OPTICS FOR SOLAR ENERGY: Holographic planar concentrator increases solar-panel efficiency

Mike Zecchino

Dec. 1, 2008

In a holographic planar concentrator, holographic film diffracts usable frequencies of sunlight, and guides that energy toward strips of solar cells, resulting in a solar module...
