Optimization ofp-type segmented Bi2Te3/CoSb3 thermoelectric material prepared by spark plasma sintering
Tóm tắt
A kind of p-type segmented Bi2Te3/CoSb3 thermoelectric material was prepared by spark plasma sintering (SPS). When the segmented materials were used at the temperature ranging from 300 Koto 800K, the junction temperature was optimized, which is about 500 K, and the corresponding length ratio of CoSb3 to Bi2Te3 is about 15∶2. The measured maximum power output of segmented materials is about 320 W·m−2, which is about 1.8 times as high as that of monolithic material CoSb3 under the same measuring conditions.
