Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

The Industrial Technology Research Institute (ITRI) and United Renewable Energy (URE) have developed a solar panel that can be easily dismantled to simplify the recycling process. They claim 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.

Energy infrastructure company CuString has secured federal environmental approval for the massive CopperString 2.0 transmission link that would stretch across north Queensland, helping to unlock large-scale solar and wind investment along with large deposits of minerals key to the energy transition.

German researchers have created an algorithm to predict and identify string yield losses or underperforming strings without additional weather data. It could be used to inspect modules, strings, arrays, inverters, and transformers.

Sun Cable is seeking to develop the world’s biggest intercontinental solar and storage project, and has now inked a deal with the Indonesian government that could unlock more than $170 billion (USD 115 billion) in renewable energy generation and transmission operations in the archipelago.

Chinese manufacturer JinkoSolar’s newest PV module has an efficiency rating of 23.86%. It is based on its TOPCon mono cell technology, which achieved a record efficiency of 26.1% in October, as confirmed by TÜV Rheinland.

Australia’s first hybrid solar and renewable hydrogen microgrid has officially launched as green hydrogen production began at Horizon Power’s demonstration plant in the coastal community of Denham in Western Australia’s Gascoyne region.

A team of scientists from the University of Cambridge have developed lightweight floating photocatalyst devices that produce green hydrogen and syngas. The leaf-like photoelectrochemical devices show potential for scalability.

Residential, commercial and industrial solar generation in South Australia has returned to normal operations following heavy curtailment by authorities working to stabilise the grid after storms caused extensive damage to transmission infrastructure.

New Zealand’s solarZero says it aims to provide fast, sustained reserves with its virtual power plant of 10,000 household battery systems. Meridian Energy, meanwhile, has secured approval for a 100 MW battery energy storage system – the country’s largest such system to date.
