HOW IT WORKS
The revolutionary, new Light-Capturing Ribbon increases the efficiency of a solar module by reflecting light back onto the surface of the cell. This grooved ribbon replaces the traditional wires used to interconnect solar cells.

Just as with standard interconnect wires, the Light-Capturing Ribbon is soldered to the silver busbar on top of the silicon cell and to the solder pads on the back of the next cell.

The grooved surface of the Ribbon steers incoming light back to the glass/air interface at a grazing angle that allows the light to undergo virtually total internal reflection, directing it back to the cell surface.
Up to 80% of the photocurrent from light that strikes the ribbon is recovered—far better than the 5% recovered by a standard interconnect wire.
