Nanoantenna Arrays Seen As Possible Solar Cell Replacement
Traditional solar cells only use up to 20% of the visible light they collect, and more efficient solar cells are too expensive for mass production. Now researchers at the US Department of Energy’s Idaho Laboratory have figured out a way to capture solar energy on the cheap: plastic sheets filled with billions of nanoantennas.
