摘要： A light-to-electrical energy conversion device comprising a nanostructure is formed on a surface of a semiconductor substrate. The nanostructure comprises an array of basic light antenna nanocells, with the individual antenna nanocells formed as 'rectenna' structures. Light energy is absorbed within each independent antenna nanocell and converted to direct current. In one particular configuration, the structure of each basic nanocell comprises a cavity or cavities dimensioned to accept light as the wave of classical physics. These cavities function as quantum confinement sites for electrons that constitute an absorbing mass. The cavity dimensionality provides a determinative factor in wavelength discrimination of the nanocell structure.
