染料敏化太陽能電池由於製作過程簡易及便宜，目前為新一代太陽能電池研究的熱門課題。在染料敏化太陽能電池中，光敏染料是否可鍵聯並將電子有效傳至二氧化鈦為影響其效率之重要因素之一。本研究首先設計並合成一個具新型的電子予體 (donor) 的染料CS106。利用常被使用之Carbazol為主要結構，再將噻吩 (thiophene) 導入形成新的電子予體，希望藉此強化其共振體及送電子之能力。本研究分別製備電子予體(Donor) 與電子受體(acceptor) 之中間物，再將其耦合反應獲得產物CS106，以提供效率量測。 同時，為改良鍵聯到二氧化鈦的能力，本研究亦設計具另一新型電子受體含硫醯基結構 (–SO2–) 之染料CS101與CS106做比較及判斷各自之優缺點，以做為提升染敏電池之效率之參考。;Dye-sensitized solar cell is showing advantage on its simple fabrication process and low cost and is currently a popular topic for the research of new-generation solar cells. One of the important factors for the efficiency is the dyes can be anchoring and transferred electron to TiO2 for dye-sensitized solar cells. In this study, we designed and synthesized a specific novel electron donor dye, CS106. Carbazol is the main structure that is often used, and thiophene is introduced to form a new electron precursor, and expect to strengthen its ability of resonate and donor. In this study, an intermediate of an electron precursor and an electron acceptor was separately prepared, and then coupled to obtain the product CS106 to provide an efficiency measurement. In order to improve the ability of the bond to titanium dioxide, this study also designed a dye with another novel electron acceptor with sulfonyl group (–SO2–), CS101, for future comparison purposes, and wish improve the efficiency of the dye-sensitized battery.
