Methods and apparatus relating to photovoltaic semiconductor devices

Patent ·
OSTI ID:6785934
This patent describes a laminated sheet product useful in photovoltaic devices comprising: a light-transmissive lens sheet having a first side in which a matrix of a multiplicity of concentrating lenses is formed and having an opposing substantially flat second side; a substrate adhered to the second side of the lens sheet including a layer of electrically conductive material forming a first conductor; a matrix of voids forming cell sites in the substrate extending at least through the first conductor and optically below the concentrating lenses whereby radiation concentrated by a lens is directed to a cell site for a selected angle of incidence of the radiation. The invention further comprises: a photovoltaic semiconductor crystal disposed at each cell site, in electrical contact with the first conductor and optically visible through the lens sheet.
