SolOptics, the solar division of Genie Lens, has created a new lens design that improves solar PV performance by 12.5 percent. The new thin-film design can be applied to any PV module, just like a sticker.
The new design is created by the company's ray tracing software that embosses microstructures onto thin polymer film. That film can then be applied to solar panels much like tinting film can be applied to a window. In testing, the microstructures in the lens improved PV efficiency by 10 to 12.5 percent.
The microstructures in the lens provide greater light absorption, an anti-reflective coating that allows more light capture, even if the light is off-center or off-angle, and lengthen the path of light so that more electrons are stimulated and therefore more electricity generated.
Another great feature is that the lens can be applied to PV modules, regardless of what they're made of -- silicon, CIGS or cadmium telluride -- and to newly-manufactured or already existing units.
