Thermoelectric materials can be potentially employed in solid-state devices that harvest waste heat and convert it to electrical power, thereby improving the efficiency of fuel utilization. The spectacular increases in the efficiencies of these materials achieved over the past decade have raised expectations regarding the use of thermoelectric generators in various energy saving and energy management applications, especially at mid to high temperature (400-900 °C). However, several important issues that prevent successful thermoelectric generator commercialization remain unresolved, in good part because of the lack of a research roadmap.
热电材料有望应用于固态设备，这些设备能够收集废热并将其转化为电能，从而提高燃料利用效率。在过去十年中，这些材料的效率大幅提高，这使得人们对热电发电机在各种节能和能源管理应用中的使用寄予厚望，尤其是在中高温（400-900°C）环境下。然而，一些阻碍热电发电机成功商业化的重要问题仍未得到解决，很大程度上是因为缺乏研究路线图。
