Over the years there are has been several attempts at creating Solar Sunglasses. But the look has been bulky and not really usable. Today, researchers from the Karlsruhe Institute of Technology (KIT) have created ‘sunglasses with colored, semitransparent solar cells applied onto their lenses that supply a microprocessor and two displays with electric power. This paves the way for future applications, such as the integration of organic solar cells into windows or overhead glazing.’
The Solar Suns will work in and outdoors and can generate 200 milliwatts of power.
