Abstract
The invention relates to an integrated solar cell which includes a plasmonic layer which includes a pattern configured to support plasmon waves, The plasmonic layer is configured to receive as input light energy of an incident light and at least one photon of light received from one or more layers in optical communication with the plasmonic layer and to re-emit as output a guided light to the one or more layers in optical communication with the plasmonic layer. A wavelength conversion layer is configured to receive as input at least one photon having a first wavelength and to provide as output at least one photon having a second wavelength different than the first wavelength. A photovoltaic layer is optically coupled to both the wavelength conversion layer and the plasmonic layer, the photovoltaic layer configured to convert at least one photon having the second wavelength to electrical energy.
