Abstract: Embodiments provide a photovoltaic cell, including: a first conduction layer; a second conduction layer; a photonic absorption layer electrically coupled to the first conduction layer, the photonic absorption layer is tuned to absorb incident light at a first wavelength of the incident light to generate a first electric current along the first conduction layer; and a plasma-sonic layer electrically coupled to the photonic absorption layer and the second conduction layer, the plasma-sonic layer includes nanoparticles, the nanoparticles are tuned to a second wavelength of the incident light that induces electrons to oscillate at a surface of the nanoparticles.
