Abstract

A solar cell comprises an optically transparent handle, wherein the handle includes grooves into which tabs are inserted, enabling the use of high aspect ratio tabs with minimal shading of the front side of the solar cell. Electrical connection of the tabs to busbars on the surface of the layers of the solar cell is through apertures at the bottom of each groove on the handle—the grooves being aligned to the busbars. The apertures may be filled with solder, metal pins, metal spheres, etc, and in embodiments the tabs may be metal wires. The solar cells with optically transparent handles may be formed into solar cell modules. Furthermore, in embodiments the handle with integral tabs simplifies and reduces the cost of solar cell and module fabrication since the top surface of the transparent handle including tabs may be completely flat.
