  • Publication number: 20120012152
    Abstract: A solar battery cell having a hexagonal shape is divided into four at a straight line connecting between opposed apexes and a straight line connecting between middle points of opposed sides. Two of the divided cells are arranged without being turned upside down such that oblique sides thereof oppose each other; thus, a substantially rectangular-shaped unit is configured. In adjoining two units, an interconnector is routed from a front surface of one of the units to a back surface of the other unit. Thus, the two units are electrically connected to each other through the interconnector. Hence, it is unnecessary to route an interconnector from a front surface of one divided cell to a back surface of another divided cell at a portion where oblique sides of the divided cells oppose each other; therefore, it is unnecessary to secure a large clearance at the portion.

  • Patent number: 8067295
    Abstract: A double-side light receiving solar cell in a planer regular hexagon shape and having first electrodes on both surfaces are divided into four pieces by a line A-A? connecting two opposing apexes and by a line B-B? perpendicular to the line A-A? and connecting center points on two opposing sides. By matching oblique lines of two divided pieces without misalignment and with respective surfaces in an inversed state, the first electrodes on the same side of the two divided pieces align along the same single straight line. Then, the first electrodes that are on the same side are connected with a first inter connecter, thereby constructing a unit having a rectangular outline. Units thus constructed are arranged so that relevant sides match without misalignment. By handling on a unit basis as described above, it is possible to facilitate an arrangement of the cells and an electricity connection work.
