Abstract: A novel, high-efficiency, extremely light-weight, inflatable refractive solar concentrator for space power is described. It consists of a flexible Fresnel lens, flexible sides, and a back surface, together enclosing a volume of space which can be filled with low pressure gas to deploy the concentrator on orbit. The back surface supports the energy receiver/converter located in the focal region of the Fresnel lens. The back surface can also serve as the waste heat radiator. Prior to deployment, the deflated flexible lens and sides are folded against the back surface to form a flat, low-volume package for efficient launch into space. The inflatable concentrator can be configured to provide either a line focus or a point focus of sunlight. The new inflatable concentrator approach will provide significant advantages over the prior art in two different space power areas: photovoltaic concentrator arrays and high-temperature solar thermal conversion systems.

Abstract: A novel, high-efficiency, extremely light-weight, robust stretched Fresnel lens solar concentrator for space power is described. It consists of a flexible Fresnel lens attached to end supports, wherein said end supports stretch the lens to maintain its proper position and shape on orbit in space. One embodiment of the new concentrator includes means for lens deployment on orbit in space. In this embodiment, prior to deployment, the flexible lens and end supports are folded into a flat, low-volume package for efficient launch into space. Another embodiment of the new concentrator includes non-deployable means of stretching the lens to maintain its proper position and shape in space. Both embodiments of the new concentrator approach will provide significant advantages over the prior art in space photovoltaic concentrator arrays. Photovoltaic concentrator arrays using the new stretched lens will be much lighter and more economical than prior space concentrator arrays.

The color-mixing lens includes: (1) a light-transmissive substrate that receives broad spectrum light from a source, (2) a first plurality of prisms, located on the substrate, that refract and chromatically disperse the light received therein toward a first plurality of locations on an active region of a target cell, and (3) a second plurality of prisms located on the substrate that refract and chromatically disperse the light received therein toward a second plurality of locations on the active region. Relative dimensions of the first and second pluralities of prisms are preselected to cause the chromatically-dispersed light to mix and thereby increase a power output of the target cell by reducing inter-junction currents therein.
