Organic solar cells are flexible, transparent and lightweight, and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon solar cells. In Energy Technology, researchers from KIT report sunglasses with colored, semitransparent solar cells applied to the lenses that supply a microprocessor and two displays with electric power. This paves the way for other applications such as the integration of organic solar cells into windows or overhead glazing.
