Tiny gold supraballs nearly double solar absorption, boosting efficiency for cheaper, scalable solar energy.
Tiny gold supraballs, nanoscale structures made of hundreds of gold nanoparticles, nearly double solar energy absorption compared to traditional materials, capturing up to 89% of sunlight in tests.
Designed to enhance light absorption across a broad spectrum, including near-infrared, they show promise for boosting solar-thermal and photovoltaic systems.
The coating, created under normal conditions, could enable simpler, scalable production.
Simulations predict over 90% efficiency, offering a cost-effective path to higher-performing solar energy devices.
