WebMay 1, 2024 · Recently, Cakiroglu et al. investigated InSb TPV cells with an unintentionally doped 2.5-μm-thick n-type InSb absorption layer grown by molecular beam epitaxy (MBE) [26]. With a bandgap of 0.23 eV at 77 K and under illumination from a thermal emitter at 1248 K, Voc was only 83 mV with ηv of 36% and FF was 64% with a P out of 2 mW/cm 2. WebDec 15, 2004 · The lattice matched InAsSb stop etch exhibits resiliency to the substrate removal and wafer bonding processes. Substantial improvement in carrier lifetime on test structures with P‐type AlGaAsSb layers indicated incorporation of these layers into the TPV cell structure should provide significant improvement in open‐circuit voltage.
