    Abstract: 在染料敏化太陽能電池中,全有機染料分子扮演非常關鍵的角色,而目前染料分子的合成方式主要經由多步驟的傳統合成法。本研究提出染料分子新的合成途徑,利用推電子 (Donor) 與拉電子 (Acceptor) 末端基上質子的酸度差異,進行鈀催化之交叉脫氫耦合反應(Cross-Dehydrogenative Coupling) ,合成各式非對稱D-π-A有機染料分子,此合成法不需在反應物上進行任何官能基化步驟,並具有優異的反應選擇性與官能基容忍度,為一具有高步驟經濟效益之染料合成法。

    根據我們的合成方法,製備出三項新型的有機染料 (CYL-8, CTL-9, CYL-10),並組裝成染料敏化太陽能電池 (DSSCs) 的元件,所測得電池元件數據開路電壓為 (Voc) 0.62~0.68 V、短路電流 (Jsc) 5.51~10.10 mA/cm2、填充因子 (FF) 62.5~73.9 %、光電轉換效率 (PCE) 2.25~4.85 %。本研究提供了更快速的有機染料合成法,使得染料敏化太陽能電池的應用更具競爭力。
    ;Palladium-catalyzed cross-dehydrogenative coupling between donor and acceptor-type molecules was developed for the first time to construct organic donor-π-linker-acceptor (D-π-A) dyes in the presence of pyridine and Cu(OAc)2. The advantages of this reaction are its high reaction efficiency, high regioselectivities, excellent functional group tolerance, and synthetic simplicity from the omission of the pre-functionalization. The features of this protocol make it an ideal strategy for synthesizing D-π-A dyes of interest in dye-sensitized solar cells (DSSCs).

    Through our methodology, three new sensitizers (CYL-8, CYL-9, and CYL-10) were prepared and employed to fabricate DSSCs. The photovoltaic characterization of the devices affords a Voc of 0.62-0.68 V, a Jsc of 5.51-10.10 mA/cm2, and a FF of 62.5-73.9 %, which correspond to an overall power conversion efficiency of 2.25-4.85 %. Our aim of presenting this method was to provide practical and step-saving access to various of D-π-A-type molecules for photovoltaic applications.
