Abstract
A luminescent sheet having two essentially parallel opposed large area surfaces separated by one or more thin edge faces, the sheet being penetrated by one or more tapered, asymmetrically disposed cavities extending from one such surface at least partially through such sheet toward the opposite surface and a corresponding number of photovoltaic cells positioned on such opposite surface in respective concentric alignment with such cavities so that light internally reflected from the convergent side walls of such cavities toward such opposite surface is concentrated onto such cells.
