Sydney, Australia (SPX) Oct 09, 2025 A University of Sydney-led team has achieved a new global milestone in solar energy, developing the largest and most efficient triple-junction perovskite-perovskite-silicon tandem solar cell ever reported. Led by Professor Anita Ho-Baillie, John Hooke Chair of Nanoscience at the University of Sydney Nano Institute and the School of Physics, the project achieved a certified steady-state pow

Washington DC (UPI) Oct 6, 2025 The Environmental Protection Agency was sued Monday for terminating $7 billion in "Solar for All" grants, intended to help low-income communities install solar panels on homes. The group of plaintiffs - made up of solar energy companies, labor unions and homeowners - filed the lawsuit in federal court in Rhode Island. They accused the EPA of ending the program, in violation of federal

Los Angeles CA (SPX) Oct 09, 2025 Researchers have uncovered how soil communities can bank sunlight as usable energy long after nightfall. A team from Kunming University of Science and Technology and the University of Massachusetts Amherst reports a bio-photovoltage soil-microbe battery that stores solar charge and later drives the breakdown of antibiotic pollutants without light. In lab tests, common soil bacterium Bacill

Sydney, Australia (SPX) Oct 09, 2025 Australia's world-leading rooftop solar adoption is generating a mounting waste challenge as many photovoltaic systems are retired early and routed to landfill. A University of South Australia team outlines how reuse standards, incentives, testing and certification could extend panel lifetimes and shrink solar's environmental footprint. The study led by UniSA PhD candidate Ishika Chhillar

Berlin, Germany (SPX) Oct 09, 2025 Scientists at Kaunas University of Technology (KTU), working with international partners, report one of the highest efficiencies yet for fully inorganic perovskite solar cells and, crucially, show they can run stably for hundreds of hours, narrowing the gap with commercial silicon. "Perovskite solar cells are one of the fastest-growing solar technologies in the world - they can be lightweight, t

London, UK (SPX) Oct 09, 2025 Solar farms in Britain could serve as important refuges for bumblebees, according to new research led by Lancaster University with the UK Centre for Ecology and Hydrology and the University of Reading. The benefits, however, are mostly confined to the sites themselves. In field surveys, management approach was the dominant driver of bee numbers within solar farms. Sites with wildflower mar

Paris (AFP) Oct 7, 2025 Solar and wind farms generated more electricity than coal for the first time on record this year, but US and Chinese policy shifts are slowing growth, putting a global 2030 target out of reach, reports said on Tuesday. The surge in renewable use marks a milestone in efforts to turn away from fossil fuels, which are responsible for most of the greenhouse gas emissions that are driving climate

London, UK (SPX) Oct 07, 2025 Solar energy has become the world's most affordable power source, with costs in the sunniest regions now as low as Pounds 0.02 per kilowatt-hour - cheaper than electricity from coal, gas or wind, according to new research by the University of Surrey's Advanced Technology Institute (ATI). Published in Energy and Environment Materials, the study identifies solar photovoltaic (PV) systems as

Sydney, Australia (SPX) Oct 07, 2025 Australia's world-leading adoption of rooftop solar energy has a hidden challenge: millions of aging photovoltaic (PV) panels heading for landfill. Researchers at the University of South Australia (UniSA) are now charting a path to turn this waste into opportunity, showing how extending the lifespan of panels can benefit both the environment and the economy. Led by PhD student Ishika Chhil

Berlin, Germany (SPX) Sep 25, 2025 Researchers at Lund University have taken a major step toward solving one of the biggest obstacles in developing efficient solar fuels. Their work shows how inexpensive iron-based systems could be used more effectively to store solar energy as fuel, paving the way for cheaper and more sustainable alternatives to fossil fuels. Producing fuels such as green hydrogen requires catalysts that c

Ordos, China (AFP) Oct 1, 2025 An ocean of blue solar panels ripples across the ochre dunes of Inner Mongolia's Kubuqi desert, a glittering example of China's almost inconceivably mammoth energy transition. Even as other countries have put the brakes on desert solar projects for economic or technical reasons, China - the world's largest emitter of greenhouse gases - is ploughing ahead. Desert solar installations a

Los Angeles CA (SPX) Sep 30, 2025 Honda Motor Co. and Astrobotic Technology have entered a joint development agreement to investigate scalable lunar power solutions that combine Honda's regenerative fuel cell (RFC) system with Astrobotic's Vertical Solar Array Technology (VSAT) and LunaGrid service. The collaboration aims to deliver continuous and reliable power for extended lunar surface operations, particularly during the two-
