Micro TEC Manufacture: the Importance and Challenges

Abstract

Thermoelectric (TE) technology manifests great potential in solid-state cooling and power generation, especially using micro thermoelectric cooler (Micro TEC) for precise temperature control confined to small systems. It has significant advantages, unique for needs that cannot be met by any other method. However, manufacturing Micro TEC has challenges, and not just those related to TE materials. This paper targets the issues and describes the key points in Micro TEC manufacture from the industrialization point of view, presenting the fabrication difficulties of Micro TEC and emphasizing the importance of industry-university-research cooperation, which is expected to provide helpful insights and inspiration for the development of the domestic TE industry.

Realizing thermoelectric cooling and power generation in N-type PbS0.6Se0.4 via lattice plainification and interstitial doping

“…Thermoelectric (TE) materials have garnered significant attention due to their capability of converting heat into electricity directly and reversibly 1 – 6 , which has great potential to use for waste heat recovery to improve the energy utilization and sustainability. Additionally, TE cooling technology plays a crucial role in heat dissipation for electronic products, due to its high reliability and ease of miniaturization 7 – 10 . To assess the performance of TE materials, a dimensionless figure of merit ZT = S 2 σT / κ tot was used.…”
