熱電效應是利用熱電材料本身的特性，將熱能與電能相互轉換的現象，而廢熱存在於我們身邊許多裝置，回收這些廢熱在環保層面有著非常高的價值。熱電元件的應用非常廣泛，可以做為發電系統的廢熱回收，亦可做為致冷晶片使用，或是汽車的能源回收，甚至可做為隨身裝置晶片的能源。而熱電材料為固態設備，具有無汙染、體積小、重量輕、無噪音、無耗損、結構簡單等優點。目前科學家著重於奈米結構的改良與複合材料的開發，以期能夠增加ZT值，使熱電效應能夠達到商業化應用之標準。 本研究著重於探討硫化銅-氧化鋅合金與其他材料之熱電特性，找出合適的p-type材料應用於熱電模組的製作。量測範圍於室溫至523K，並探討其熱電模組的特性與未來應如何改善熱電模組的效能。 ;The thermoelectric effect is a phenomenon of converting heat energy to electricity, and can be used in wide applications, including waste heat recycling, thermoelectric cooler, and portable power. It has the advantages of no pollution, small volume, light weight, no noise, and simple component structure, etc. This study was focused on the development as well as the thermoelectric properties of CuS-ZnO alloy and the module made by this p-type material. Thermoelectric module was measured from room temperature to 523K, and the characteristic performance is analyzed and discussed.
