| Abstract Scope |
Thermoelectric materials and devices can directly convert heat into electricity with solid-state elements, and thereby function as waste heat power generation, IoT power sources, etc. [1]. We have recently developed magnesium antimonide thermoelectric materials & devices which surpass the traditional champion bismuth telluride [2]. I will present recent developments for further Mg-Sb n- and p-type material enhancement, electrodes, fabrication of modules. Not limited to Mg-Sb, we have also been developing various formats of thermoelectric modules, i.e. bulk, flexible, thin film, to accommodate various applications. Accurate thermoelectric module evaluation is increasingly important and best practices will also be presented.
