碩士 === 國立臺北科技大學 === 有機高分子研究所 === 98 === 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.
