    Abstract: 本計畫將分別針對高溫(1000k)以上工業廢熱回收開發所需的熱電模組。綜觀目前商業化熱電材料,在高溫範圍(800~1100k)並無任何可行之材料具有足夠低之成本以將熱電轉換之效益導入工業廢熱回收。因此若能在材料及製程上大幅降低成本,並能在高溫範圍使廢熱回收,實為一重要的能源課題,而本計畫所提出之解決之道便是開發新的材料製程技術以製作耐高溫且成本低之金屬氧化物,以及硫化物/氧化物複合材料,來作為P型熱電材料,再配合N型ZnO,便可製作出P型及N型交替串接的模組。本計畫研究重點包括:(1)擴散摻雜製程以得到P型及N型氧化鋅粉末;(2) 以硫化銅/氧化鋅混合來得到P型複合材料粉末; (3)燒結技術製作P型及N型塊材;(4) 氧化物熱電材料熱電優值量測; 及(5) 熱電功能性模組開發、效能量測分析及高溫廢熱回收評估。本研究計畫將深入探討氧化鋅在高溫熱電方面的應用,利用本實驗室所建立之量測平台及相關資源,整合實驗參數與結果,我們將得到適用於高溫工業廢熱回收之材料結構及模組。本計畫為期3年進行。也有先前研究所累積的基礎與經驗,相信此一研究能在期間內很有效率地做出好的結果,以期能對學術理論研究及應用更為透徹,亦同時培訓熱電相關研發人才,並對往後的產業帶來新方向。 ;The research plan will propose an efficient thermal management strategy for the industrial waste heat scavenging above high temperature (above 1000k), as well as the fabrication process and development of thermoelectric materials. This project focuses on the research and development of the low-cost metal oxide thermoelectrics, production capability, as well as device efficiency test/analysis. For contemporary commercialized thermoelectric materials, there is no viable candidate for industrial waste heat scavenging by thermoelectric conversion at large scale above high temperature range(800~1100k). If the cost of materials, fabrication process, and devices can be significantly reduced, it must be an important energy issue for industrial waste heat scavenging. The proposed solution in this project is the development and use of new materials process for the production of high-temperature metal-oxide and oxide/sulfide composite thermoelectric materials. Based on the aspect of practical applications in future industries and thermal conversion efficiency, this project has proposed highly-doped metal-oxide based thermoelectric materials, including (1) development of diffusion process to obtain aluminum-doped n-type and phosphorous-doped p-type zinc oxide powder; (2) CuS/ZnO nanocomposite for p-type thermoelectric materials; (3) the fabrication of p-type and n-type ZnO bulk by sintering technique; and (4) measurement of heavily-doped p-type and n-type ZnO thermoelectric materials and (5) thermoelectric module and the evaluation on high temperature waste heat scavenging. Our research project will demonstrate the potential applications of zinc oxide at high temperature through process innovation of ZnO. This project is aimed at the thermoelectric device suitable for industrial waste heat scavenging with the help of measurement platform built in our lab, as well as evaluation of cost and efficiency based on our experimental results. This plan will help researchers to improve its technical level and obtain potential cooperation opportunity with industries in the future, but also give trainings to thermoelectric-related researchers and engineers.
