Gold “supraballs” capture about 90% of the solar spectrum

Gold “supraballs” capture about 90% of the solar spectrum

This supraball (left) is 2,100 nanometers in diameter and is made from hundreds of tiny gold nanoparticles (right) engineered to boost solar energy absorption

At any given moment, 89,000 terawatts of solar power hits the Earth’s surface. While significant advancements have been made in harvesting this power, existing technologies do not capture the full potential of the entire solar spectrum. This limitation primarily lies in these technologies’ ability to absorb energy across the full solar spectrum.
