本研究首先研究如何製備低溫二氧化鈦漿料，藉由加入不同分散劑和改變溶劑比例，來找到一個適合用在可撓式染料敏化太陽能電池上的漿料。除此之外，本研究最大的重點是探討不同的濺鍍氣體，在不經熱處理下，所製備不同晶相的二氧化鈦緻密層的性質。同時，我們也將其用於可撓式染料敏化太陽能電池上，探討二氧化鈦緻密層對電池的效用。
本研究的結果利用穿透式電子顯微鏡(TEM)和X光吸收近邊緣結構(XANES)光譜來分析二氧化鈦緻密層的晶體結構、X光電子能譜儀(XPS)來分析二氧化鈦緻密層的化學鍵結、紫外光-可見光光譜(UV-Visible)來分析二氧化鈦緻密層的穿透率、霍爾量測(Hall measurement)來分析二氧化鈦緻密層的電性。組裝成電池後，量測電池效率和增益行為，並藉由電化學阻抗分析(EIS)來分析電子在二氧化鈦緻密層與電解液介面的傳遞現象。最後，本研究證明二氧化鈦緻密層可以有效提升電池的效率。

First, the effects of dispersant and solvent are studied in order to find a suitable TiO2 paste which can apply on flexible dye sensitized solar cells (FDSCs). Moreover, the most important part in the study is to research the characteristics of TiO2 compact layers of different crystal structures by using different sputtering gas without any heat treatment. Meanwhile, TiO2 compact layers are used in FDSCs and the cell characteristics are studied.
The crystal structures are identified by transmission electron microscopy (TEM) and X-ray absorption near-edge structures (XANES) spectroscopy. The chemical bonding is analyzed by X-ray photoelectron spectra (XPS). The transmittance is obtained by UV-Visible spectrum. The electrical characteristics are examined by Hall measurement. Moreover, TiO2 compact layers are used in FDSCs. Cell efficiencies and rectifying behaviors are investigated. The interface of TiO2 compact layer/electrolyte for electron transport are examined by electrochemical impedance spectroscopy(EIS). Finally, we demonstrate that TiO2 compact layers can efficiently increase the performance of FDSCs.
