傳統的染料敏化太陽能電池使用釕的聯吡啶錯合物作為染料，雖然有不錯的光電轉換效率，但因為價格昂貴，造成染料敏化太陽能電池成本上的一大負擔。此外，由於使用液態電解質常有溶劑揮發、滲漏的問題，也不利於發展可撓式電池。本研究則使用市售且便宜的有機染料，並透過混合兩種有機染料(雞尾酒)的方式嘗試提升效率並進一步開發膠態雞尾酒有機染料敏化太陽能電池。
本研究承接先前已完成的四個雙成份系統，選用五種有機染料D149 (D)、Mercurochrome (M)、Eosin Y (E)、Rose bengal (R)、Coumarin 343 (C)，新增三個雙成分系統D/E、 D/R 、D/C，累計共七個雙成份系統，以驗證雞尾酒有機染料提升光電轉換效率的可能性及染料單分子層填補缺陷機制的作用。實驗結果顯示M/R, M/E, D/M, D/R, D/E等雙成份系統染料在懸殊比例 (60/1, 100/1)時的電池光電轉換效率會有比具較高效率的單成分染料電池光電轉換效率還高的現象發生。
本研究亦進一步將這種具有提升效率的雞尾酒有機染料系統運用在膠態電解質染料敏化太陽能電池上。電解質方面是使用標準電解液以10% PVDF-HFP高分子膠化並摻雜10% TiO2的奈米粒子作為膠態電解質，並選用D/ M與D/R雙成份系統來探討膠態電解質與標準電解液在光電轉換效率及壽命的表現。實驗結果顯示，膠態電解質電池的效率和液態電解質電池的效率一樣高，壽命則更長。除了光電轉換效率的測定，本研究亦進行暗電流（dark current）分析，再次驗證染料單分子層填補缺陷機制的作用。

Although classical dye-sensitized solar cells (DSSCs) with polypyridyl complexes of ruthenium as sensitizers may reach relatively high overall efficiencies, the high price is a big problem. Furthermore, solvent evaporation and leakage of the liquid electrolyte limit the progress in flexible DSSCs. In this study, dye cocktails of commercial and cheap organic dyes were used with the aim to improve the overall efficiency of DSSCs with liquid electrolyte. Moreover, gel-state DSSCs were also developed by using the same dye cocktails.
Following our previous study of four binary systems, five organic dyes D149 (D)、Mercurochrome (M)、Eosin Y (E)、Rose bengal (R)、Coumarin 343 (C) were used and formed three additional binary systems(D/E、 D/R 、D/C ) in this work to prove the possibility of overall efficiency enhancement by using dye cocktails approach and the defects-filling mechanism. The experimental results showed that minute amounts of dyes, which are the ones with less adsorption ability and lower efficiency, in binary systems (M/R, M/E, D/M, D/R, D/E) can enhance the overall efficiency of DSSCs.
D/M and D/R dye cocktails were futher applied in gel-state DSSCs by using 10% poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) as gelator and 10% TiO2 nanoparticles as fillers. The experimental results revealed that overall efficiency as high as that with liquid electrolyte can be realized by the gel-state DSSCs. And longer lifetime can be achieved. Finally, the defects-filling mechanism in enhancing the overall efficiency was confirmed again by conducting the dark current analyses on the gel-state DSSCs.
