碩士 === 國立暨南國際大學 === 應用化學系 === 104 === In this thesis, LS-00, LS-01, LS-03 and H2N-Ph-Zn(t-Bu)-Ph-NO2 were synthesized. The LS-01 dye is used in dye-sensitized solar cell as the photosensitizer; Electropolymerized film of LS-03 is used in dye sensitized solar cell as the cathode material. For LS-01 and LS-03 sensitizers, a benzoic acid group or an aniline group were connected to the bacteriochlorin core through C-C triple bonds. For H2N-Ph-Zn(t-Bu)-Ph-NO2, an aniline group and a nitro group were coupled to the macrocycle. They were connected to the porphyrin core through C-C triple bonds. The UV-visible, fluorencene emission, electrochemical, energy level diagram and density functional theory showed that LS-01 can be used in n-type solar cells. With an I-/I3- electrolyte, the LS-01 DSSC shows a power conversion efficiency of η = 4.98%, which was higher than a reference porpyrin dye, H2PE1 (η = 2.18%). We synthesized LS-03 to prepare electropolymerized film on FTO. This polymer film can use as cathode in dye sensitized solar cell. DSSC application of LS-03 polymerized cathode and N719 as photosensitizer showed an power conversion efficiency of η = 0.57%, which was lower than Pt traditional cathode (η = 6.63%).
