    摘要註: 本研究為探討三種市售染料D131、D149及N3依不同比例混合後在染料敏化太陽能電池的效率表現。藉由混合實驗設計法,將D131染料、D149染料和N3染料三種染料以一定組成混合並浸入TiO2薄膜電極和組裝元件,透過電腦進行回歸作等高線圖表示,由等高線圖可以清楚看出染料之間的加成/抵消效應。由光物理特性、電池元件的效率及光電子的動力學參數來探討染料敏化太陽能電池的共敏化效應,最佳效率表現為D149:N3=1:1混合,根據電化學交流阻抗分析的計算結果顯示,這樣的混合比例確實有助於電子傳遞至二氧化鈦導帶,使電池元件效率提升。 A systematic analysis for mixed dyes of D131, D149, and N3 ternary components on performance of dye-sensitized solar cells (DSSCs) has been performed. Using an experimental design of mixture, empirical models are fitted and plotted as contour diagrams, which facilitate revealing the synergistic/antagonistic effects between these mixed dyes. Dye co-sensitization effects in DSSCs are investigated by examining the photo-physic properties, efficiency of the DSSC devices, and kinetic parameters of photo-electron transfer. The performance of DSSCs is significantly affected by the composition of dyes. The optimal performance of these mixed-dye DSSCs exists at the compositional ratio of 1/2 D149 to 1/2 N3. This composition appears to help conveying the charge transfer from the excited dye molecules to the conduction band of TiO2, leading to a higher efficiency of the assembled devices. Supplementary studies of the electrochemical impedance are in support of enhancing charge transfer of TiO2 (e-) with this co-sensitized dye. Computation on this mixed compound also indicates larger charge transfer efficiency at the electronically excited state.
