Thick Transmission Phase Holograms For Photovoltaic Concentrator Applications

It is shown that thick transmission phase holograms can either be chromatically selective or non-selective depending on the design of geometrical conditions of recording and processing of holograms. Theoretically plotted curves show that by appropriate selection of recording parametes and geometry, holographic optics can be fabricated to use almost entire useful spectrum of the sun with a reasonably good efficiency.
