Fabrication and thermoelectric conversion of thermoelectric concrete brick with buried unileg N-type CaMnO₃ thermoelectric module inside.

ABSTRACT: To investigate the effect of heat loss reduction due to thermal insulator and thermal interface resistance due to multi-layer structure in order to improve the efficiency of a thermoelectric device, a thermoelectric concrete brick was fabricated using a unileg n-type CaMnO₃ thermoelectric module inside. CaMnO₃ thermoelectric materials were synthesized by starting materials CaCO₃ and MnO₂ to produce a unileg n-type CaMnO₃ module. Thermoelectric concrete brick consisted of two types: I-layer brick (one layer of concrete thermal insulator) and III-layer brick (three layers of different concrete insulators). The occurring temperature difference, electric current and voltage on the CaMnO₃ module and thermoelectric concrete brick
