| dc.description.abstract | 染料敏化太陽能電池(DSSCs)是最被廣泛研究的第三代太陽能電池之一，此類型電池光電流的來源-染料，是影響電池光電轉換效率與元件長時間穩定性的重要關鍵，而增加染料的吸光能力一直是染料的主要研究方向。本論文藉由分子結構設計，來調控染料HOMO與LUMO能階位置使能隙變小，最大吸收波長紅位移，而設計及合成出一個新結構輔助配位基Ligand-20和另一個新結構固著配位基Ligand-22。再使用所合成之配位基利用“One-Pot”合成法製備非對稱型釕金屬錯合物 CYC-B20、CYC-B22 。這兩個染料分子的最大吸收波長與吸收係數分別為 556 nm、21700 M-1cm-1 和569 nm、33300 M-1cm-1。最後以CYC-B20及CYC-B22當光敏化劑所組裝成的染料敏化太陽能電池元件，在AM1.5光源照射，光電轉換效率分別為8.76 %與8.89 % (於同條件下由SJW-E1所敏化的電池元件效率為7.33 %），顯示此二染料應用在DSSC的潛能。

| dc.description.abstract | Dye sensitized solar cell (DSSC) is one of the 3rd generation solar cells has been investigated extensively in the past three decades. Photosensitizer, the source for the photon to electricity conversion is the most critical component in determining the efficiency and long-term stability of DSSCs. There are lots of work is focus on enhancing the light-harvest capacity of the dye molecules. Tuning the energy level of highest occupied molecular orbital and lowest unoccupied molecular orbital to shift the ?max and energy gap of dye in a common strategy. The objective of this thesis is to design and synthesize a novel ancillary ligand (called ligand-20) and an anchoring ligand (called ligand-22) for Ru-based photo-Sensitizer. The corresponding ruthenium complexes CYC-B20 and CYC-B22 were synthized with a typical “one-pot” process. The λmax and absorption coefficient of CYC-B20 and CYC-B22 are 556 nm, 21600 M-1cm-1 and 569 nm, 33300 M-1cm-1, respectively. The conversion efficiency of the dye sensitized solar cells based on CYC-B20 and CYC-B22 dyes are 8.76 % and 8.89 %, respectively under the AM 1.5 simulated sunlight (100 mWcm-2) illumination. The efficiency for SJW-E1 dye is 7.33 % under the same cell fabrication and photovoltaic performance measureing conditions. The results reveal that these dyes display great potential for appling in dye-sensitized solar cells.
