碩士 === 國立暨南國際大學 === 應用化學系 === 104 === This thesis is focuse on the optimizing dye-sensitized solar cells of two series of novel photosensitizers. The first series of dyes (Me2N-PS1, Me2N-PS2, Me2N-PS3, Oct2N-PS1) are based on the published porphyrin dyes (LD14, LD16). For these PS dyes, we introduce thiophene derivative to substitute phenylethynyl (PE) as the bridge between the porphyrin core and the anchoring group. The result show a trend of Me2N-PS1 (6.76%) > Oct2N-PS1 (6.68%) > Me2N-PS2 (6.37%) > Me2N-PS3 (4.62%) This is in consistent with the reported PE1~PE4 dyes. In the second part, stable artificial chlorophyll, derivatives (LS-01, LS-11) were synthesized and used as photosensitizers. Remarkably, LS dyes show vivid colors (pink and blue) on TiO2. Phtotvoltaic measurements show a trend of efficiencies of LS dyes LS-11 (5.36%) > LS-01 (4.67%) > H2PE1 (2.06%).
