ABSTRACT:
A method for manufacturing a photovoltaic (PV) enhancement film. The method includes providing an extrusion device with an embossing roller engraved to have a pattern corresponding to a set of absorption enhancement structures. The method includes feeding a web of substantially transparent material, such as an UV-stabilized blend of polycarbonate or acrylic. The method includes rolling the embossing roller against a first side of the web to form the absorption enhancement structures. The absorption enhancement structures each include a light receiving surface that directs at least a portion of light that passes through a second side of the web toward the first side back toward the second side (e.g., the structures may be configured to provide total internal reflection when applied to a PV device). The structures refract incident light to provide an average path length ratio of greater than about 1.10 in the PV device.
