Materials scientists have recently been exploring how solar panels could be made to blend in with their surroundings by making them more transparent. If achieved, energy harvesting devices could be discreetly placed on top of windows, display screens, or even human skin ?" expanding the reach of the technology even further. By harnessing the unique properties of advanced solid materials, engineers have made progress toward transparent solar panels. But for now, even the latest designs allow less than 70% of incoming light to pass through them ?" not nearly enough for the devices to blend in with their environments.
