Application in Solar Energy • With a specially designed holographic optical element (HOE), a large portion of the expensive silicon photovoltaic (PV) cells in a solar panel can be replaced • With this Holographic Planar Concentrator™ (HPC) technology, the solar modules produce more energy in all conditions when compared to a standard module with an equal area of silicon PV cells.

Application in Solar Energy

Other ways to Reduce Cost • • Materials: CIGS, Cd. Te, organics, Solar Grade Silicon Other Concentrators Solar thermal for electrical generation
