  • Non-imaging solar concentrator and cosine factor correction device using compound polyhedral surfaces and method of use thereof
    Patent number: 9658438
    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.

  • Light concentrator structures and methods
    Patent number: 9244260
    Abstract: An arrangement utilizes diffractive, reflective and/or refractive optical elements combined to intensify and homogenize electromagnetic energy, such as natural sunlight in the terrestrial environment, for purposes such as irradiating a target area with concentrated homogenized energy. A heat activated safety mechanism is also described.
