| dc.description.abstract | 染料敏化太陽能電池為熱門再生能源元件，而釕金屬染料多是2,2’-bipyridine ligand、terpyridine ligand作為ancillary ligand，以此來進行分子修飾使效率提升，在此報導非bipyridine ligand的ancillary ligand材料合成之新穎染料。
（1）新穎的亞胺基-吡啶為基礎之釕金屬敏化劑IP102及IP104被設計、合成並應用於染料敏化太陽能電池。硫氰酸根配位基互為cis之染料IP102轉換效率(η)僅2.04%，而於ancillary ligand的imine二號位增加苯環取代基，得到硫氰酸根配位基互為trans之染料IP104，其IP系列染料EHOMO值差距達0.12 eV，並以理論計算得知電子軌域分布改變， IP104效率(η)提升至7.27%。（2）新穎亞胺基-氮雜環碳烯為ancillary ligand之釕金屬染料，被設計、合成並運用於染料敏化太陽能電池。單離出isomer染料IC101、IC102，有不同光物理、電化學特性，可知IC101混摻IC102之元件效率(η)表現僅5.5%，而IC101、IC102染料則擁有6.32%及6.59%的效率，證實單離的金屬染料製成之元件，會具有較好的效率表現。 | zh_TW |
| dc.description.abstract | Novel imino-pyridine based ruthenium sensitizers IP102 and IP104 were designed and synthesized for application in dye-sensitized solar cells. Sensitizer IP102 showed the conversion efficiency (η) of 2.04% in which one of the thiocyanate ligand was positioned trans to the imine ligand while other trans to the bipyridine ligand. The sensitizer IP104 in which the imine ancillary ligand was substituted with phenyl group, the thiocyanate ligands attached to the ruthenium metal were found positioned opposite to each other. The electronic properties of sensitizer IP104 were close to that of N719 and exhibited overall conversion efficiency of 7.27 %, which was much higher than IP102 dye. In addition, new ruthenium complexes with a novel Imino-N-heterocyclic carbene ancillary ligand were also designed and synthesized for DSSC applications. These sensitizers named IC101 and IC102 were isolated as isomers of each other and exhibited different photophysical, electrochemical properties. Systematic comparison of two isomers as well as the mixture of both was performed and the dye IC101 and IC102 exhibited 6.32% and 6.59% conversion efficiency, respectively while mixture (IC101+ IC102) showed overall efficiency of 5.51%. The results obtained indicate that the single isomer can show better performance than that of mixture of complexes. | en_US |
