| dc.description.abstract | 染料敏化太陽能電池 (Dye Sensitized Solar Cell, 簡稱 DSC ) 因成本低廉、製造簡易、色彩多樣化及室內弱光高效率發電的特性，具有發展的潛力。實驗室合成出的染料DUY29有不錯的光伏表現，然而卻仍有兩個缺點：DUY29有高的HOMO能階，不利電解質還原染料；DUY29染料因體積大，在TiO2膜上有低的吸附量，導致元件有低的Jsc值。本研究以DUY29結構為基礎，用dithieno[3,2-b:2’,3’-d] thiophene (簡稱tThp) 取代DUY29中的 thieno-[2,3-b]thiophene (簡稱cis-fThp) 輔助配位基，降低所合成環金屬錯合物的HOMO能階，合成出HBC30；以Thiophene 取代DUY29的 cis-fThp與2,3-dihydro-thieno-[3,4-b][1,4]dioxine (簡稱EDOT)，分別合成出HBC23和HBC31，可縮小錯合物體積。HBC23、HBC30與HBC31 (簡稱HBC系列染料)和實驗室所合成之DUY28與DUY29 (簡稱DUY系列)染料的HOMO能階由高到低為：DUY29 > HBC31 > HBC23 > DUY28 > HBC30。其中HBC23雖然HOMO能階不是最低的，但有最高的染料吸附量，所敏化之元件能將光更有效的轉換成電流，因此元件有最高的光電轉換效率，達8.62%。 | zh_TW |
| dc.description.abstract | Dye sensitized solar cell (DSC) is known for its low cost, great variety of colors and high efficiency under dim-light condition. Our Lab members previously had synthesized cycloruthenated sensitizer coded DUY29, which performs good photovoltaic properties, but has two drawbacks: First, DUY29’s has high HOMO potential which is unfavorable for dye regeneration; Second, the dye-loading on TiO2 thin film is small due to its large molecular size, resulting in a low short-curcuit current density (Jsc). This work intends to develop high efficient dyes based on DUY29. We replace thieno-[2,3-b]thiophene (cis-fThp) with the dithieno[3,2-b:2’,3’-d] thiophene (tThp) on DUY29 for lowering the HOMO potential to form HBC30; replace cis-fThp with thiophene (Th) or 2,3-dihydro-thieno-[3,4-b][1,4]dioxine (EDOT) with thiophene for decreasing the molecule size to form HBC23 and HBC31, respectively. Compared with the previously prepared DUY28 and DUY29 (DUY series) dyes. The order of the HOMO potential is DUY29 > HBC31 > HBC23 > DUY28 > HBC30. Although the HOMO potential of HBC23 is not the lowest, the dye loading (on TiO2 thin film) is the highest, resulting in the highest Jsc of DSC device. As a result, the power conversion efficiency of HBC23 sensitized solar cell is the highest, reaching 8.62 %. | en_US |
