It may take a dash of color to create cheap solar energy.
At least according to Israeli start up 3GSolar, who say they have developed the world's first commercial size solar energy system that uses colored dyes to turn sunlight into electricity.
Dye sensitized solar cells are gaining momentum in the multi-billion dollar renewable energy market due to lower costs and their ability to create electricity in cloudy areas.
3GSolar says their first system will hit the market in two years years.
