MIT amps up solar cells

MIT is developing a new solar cell technology that results in a tenfold increase in power conversion, takes up less space, and can be added to existing solar panels.

Organic solar concentrators collect and focus different colors of sunlight. Solar cells can be attached to the edges of the 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.
