A solar thermophotovoltaic system has a heat exchanger containing a heat exchange fluid, and a thin-film integrated spectrally-selective plasmonic absorber emitter (ISSAE) in direct contact with an outer surface of the heat exchanger, the ISSAE including an ultra-thin non-shiny metal layer that is strongly absorbing in a solar spectral range and strongly reflective in an infrared spectral range. The metal layer has an inner surface in direct contact with an outer surface of the heat exchanger. A photovoltaic cell support structure with an inner surface in a concentric configuration partially surrounds the ISSAE; and an airgap separates the support structure and the outer surface of the metal layer. Photovoltaic cells are arranged on a portion of the inner surface of the support structure to receive emissions from the ISSAE, and a solar energy collector/concentrator allows solar radiation to impinge a portion of the metal layer.
