Title: SYSTEMS AND METHODS FOR ACHIEVING A MICRO LOUVER EFFECT IN A PHOTOVOLTAIC CELL
Abstract:
Building integrated photovoltaic (BIPV) systems provide for solar panel arrays that can be aesthetically pleasing and appear seamless to an observer. Micro louvered structures can be incorporated into photovoltaic (PV) stacks, such that light entering a PV stack that is reflected off of embedded solar cells is not directed out at angles at which a typical observer would normally view the PV stack or roof on which a solar array is installed. Further, portions of the micro louvered structures can be coated with reflective, refractive, dielectric, and/or colored films such that underlying solar cells within the PV stack are obscured from the sightlines of a typical observer.
