Grid-forming inverters boost grid stability, say US researchers
The Kauaʻi Island Utility Cooperative in Hawaii, which deployed storage before grid-forming inverters became available, became a test case for diagnosing grid issues that can arise with older grid-following inverters, and how grid-forming inverters can stabilize a grid.
Mirai Solar develops lightweight solar panel for agrivoltaics
While completing pilot projects in the U.S. and Europe, Mirai Solar has certified its lightweight PV module designed to work as a shade screen in agrivoltaics applications, such as greenhouses.
Solar module prices lagging behind soaring silver costs
Solar manufacturers are facing rising cost pressure as silver paste now accounts for up to 30% of total cell production costs. OPIS analyst Hanwei Wu tells pv magazine that module producers currently have limited ability to raise panel final prices, which is accelerating efforts to reduce silver use across all mainstream cell technologies.
Chinese scientists push selenium solar cells beyond 10% efficiency
Researchers at the Chinese Academy of Sciences have set a world record for selenium solar cells, achieving 10.3% efficiency for the first time above the 10% threshold. The breakthrough was enabled by optimized charge-selective contacts, light-driven crystallization, and post-deposition annealing, producing stable devices with a 1.03 V open-circuit voltage.
Luxembourg revamps subsidies for solar on residential buildings
Luxembourg’s new subsidy scheme for solar installed on residential buildings by an approved installer deducts the financial aid from the installer’s invoice, meaning customers no longer have to wait for reimbursement.
Australia adds 7 GW of renewables in 2025, stays on track for 2030 target
Australian Federal Energy Minister Chris Bowen says the country is on track to meet the government’s flagship target of 82% renewable energy by 2030 after solar, wind, and other renewables supplied about 50% of all power in the electricity grid in the final quarter of 2025.
Swiss researchers improve electrolyte design for long-life solid-state batteries
A Swiss research team has developed a low-temperature sintering and interface-coating process that significantly improves the durability of argyrodite-based solid-state batteries. The approach delivers high ionic conductivity and long cycle life, retaining 75% of capacity after 1,500 cycles.
Adani Green unit to supply solar-wind power to Asahi India Glass
An Adani Green Energy subsidiary has signed agreements to supply 20.8 MW of hybrid solar and wind power to Asahi India Glass from projects in Gujarat.
