Methods and apparatuses for harvesting light from displays. In one embodiment, the invention relates to a substrate having a first and a second surface, an edge and a luminescent dye. A photovoltaic transducer is positioned adjacent the substrate. Light passing through both the first and second surfaces of the substrate is polarized and light constrained within and traveling through the substrate interacts with the photovoltaic transducer to produce electric current. In one embodiment, the method of harvesting light from an illuminated electronic display including the steps of providing a light source, providing a substrate having a first and a second surface and an edge; and a luminescent dye; and providing a photovoltaic transducer positioned adjacent the substrate. Light passing through both the first and second surfaces of the substrate is polarized, and light constrained within and traveling through the substrate interacts with the photovoltaic transducer to produce electric current.
