Not long ago, solar cells were all huge, heavy, stiff devices. Recently that’s been changing—and the latest development is a new breed of cells which are thinner than spider silk and can even be wrapped around objects as small as a human hair.
According to research published in Nature Communications, a team of scientists from Austria and Japan has created these new, thin-film soar cells that are just 1.9 micrometers thick. That’s over ten times thinner than any other solar cells ever made, and is thinner than a thread of spider silk.
