| dc.description.abstract | 由於全球暖化危機，尋找好的再生能源是目前非常重要的議題，而取之不盡、用之不竭，乾淨且少污染的太陽能是目前最被看好的能源。染料敏化太陽能電池(DSSCs)是被廣泛研究的新型式太陽能電池之一。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。以釕金屬為中心的高效率錯合物染料通常是以兩個雙牙基（bipyridine）及兩個單牙基（Thiocyanate ligand﹙NCS﹚）所組成的六配位錯合物，但單牙基的NCS穩定度低。本論文研究重點即合成出一個新結構雙牙基輔助配位基Ligand-30，再使用Ligand-30取代兩個單牙基NCS利用“Two-step syntheses”合成法製備釕金屬錯合物 CYC-B30。合成CYC-B30有三種空間異構物：CYC-B30(P1)、CYC-B30(P2) 以及CYC-B30(P3)，產率分別為 4.4 ％、12.3 ％以及 6.3 ％。這三個染料分子的最大吸收波長與吸收係數分別為 526 nm (2.73×104 M-1 cm-1)、535 nm (3.69×104 M-1 cm-1)以及 534 nm (3.41×104 M-1 cm-1)。以CYC-B30(P1)、CYC-B30(P2)以及CYC-B30(P3)所敏化的電池元件，在AM 1.5 光源照射，光電轉換效率分別為 3.01 %、4.02 %以及 4.68 ％。此外，由於CYC-B30(P2)的產率最高，因此選擇以CYC-B30(P2)所敏化的電池元件與本實驗室先前所合成的CYC-B29(P2)所敏化的電池元件的光電表現做比較，以瞭解釕錯合物染料結構與其光電表現的關係。 | zh_TW |
| dc.description.abstract | Renewable energy is an important and inexhaustible subject partly due to the global warming issue. Solar energy is one of the most promising source of energy. Dye-sensitized solar cells (DSSCs) are a new generation solar cell under widely studied. Dye molecule is the source for the photocurrent of DSSC and affect the conversion efficiency and stability of the corresponding devices. Ruthenium dye for DSSC usually contains two bipyridine bidentates and two thiocyanate (NCS) monodentate ligands to form a hexacoordinated complex. However the monodentates have low stability. In this thesis we focus on the synthesis of a new bidentate ancillary ligand, named Ligand-30. Then use Ligand-30 to synthesis CYC-B30 using a “Two-step” synthesis method. CYC-B30 has three spatial isomers: CYC-B30(P1), CYC-B30(P2) and CYC-B30(P3) with a respective yield of 4.4 %, 12.3 % and 6.3 %. The max (the corresponding absorption coefficient) of these three dye molecules were 526 nm (2.73x104 M-1 cm-1), 535 nm (3.69 x 104 M-1 cm-1) and 534 nm (3.41 x 104 M-1 cm-1), respectively. DSSCs based on CYC-B30(P1), CYC-B30(P2) and CYC-B30(P3) under AM 1.5 light source achieve the conversion efficiency of 3.01 %, 4.02 % and 4.68 %, respectively CYC-B30(P2) has the highest yield among three isomers, it was used to compare with CYC-B29(P2) dye to understand the relationship between the structure and photovoltaic performance of Ru based sensitizers. | en_US |
