| Abstract Scope |
Thermoelectric modules can covert waste and ambient heat for energy saving and IoT sensors, respectively, and also function as solid state cooling. We have recently developed Mg-Sb materials which exhibit superior properties to the long-time champion Bi2Te3 [1]. I will report on our development of module technology which is critical to translate the materials performance to modules. Effective new electrodes for the novel materials were developed, both n-type and p-type [2]. Heat exchange and other issues will also be discussed. Best practices for accurately evaluating modules will also be presented [3].[1] Joule, 5, 1196 (2021), Nature Commun. 13, 1120 (2022), Adv.
