Abstract: The present application is directed to methods of forming an integral lens sheet for use with a photovoltaic solar cell subassembly. The integral lens sheet is constructed from a parquet member and one or more individual lenses. One embodiment of a method may include positioning an individual lens over each of the apertures in the parquet member. The size of the lenses may provide for peripheral sections of the lenses to overlap the parquet member. Each of the lenses may be welded to the parquet member by directing a laser beam through the peripheral sections and onto the parquet member. The laser beam may form a laser weld between the parquet member and an underside of the individual lenses.
