Right here we exhibit low-cost polycrystalline antimonides for far more productive thermoelectric waste-heat recovery within just 600 K than typical tellurides. This can be enabled by a design of Ni/Fe/Mg3SbBi and Ni/Sb/CdSb contacts for both a avoidance of chemical diffusion as well as a lower interfacial resistivity, noticing a report https://wasteheatrecovery13344.shoutmyblog.com/30364781/a-review-of-waste-heat-recovery
