Solar panels have gotten thinner than a human hair. Soon they’ll be everywhere. - Vox

South Korean scientists have created solar PV cells that are 1 micrometer thick, hundreds of times thinner than most PV and half again as thin as other kinds of thin-film PV. This makes it the ideal candidate to power various things since the material will be barely noticeable and still give enough energy. We could think about integrating them into bridges, streets, or even our clothes.
