The thermoelectric convertor makes use of this differential to generate an electric current .
热电变换器利用这种温差来产生电流。
The northwestern researchers note that their multiscale approach is applicable to all bulk thermoelectric materials , not just lead telluride .
西北大学的研究人员注意到，他们的多级方法适用于所有的块状热电材料，而不只是碲化铅。
The second is to choose a thermoelectric material which conducts heat badly ( so that different parts remain at different temperatures ) but electricity well .
第二是选择的热电材料的导热性差（这样不同部分就能保持不同的温度）但是导电性良好。
Widespread use of thermoelectric converters could be simpler and more efficient with organic materials because they are cheap , abundant and easily processed .
