Abstract: The present disclosure relates to a device for concentrating light onto a photovoltaic target. In one embodiment, the device may include a transparent concentrating lens having an outside surface and a top and bottom portion wherein the bottom portion may be configured to receive concentrated light. A photovoltaic strip including a conducting strip are then provided along with film adhered to at least a portion of the outside surface of the concentrating lens wherein the film engages the lens and positions the photovoltaic strip at the lens bottom portion. A dielectric fluid may then be located between the lens and the film.

Abstract: This invention describes a non-imaging, non-tracking, integrally-formed solar radiation concentrator that passively concentrates both diffuse and direct solar radiation onto photovoltaic cells to produce electricity, incorporating its features into a shingle-like element useful as a roofing material and in other structural applications. The substantially transparent, solar concentrating elements of the invention may also incorporate a system to remove waste energy in the form of heat that is not utilized in the generation of electricity. The invention further provides a thermal energy recovery system including a forced convection air system for removing waste heat from the concentrating shingle assembly and using it, if desired, for building space heat or domestic water heating.
