Abstract

A solar antenna array may comprise an array of randomly placed carbon nanotube antennas that may capture and convert sunlight into electrical power. Methods for constructing the solar antenna array may use a mold and self aligning processing steps to minimize cost. Designs may be optimized for capturing a broad spectrum of non-polarized light. Alternatively, the array may generate light, and when connected in to an array of independently controllable sections may operate as either a reflective or light transmitting display.
