摘　　要：热电发电技术在特种电源、绿色能源、环境能量收集与工业余热发电等领域具有重要的应用价值。近年来,热电材料zT值的纪录不断被刷新,为热电器件应用技术的发展奠定了坚实的基础。然而,目前热电应用技术远滞后于热电材料科学的发展,特别是热电发电技术的大规模应用仍面临着技术瓶颈和挑战。本文介绍了热电器件设计与集成的基本原理及其关键科学与技术问题,着重总结了器件集成中的界面结构设计与优化、电极连接与器件一体化制备技术、器件服役性能与寿命评价等方面的最新研究进展。同时,分析和展望了热电发电技术规模化应用面临的挑战与发展策略。Thermoelectric (TE) power generation technology is highly expected for various applications such as special power supply, green energy, energy harvesting from the environment and harvesting of industrial waste heat. Over the past years, the record of zT values of TE materials has been continuously updated, which would bode well for widespread practical applications of TE technology. However, the TE device as the core technolo-gy for the TE application lags behind the development of TE materials. Especially, the large-scale application of TE power generation technology is facing bottlenecks and new challenges. This review presents an overview of the recent progress on TE device design and integration with particular attentions on device optimization design, electrode fabrication, interface engineering, and service behavior. The future challenges and development strate-gies for large-scale application of thermoelectric power generation are also discussed.
