Abstract
A compound polyhedral concentrator (CPOC) lens is disclosed with one smooth curved surface facing the sun and an inner surface comprised of a 3D pattern of interpenetrating minimum deviation prisms with a common origin facing the absorber. This new type of stationary solar concentrator is used to extend the acceptance angles by minimizing blocking and tip optical losses that are common with radial Fresnel design forms. Moreover, when considering the extended time period for non-tracking of the sun's movement commensurate with the increased acceptance angles the total energy collected using a combination of a CPOC lens and a photovoltaic device will be greater than the total energy collected using the photovoltaic device by itself.
