Phthalocyanines(Pc)，具有很好的光及化學穩定性，並且能吸收近紅外光及紅光波段的太陽光，常被使用來染料敏化太陽能電池之染料。我們研究三個新的TT1 衍生物，做為染料敏化太陽能電池之染料，分別為TN1、TQ1、35T。並分別用核磁共振光譜儀(NMR)、質譜儀鑑定化合物之結構；由紫外/可見光光譜儀及循環電位儀了解化合物的HOMO、LUMO 及吸收光譜；低能量表面功函數量測儀(AC-2)得知化合物在固態時的能階；理論計算模擬化合物在在激發態時，電子躍遷的情形；更進一步將染料製作染料敏化太陽能電池(dye - sensitized solar cells，DSSCs)探討其光電轉換效率。TT1、TN1、TQ1、35T 在AM 1.5 太陽光(100 mW/cm2)照射下，其光電轉換效率為0.88 %、0.99 %、0.14%、及0.44%。
原件的製程也會影響效率的高低，利用改變二氧化鈦的膜厚、染料溶液濃度、及染料溶液浸泡時間，可以將原本TT1 效率0.88% 增加到1.68%，若將此條件套用到其他染料，相信其它染料光電轉換效率也會有所提升。

Phthalocyanines are attractive sensitizers for DSSCs because of their intense red absorbance and excellent photochemical and electrochemical stability. Three
new TT1 derivatives, TN1, TQ1, and 35T, were synthesized and characterized by 1H NMR and mass spectrometry. Their HOMO and LUMO energy level in solution and in solid state were estimated by differential pulse voltametry,UV-vis absorption spectra and AC-2, respectively. The electron distributions of molecules in excited state were investigated by theoretical calculation. The power conversion efficiencies (ηs) of these solar cells are 0.88, 0.99, 0.14 and 0.44 % for TT1, TN1, TQ1, and 35T, under standard global air mass (AM) 1.5 solar conditions. .
Fabricating solar cell devices is the crucial factor of power conversion efficiency. By changing thickness of TiO2, concentrations of DSSC dyes, and times of dyes adsorption on TiO2, we can enhance the efficiency of TT1 from 0.88% to 1.68%. We believe that If this condition is applied to other dyes, their power conversion efficiency will also be improved.
