Right here we demonstrate cheap polycrystalline antimonides for more successful thermoelectric waste-heat recovery in 600 K than regular tellurides. This is often enabled by a structure of Ni/Fe/Mg3SbBi and Ni/Sb/CdSb contacts for both a avoidance of chemical diffusion along with a low interfacial resistivity, noticing a document and secure module https://wasteheatrecovery91234.isblog.net/an-unbiased-view-of-waste-heat-recovery-48413896
