Tanga ternary thermoelectric bismuth tellurideP ubwoko bwa Bi0.5Sb1.5Te3naN ubwoko bwa Bi2Te2.7Se0.3
Imikorere
TIG-BiTe-P / N-2 ingoteri yumuriro ikura hamwe nuruvange rwa Bi, Sb, Te, Se, doping idasanzwe hamwe nuburyo budasanzwe bwo gutegera.Ingoteri ya Bi2Te3 ishingiye kuri thermoelectric ingot ikura byumwihariko kandi igashyirwa mubikorwa kugirango ikore moderi ya termoelektrike yakoreshejwe muguhindura inkomoko yubushyuhe kuva kuri 100 ℃ (373K) kugeza kuri 350 ℃ (623K) mumashanyarazi.Mubisanzwe, impuzandengo yimpano ZT yubwoko bwa p-n nubwoko bwa n-hejuru yubushyuhe bwa 300K kugeza 600K nini kuruta 0.7.Module ikozwe ningingo nkiyi irashobora kugera kuri 5% ikora neza hamwe na 250 ℃ Delta T. Hagati aho, ingot yacu igaragaramo imbaraga zumukanishi hamwe numutungo uhamye cyane, utanga ibuye ryingenzi ryo gutanga umusaruro mwinshi kandi wizewe wamashanyarazi.
