摘要:

熱電轉換器件作為能實現(xiàn)電能與熱能直接相互轉換的功能器件，在工業(yè)廢熱回收利用、深空深海電源、半導體制冷、雙向精確控溫等領域具有重要應用。綜述了6類熱電轉換器件的拓撲結構設計、連接界面控制、集成制造和熱電轉換性能提升策略等方面的研究進展，內容包含基于塊體熱電材料的低溫、中溫和高溫單級熱電轉換器件以及低-中溫級聯(lián)熱電轉換器件，基于熱電磁能源轉換材料的熱電磁全固態(tài)制冷器件，以及基于人造傾斜結構復合材料的橫向熱電轉換器件。同時，簡要評述了熱電轉換器件研究目前面臨的諸多挑戰(zhàn)，如熱電發(fā)電應用存在異質界面失穩(wěn)、熱電制冷應用存在材料加工和器件集成困難等。

Abstract:

Thermoelectric (TE) conversion devices, as a kind of functional devices that can realize direct inter-conversion between electricity and thermal energy, have important applications in the field of industrial waste-heat recovery, deep-space and deep-sea power supply, semiconducting cooling, and high-precision bi-directional temperature control. This paper comprehensively reviews the recent research progress of six kinds of TE conversion devices in topological structure design, interfacial connection control, integrated manufacturing, and performance optimization strategies. These devices include low-temperature, moderate-temperature, high-temperature single-stage TE conversion devices, and low-to-moderate temperature segmented TE conversion devices based on the bulk TE materials; thermo-electro-magnetic all-solid-state cooling devices based on the thermo-electro-magnetic materials; transverse TE conversion devices based on artificially tilted multilayer composites. In addition, the paper still briefly comments some of the challenges facing TE conversion devices, which refers to the heterogeneous interfacial instability for power generation applications and the issues in materials processing and device assembling for cooling applications.
