scientist Mirjana Dimitrievska explains that the CIGS photovoltaic technology, while promising for efficiency and flexible applications, faces persistent challenges in scaling lab-level performance to cost-effective, high-throughput industrial production, limiting its ability to compete with crystalline silicon. She also emphasizes that long-term stability, reliability, and material sustainability, rather than peak efficiency, are crucial for commercial viability, especially in niche markets like building-integrated and lightweight PV.

The energy storage efficiency of 12 solar storage systems with capacities of 5 kW or 10 kW has been put to the test, including several new products, all of which achieved efficiency class A. The latest interation of the annual study also examined efficiency losses when storing electricity from the grid and took a closer look at the warranty conditions of the devices.

Output from Australia’s large-scale renewable energy sector continues to climb with the nation’s utility PV and wind assets generating a total of 5.0 TWh in February, delivering an 11% increase on the same time last year.

The lab-scale, near-white heterojunction solar cell uses nanoclay-based scattering layers combined with dielectric multilayer films to preserve power conversion efficiency while enhancing visual appeal. The researchers report optical losses of less than 1% at a 50% clay volume fraction, which are significantly lower than those observed with textured glass.

Australia’s national science agency has launched a major revamp of its renewable energy research facility in Newcastle to provide new capacity for researchers and industry to test how technologies such as solar, wind, batteries and electric vehicles can integrate reliably into the grid.

UNSW researchers have developed an intrinsic-adjusted single-diode model that explicitly accounts for radiative and Auger recombination, improving I–V curve accuracy and reducing root mean square error by up to a factor of three. The model is claimed to better predict performance near open-circuit voltage and maximum power point.

Analysis from BloombergNEF finds the levelised cost of electricity (LCOE) of a typical fixed-axis solar farm increased by 6% year-on-year in 2025 to stand at $55/MWh, but innovation and competition are expected to see costs fall by 30% through to 2035.

An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.
