Gold nanotechnology just made a breakthrough in solar energy ☀️
Gold supraballs capturing nearly the full spectrum of sunlight to power next-generation solar devices.
Researchers have developed “supraballs” — tiny gold spheres that absorb nearly the full solar spectrum, including near-infrared light most systems miss.
In testing, devices coated with these nanospheres nearly doubled energy absorption.
Could this be the future of high-efficiency solar-thermal power?
Harnessing the full power of the sun has long been a challenge for modern renewable energy technology. While traditional photovoltaic systems capture visible light effectively, they miss a significant portion of the solar spectrum — especially near-infrared wavelengths that carry substantial energy.
