第七章 結論與建議
7.2 建議與後續研究
由於應用範圍廣泛，期能與產業界配合，本研究成果可用於食、
衣、住、行和空氣清淨、水質淨化等相關產業，甚至可結合目前熱門 的太陽能電池 產業。以所 謂的染料敏 化奈米太陽能 (Dye sensitized solar cell，DSSC)電池為例，如圖 7.1 所示，其主要結構由三部份組 成：(1)染料敏化的二氧化鈦奈米薄膜工作電極(由含氟錫氧化物 FTO 導電玻璃、奈米 TiO2半導體薄膜和染料敏化劑組成)、(2)含有 I–/I3–的 電解質、(3)對電極 (Counter Electrode)。由此可知染料敏化太陽能電 池是由二氧化鈦所製成的，因為二氧化鈦只會吸收紫外線波段的光，
無法利用可見光來發電，所以利用染料來當收光介質也就是光敏劑，
用來吸收可見光，故稱之為染料敏化太陽能電池。是故，欲提升可見 光之利用率，本研究所製備之可見光型二氧化鈦將有助染料敏化太陽 能電池之效能提升，而玻璃並非必然的 DSSC 基材，其他具撓屈性透 明材料亦可使用，如果可撓式 DSSC 可以結合其它建材基底，未來的 生活空間不僅環保、節能甚至可儲能，將可提供許多創新發展的空 間，以改善吾人的生活環境品質。
