hana
Hoʻoulu ʻia ka TIG-BiTe-P/N-2 thermoelectric ingot me ka huila o Bi, Sb, Te, Se, doping kūikawā a me kā mākou mau hana crystallizing kūikawā.ʻO ka Bi2Te3-based thermoelectric ingot ua ulu kūikawā a hoʻopaʻa ʻia no ka hana ʻana i nā modula thermoelectric i hoʻohana ʻia no ka hoʻololi ʻana i ke kumu wela mai 100 ℃(373K) a i 350 ℃(623K) i uila.ʻO ka maʻamau, ʻoi aku ka nui o ka helu awelika o ka ZT o kā mākou p-type a me n-type ingots ma luna o ka pae wela 300K a 600K ʻoi aku ka nui ma mua o 0.7.ʻO ka module i hanaʻia me ia mau mea hiki ke hoʻokō i ka 5% pono me ka 250 ℃ Delta T. I kēia manawa, hōʻikeʻia kā mākou ingot me ka ikaika mechanical maikaʻi a me ka waiwai paʻa loa, e hāʻawi ana i ka pōhaku kī no ka hanaʻana i nā modula hana mana kiʻekiʻe.
