Thermophotovoltaic power conversion offers efficiencies (∼13%) higher than the currently used Si/Ge thermoelectric generators (∼6%) for Radioisotope powered space vehicles. Low bandgap GaSb TPV cells exhibit good spectral response in the 1 to 2 micron range and are hence well suited for such applications. In this work, we report on a novel idea to further enhance TPV system efficiencies by integrating the GaSb PV cell front metal contact with the TPV spectral control component, a band‐pass filter. A GaSb TPV Cell with integrated band‐pass filter contact was fabricated and its electrical and optical characteristics measured.
