Publication number: 20230275174Abstract: One or more techniques, alone or in combination, maximize a surface area of a receiver that converts light into another form of energy. One technique enhances collection efficiency by controlling a size, shape, and/or position of a cell relative to an expected illumination profile under various conditions. Another technique positions non-active elements (such as electrical contacts and/or interconnects) on surfaces likely to be shaded from incident light by other elements of the receiver. Another technique utilizes embodiments of interconnect structures occupying a small footprint. The receiver may be cooled by exposure to a fluid such as water or air.Type: ApplicationFiled: May 8, 2023Publication date: August 31, 2023Applicant: Maxeon Solar Pte. Ltd.Inventors: John Liptac, Paul Dentinger, Robert Lamkin, James Page, Tom Reynolds

Patent number: 10620294Abstract: A solar collector utilizes an inflated tubular film which concentrates sunlight onto a solar receiver. The film incorporates refractive elements in a pattern which focuses light in one or two dimensions to create foci in the form of lines, spots, or other shapes. The film may be replaceable. The film may include layers of material to optimize optical, structural, thermal, and durability characteristics.Type: GrantFiled: November 15, 2012Date of Patent: April 14, 2020Assignee: COOL EARTH SOLAR, INC.Inventors: Robert Lamkin, James Page, John Liptac, Gregory Meess, Paul Dentinger, Jacques Belanger

Publication number: 20120167949Abstract: Embodiments of the present invention include structures and methods for enhancing illumination uniformity from solar concentrators. Certain embodiments may use features on a reflective layer to globally correct for deviation in reflective behavior from a desired shape. Local features such as facets on a reflective layer are formed such that the resulting illumination profile represents a superposition of multiple facets. Features may be formed on a back film to correct the reflectance of the back film. In some embodiments, features may be formed on a front film to correct a profile from refraction. In some embodiments the corrections are for line concentrators. Global and local correction techniques may be used together, and may be used on front film or reflective film(s) together or separately. Global and/or local correction may also be used in combination with other approaches, such as secondary optic receiver compensation.Type: ApplicationFiled: December 28, 2011Publication date: July 5, 2012Applicant: COOLEARTH SOLARInventors: Paul Dentinger, James Page, John Liptac, Stuart Maestas
