自從 1991 年瑞士科學家 Grätzel 採用奈米結構的光電極及合適的染料，組裝成光電 效率超過 7 %的染料敏化太陽能電池（簡稱染敏電池或 DSC）後，此領域即引起學術 界的熱烈研究。染敏電池元件大致可分成五個部分：導電電極、沈積在電極上的多孔 性二氧化鈦薄膜、吸附在二氧化鈦薄膜上的染料分子、電解質和對電極，每一部份及 電池元件的光學設計或組裝都可以是一個獨立的研究題目，而染料敏化太陽能電池是否能成為商 業化產品來舒緩人類面臨的能源問題，最大關鍵還是在此類電池是否可達商業化所需 的光電轉換效率與生產成本。雖然影響染敏電池之光電轉換效率的最重要內部因素是 染料分子及二氧化鈦薄膜，但若要將染敏電池的最佳光電轉換效率展示出來及降低元件成本或是因應需要增加元件的功能（例如可撓曲或全固態），則電池元件之組裝技術 及元件的光學設計是不可或缺的一環。因此本研究計畫希望藉由集合國內在染敏電池 研究中的優秀研究團隊或具染敏電池研究所需專長且對染敏電池研究有興趣之研究者，一同努力，從染敏電池原料的設計與合成、染料自組裝在TiO2表面上的結構與行為、理論計算染料的光學性質、到電池元件的設計與組裝，一貫作業 的研究，使國內染敏電池的研究達到國際一流的水準，加速染敏電池商業化的時程。 1991 Swiss scientist Micheal Grätzel used microporous TiO2 anode combination with a ruthenium complex dye to fabricate a Dye-sensitized Solar cell (called DSC) with the photo-to-current conversion efficiency of 7 %. The field of DSC became a hot research topic. The structure of DSC can be divided into five major components: conducting electrode, thin semi-conducting oxide film deposited on the conducting electrode, dye adsorbed on the semiconducting film, electrolyte, and counter electrode. Each component as well as the devices fabrication and optical design can be a research topic itself. However, regarding to the commercialization of the DSC, the conversion efficiency and fabrication cost are the key issues. Dye and semi-conducting oxide are the key components which affect the internal conversion efficiency of the DSC. Nevertheless, only good device fabrication techniques and optical design can reveal the good efficiency of the components and reduce the fabrication cost. Furthermore, fabrication of flexible and all solid state devices for special usage also relies totally on the fabrication technique. In the proposal we combine six excellent research groups, form the design and synthesis of the key components for DSC, theortical calculation of the optical properties of the dye, the structure and kinetic study of the dye adsorbed on the semi-conductor, to the device optical design and fabrication, to work together on this DSC project. We not only want to become one of the leading research groups in the world, but also wish to push DSC into commercialization. 研究期間：10101~ 10112
