摘要

在本論文中，我們成功合成了一系列三苯胺衍生物染料化合物，其結構均包含推電子基團、π架橋、修飾基團及拉電子基團，本篇主要探討不同的π架橋、修飾基團及拉電子基團對其光電轉換效率的影響。π架橋採用噻吩及3,4-二氧乙基噻吩作為π共軛連接鏈。修飾基團設計以噻吩為主體的修飾基團，並加入烷基鏈增加溶解度，以利後段原件製作，並且由於烷基鏈為疏水端，可抑制染料因水氣脫落。拉電子基團採用cyanoacetic acid、rhodanine-3-acetic acid及malonic acid。
我們測量化合物其個別的吸收光譜、螢光激發光譜和電化學性質。同時也將其製作成染料敏化太陽能電池元件，利用太陽光模擬系統來進行光電轉換效率(η)的測試。

In this thesis,we have successfully synthesized a series of triphenylamine derivative dye compounds, their structures contain electron-donating groups, π bridges, modified groups and electron-accepting groups, this chapter mainly discusses the different π bridges、 modified groups and electron-accepting groups of its photoelectric conversion efficiency.π bridges with thiophene and 3,4-Ethylenedioxythiophene as a π-conjugated connection chain, modified groups design modification of thiophene as the main group, and joined the alkyl chain to increase solubility, to facilitate the production of solar cell components, and because alkyl chain has a hydrophobic nature, the introduction of hydrophobic groups can reduce the dye caused by water desorption of the case. Use cyanoacetic acid、rhodanine-3-acetic acid and malonic acid as the electron-accepting groups .
All of these compounds were characterized by UV/VIS spectrophotometer, fluorescence spectrophotometer and cyclic voltammetry.Also be made into dye-sensitized solar cell components, The power-conversion efficiency was measured by the AM1.5 simulated solar light system.
