Abstract: A method for producing a mosaic solar cell assembly, comprising the steps of singulating a III-V compound circular semiconductor solar cell wafer having a wafer surface area into four discrete solar cell mosaic elements each substantially shaped as a quadrant of a circle; selecting a first and second solar cell mosaic element each having one curved edge in the shape of an arc of the circumference of the circular wafer from which the element was singulated, and three straight edges; and rearranging and positioning the first and second mosaic elements into a substantially rectangular mosaic assembly.

Abstract: A method for producing a mosaic solar cell assembly, comprising the steps of singulating a III-V compound semiconductor solar cell wafer into four identical discrete solar cell mosaic elements each substantially shaped as a quadrant of a circle, comprising a first and second solar cell mosaic element having one curved edge in the shape of an arc of the circumference of the circular wafer from which the element was singulated, and a single straight edge, rearranging and positioning two of the mosaic elements into a substantially rectangular mosaic assembly; providing a metal interconnect between each of the mosaic elements along one edge of the assembly so that the mosaic elements may be electrically connected to an adjacent mosaic assembly; and optionally bonding the cover glass support to the top of the mosaic assembly.

Abstract: A space-qualified solar cell assembly comprising a plurality of space-qualified solar cells, each space-qualified solar cell of the plurality of space-qualified solar cells being shaped as a portion of a circle, the portion having at least one curved edge having a shape of the arc of the circumference of said circle and at least one straight edge, the portion having a surface area corresponding to not more than 50% of the surface area of the circle. This makes it possible to make efficient use of the material of the wafer from which the space-qualified solar cells are produced by reducing waste, while arrangement of the space-qualified solar cells into rectangular unit cells enables construction of substantially rectangular space-qualified solar cell arrays and assemblies that have their surface area covered substantially by space-qualified solar cells with little area unoccupied by space-qualified solar cells.
