dc.description.abstract | 近年來由於能源的需求被大幅提升,但同時能源枯竭以及氣候變遷的問題也越來越嚴重,因此發展可再生能源成為一個重要的議題,其中,使用熱電發電是近期被熱烈討論的一種再生能源。熱電材料可以藉由環境中的廢熱造成溫差產生電流,使電能與熱能可以直接互相轉換,此種發電方式不會產生噪音,不需要很大的空間,也不會排放碳汙染,因此是極具潛力的綠色能源。
本文研究了P型Mg2(Si,Sn)熱電材料。 我們的研究結果表明P型Mg2(Si,Sn)熱電材料的最佳製程參數是在800℃下燒結1小時,然後添加10% Mg在400℃下退火48小時。 Seebeck係數達到312μV/ K,熱電優值(ZT)的峰值為0.185。
將P型材料的最佳製程用於模組。製備了摻雜2at% Bi和10at% Mn5Si3的Mg_2 Si_0.4 Sn_0.6作為模組一的N型材料,摻雜10at% CeO2的In_2 O_3作為模組二的N型材料。兩個模組進行熱電性能的量測,最大輸出功率分別為1076.138 nW和234.95 nW。 | zh_TW |
dc.description.abstract | In this thesis, P-type Mg2(Si,Sn) thermoelectric materials is investigated. Our research results show that best process parameters for the P-type Mg2(Si,Sn) thermoelectric materials were sintering at 800℃ for 1 hour and then 400℃ for 48 hours with 10% Mg additives. The Seebeck coefficient reached 312μV/K and a peak thermoelectric figure of merit (ZT) was 0.185.
The P-type material was used for a module according to the best process. Module 1 by Mg_2 Si_0.4 Sn_0.6 doped with 2at% Bi and 10at% Mn5Si3 as N-type materials and module 2 by In_2 O_3 doped with 10at% CeO2 as the N-type material were fabricated. The thermoelectric performance was measured and the maximum output power of two modules is 1076.138 nW and 234.95 nW, respectively. | en_US |
