SOLAR CONCENTRATION SYSTEM USING VOLUME HOLOGRAMS

摘要

An electromagnetic wave concentrating system, comprising a photovoltaic material and at least one holographic concentrator. The holographic concentrator includes at least two stacked holographic optical elements (HOE). Each HOE is configured to diffract incident light into a diffracted beams having different ranges of wavelengths. The diffracted beams generated by each HOE are directed at the photovoltaic material.

1. An electromagnetic wave concentrating system, comprising:
a photovoltaic material; and at least a first holographic concentrator, comprising:
a first holographic optical element (HOE) configured to diffract incident light into a first diffracted beam having a first range of wavelengths, and at least a second HOE configured to diffract incident light into a second diffracted beam having a second range of wavelengths, different from the first range of wavelength, the first and the second diffracted beams directed to the photovoltaic material,wherein:
the first diffracted beam is at least partially incident on and transmitted by the at least second HOE.
