Title:
SOLAR-LIGHT CONCENTRATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/114240
Kind Code:
A3
Abstract:
A photovoltaic solar-light concentration apparatus comprises a focusing layer having a plurality of focusing elements disposed adjacent to each other. A waveguide optically coupled and separated from the focusing layer has an exit surface and a plurality of deflecting elements. Each of the deflecting elements receives a band shaped solar-light beam from a corresponding focusing element. The deflecting elements are shaped and disposed so as to deflect and trap the solar-light beams inside the waveguide at an angle that insures total internal reflection. This concentrated solar-light is conveyed along a main direction perpendicular to the exit surface towards a single or multi-junction photovoltaic cell coupled to the waveguide via a secondary optical element. The multi-junction PV cell is customized to respond to the spectral light emerging from the waveguide as changed by the partial absorption through the optics that is molded of a plastic resin.
