Kachitidwe
Thermoelectric ingot ya TIG-BiTe-P/N-2 imakula ndi alloy ya Bi, Sb, Te, Se, doping yapadera komanso njira zathu zapadera zowunikira.Bi2Te3-based thermoelectric ingot imakulitsidwa mwapadera ndikukonzedwa kuti apange ma module a thermoelectric omwe amagwiritsidwa ntchito potembenuza gwero la kutentha kuyambira 100℃(373K) mpaka 350℃(623K) kukhala magetsi.Nthawi zambiri, chiwerengero cha merit ZT ya p-mtundu wathu ndi n-mtundu ingots pa kutentha osiyanasiyana 300K mpaka 600K ndi yaikulu kuposa 0.7.Module yopangidwa ndi ma ingots oterowo imatha kukwaniritsa 5% yogwira ntchito ndi 250 ℃ Delta T. Panthawiyi, ingot yathu ikuwonetsedwa ndi mphamvu zamakina abwino komanso katundu wokhazikika, kupereka mwala wofunikira kuti apange ma modules odalirika opangira mphamvu komanso odalirika.
