  • Patent number: 11177767
    Abstract: An apparatus for generating electricity from solar energy has a large dish reflector with a fly's eye receiver positioned near the focus of the dish reflector, held by a dual axis tracking structure. The fly's eye receiver includes a field lens that concentrates sunlight into an image of the dish reflector, a two-dimensional fly's eye array of contiguous convex lenses extending across the dish image, and a photovoltaic cell behind each convex lens of the fly's eye array. Two imaging stages are provided. First, the dish reflector and the field lens concentrate the sunlight in the form of an image of the dish that is stabilized against pointing errors of the tracking mechanism. Second, the contiguous array of convex lenses divides the sunlight energy of the dish image into portions, one per convex lens, each portion being further concentrated by the respective convex lens onto a corresponding photovoltaic cell.

  • Patent number: 10551089
    Abstract: A solar concentrator may have a horizontal circular track on the ground, a tower centered on a vertical axis of the track, and a rotatable structure around the track having an upper, concave mounting surface approximating the shape of part of a sphere centered on the top of the tower. Articulated concave mirrors are attached to the rotatable structure, and the mirrors have a focal length approximately equal to the radius of a sphere portion formed by the concave mounting surface. Sunlight is focused at a receiver mounted atop the tower, and the receiver may convert sunlight into thermal or electrical energy. As the position of the Sun changes, sunlight is maintained on the receiver by turning the rotatable structure toward the Sun, turning the receiver about said vertical axis to face the mirrors, and articulating the mirrors toward the receiver in response to the changing elevation of the Sun.
