Solar Panels in any Color

Thanks to a new technology from Switzerland, solar cells can be made ‘invisible’ to blend in the environment. White panels on white walls, red panels on red buses, grey panels on grey laptops, etc. Currently most solar cells are blue-black to maximize sun light absorption.

CSEM has developed a new technology to make white solar modules, with no visible cells and connections, a reality. It combines a solar cell technology able to convert infrared solar light into electricity and a selective scattering filter, which scatters the whole visible spectrum while transmitting infrared light. Any solar technology based on crystalline silicon can now be used to manufacture white — and colored —modules.
