The basic premise has been proposed before: a display screen is stacked over one or more solar cells, which are charged by the light passing through the display. But earlier designs allowed a relatively small amount of light to reach the solar cells, resulting in very little power being generated even under the best light conditions, Motorola researchers said in the patent. The ultimate goal is to develop a device that could remain charged indefinitely,
