This Spotlight provides an overview of the use of holographic optical elements in a variety of solar-energy-conversion applications, such as holographic planar concentrators (HPCs), ultra-light trapping filters for thin-film PV cells, and a variety of spectrum-splitting filters for high-efficiency PV and hybrid energy-conversion systems. In addition to describing the applications, an overview of important hologram design, materials, and fabrication methods relevant to solar conversion are discussed.
