“…In particular, we explore Si/SiO2/Pt structures. We show experimentally that these structures exhibit a selective emission spectrum suitable for TPV applications, comparable with state-of-the-art full metallic structures, and that they are thermally stable at temperatures up to 1100 K. These structures are well suited for TPV systems in combination with III-V semiconductors in the range Eg=0.4-0.55 eV such as InAsSbP [15,16] (Eg=0.3-0.55 eV) and InGaAsSb [17,18,19] (Eg=0.5-0.6 eV).…”

“…7 First, an efficient small bandgap PV cell is needed to convert a large spectral range of the thermal emission into electrical power. TPV cells with a bandgap at 0.68 eV (1.8 µm) for GaSb, 8 0.62 eV (2.0 µm) for InGaAs, 9 and 0.54 eV (2.3 µm) for quaternary InGaAsSb cells, 10 are especially suitable. Second, high operating temperatures are more suitable to shift the peak of the thermal emission into the spectral range of the PV cell, preferably more than 1000…”

“…We comment briefly on previous far-field TPV designs which have utilized Gallium Antimonide [46,47] as the photovoltaic cell for converting the thermal radiation into electric power [48]. Our analysis shows that the optimum cell design for near-field TPV is fundamentally different and the presence of van Hove Singularities in the material comprising the cell is critical for the spectrally selective nature of the transferred energy.…”
