| dc.description.abstract | 在染料敏化太陽能電池中，有機染料做為現在較環保的代表，然而現在合成有機染料分子的方法多以金屬及多步驟的方法進行合成，不過還是有研究提出新的合成捷徑，讓合成有機染料分子變得較為環保、迅速。
本研究利用新的合成方法，快速合成不同的有機染料分子，來討論分子內部的輔助電子受體(auxiliary Acceptor)之位置對其光電性質的影響及效率的表現。將得出的分子排列以改變電子予體與增加共軛的方式使其能有更好的效率表現。當中以輔助電子受體鄰近電子予體的CYL-18最佳，效率可達7.17 %，高於市售染料Z907的7.04 % | zh_TW |

Rapid preparation of organic dye by efficient synthetic method C-H arylation and cross-dehydrogenative coupling, we synthesizing four new sensitizers (CYL-14~CYL-17) were prepared and employed to fabricate DSSCs devices affords a Voc of 0.58-0.65 V, a Jsc of 4.91-8.29 mA/cm2, and a FF of 68.8-74.1 %, which correspond to an overall power conversion efficiency of 2.25-4.85 %.
Obtain the auxiliary electron acceptor adjacent to the electron donor is the best, so our synthesizing two new sensitizers (CYL-18、CYL-19) were prepared and employed to fabricate DSSCs devices affords a Voc of 0.70-0.79 V, a Jsc of 10.43-13.74 mA/cm2, and a FF of 68.29-70.86 %, which correspond to an overall power conversion efficiency of 5.14-7.17 %.
Among them, CYL-18 efficiency is up to 7.17 %, which is higher than the commercially available dye Z907 (PCE = 7.04 %). | en_US |
