Photovoltaic Systems Based on Spectrally Selective Holographic Concentrators

摘要

The purpose of the work was to demonstrate the feasibility of a new holographictechnique for concentrating solar energy and splitting its spectrum with a single hologram to generate power, using two or more solar cells optimized at different portion of the solar spectrum. Various holographic materials, techniques for making holograms, and combinations of solar cells of different materials were investigated. Techniques were developed for testing system efficiencies. A number of potential problems and difficulties were successfully addressed. Holograms and solar cell systems were fabricated and tested, and demonstration units fabricated.
