摘要
热电材料能够直接将电能和热能进行互相转化。由它制成的温差发电器不需要使用任何传动部件,工作时无噪音、无排弃物;和太阳能、风能、水能等二次能源的应用一样,对环境没有污染,是一种性能优越,具有广泛应用前景的环境友好型材料。本文系统阐述了传统热电材料和新型热电材料的研究现状,介绍了各系列热电材料的热电性能及适用范围等,指明了其今后的发展方向。
Thermoelectric materials can be used to transfer heat energy into electric energy directly. Thermoelectric generator works with no driving parts, no noise and no waste. It is friendly to environment, just like solar energy, water power, wind energy and other reproducible energy. The current research status of traditional and advanced thermoelectric materials are briefly described in this paper. Thermoelectric properties,application areas and development tendency of various thermoelectric materials are also outlined here.
