Abstract
Techniques related to reclamation of energy leaking from waveguides are disclosed. One or more photovoltaic cells may receive light leaking from a waveguide at a first surface of the wave guide. The first surface may be opposite to a second surface at which an in-coupling element is located. The light leaking from the waveguide results from inefficiency in redirecting incoming light for propagation within the waveguide. The one or more photovoltaic cells may generate electric power from the light leaking from the waveguide.
