A Colorful Approach to Solar Energy (IMAGE) U.S. National Science Foundation Caption Organic solar concentrators collect and focus different colors of sunlight. Solar cells can be attached to the edges of these plates. By collecting light over their full surface and concentrating it at their edges, these devices reduce the required area of solar cells and consequently, the cost of solar power. Stacking multiple concentrators allows the optimization of solar cells at each wavelength, increasing the overall power output.
