Photovoltaic (PV) enhancement films for enhancing optical path lengths and for trapping reflected light

Image Number 12 for United States Patent #7968790.

A solar energy conversion assembly for efficiently capturing solar energy by providing additional chances to absorb reflected sunlight and providing longer path lengths in the photovoltaic (PV) material. The assembly includes a PV device including a layer of PV material and a protective top covering the PV material (e.g., a planar glass cover applied with adhesive to the PV material). The assembly further includes a PV enhancement film formed of a substantially transparent material, and film is applied to at least a portion of the protective top such as with a substantially transparent adhesive. The PV enhancement film includes a plurality of absorption enhancement structures on the substrate opposite the PV device. Each absorption enhancement structure includes a light receiving surface that refracts incident light striking the PV enhancement film to provide an average path length ratio of greater than about 1.20 in the layer of PV material.
