| Summary: | 碩士 === 國立成功大學 === 材料科學及工程學系碩博士班 === 98 === 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.
