NOVELTY - The device has a flat array of wide angle solar micro-concentrators e.g. trough-type collector concentrators, mounted on and optically coupled with a waveguide layer. A flat photovoltaic panel and the flat array are optically connected such that the light concentrated by the solar concentrators is directed onto the panel to produce electricity. The flat array is mounted on top of the photovoltaic panel. The waveguide layer comprises a set of mirror surfaces which redirects the light exiting the concentrators in the plane of the waveguide layer.    USE - Linked flat solar concentrator and photovoltaic device for direct placement on top of solar cells in flat panel photovoltaic systems and for collecting and guiding insolate radiation to solar cells for energy conversion.    ADVANTAGE - The concentrators deliver the normal sunlight intensity to standard silicon solar cells for multiple times, thus decreasing the number of cells required in a typical solar module. The concentrator collects light from a relatively wide angle of incidence, thus eliminating the need for active tracking. The device conserves energy without the use of imaging devices, and increases the performance of the photovoltaic cells and panels. The device enables the light incident on the photovoltaic cells to be increased, thus reducing the photovoltaic cell area needed for a particular level of power generation without requiring a tracking mechanism to maintain the cells oriented to the sun. The concentrators provide more efficient use of photovoltaic materials without the complexity of producing hybrid cells. The solar concentrators are used as a thin optical layer, thus replacing the glass layer in standard flat solar panel designs.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following:    (1) a method for making a flat solar concentrator    (2) a method for reducing a photovoltaic panel area required in a photovoltaic power system of a specified electrical power generation capacity.    DESCRIPTION OF DRAWING(S) - The drawing shows a plan view of a planar waveguide circuit unit on a layer for concentration of light with a one-to-one area correspondence between micro-concentrator output apertures and output pixels.
