Here we exhibit cheap polycrystalline antimonides for much more economical thermoelectric waste-heat recovery within just 600 K than common tellurides. That is enabled by a layout of Ni/Fe/Mg3SbBi and Ni/Sb/CdSb contacts for each a avoidance of chemical diffusion plus a small interfacial resistivity, knowing a file and steady module performance https://wasteheatrecovery91233.ambien-blog.com/37203582/indicators-on-waste-heat-recovery-you-should-know
