Abstract:
1. A method of making a lens array for use in a solar photovoltaic module, the method comprising: making glass using a float process including a float glass line; and patterning the glass using a plurality of rollers disposed along the float glass line so as to form a plurality of first lenses oriented along a common axis, wherein the rollers each have profiles such that each said first lens is patterned to have at least one convex major surface when viewed in side cross section, wherein the plurality of rollers comprise top and bottom rollers, and wherein the patterning is performed such that each said first lens has two convex major surfaces when viewed in side cross section on respective opposing major surfaces thereof so that each lens has convex surfaces on opposite sides thereof, and wherein each said lens has a focal length of about 10-200 nm.
