Abstract: An ultra-efficient device for converting light into electricity has a dielectric medium for input light propagation, a metallic medium having an array of surface-plasmon-polariton (SPP) resonator cavities formed at nano-scale and distributed in the metallic medium below the dielectric-metal interface, each nano-scale resonator cavity having a hollow interior as a metal cathode in which a metal anode is disposed, another metallic medium electrically coupled to the anode, and another dielectric medium insulating the anode medium from the cathode medium. In each cavity, the cathode is shaped, dimensioned and spaced from the anode so that standing waves of SPP excitations generated by the input light cause quantum field emission of electrons to be rectified as an electrical output. The SPP resonator cavities may be formed in a plurality of diametral sizes corresponding to component light wavelengths to allow full spectrum energy conversion of broadband light input.
