| Summary: | 碩士 === 國立雲林科技大學 === 化學工程與材料工程研究所 === 95 === Nano-titanium-dioxide (TiO2) porous thin film electrodes and polyalkylfluorene based electrolytes were prepared for applications in the dye-sensitized solar cell (DSSC). A sol-gel method was adopted to form titanium dioxide nanoparticle (HTP) and titanium dioxide nanotube (HTT).The HTP and HTT with the anatase phase were characterized by the XRD diffractrometer. Large specific surface area and high porosity characteristic of the HTP and HTT were evidenced by BET characterization, which were favorable for enhancing the amount of adsorbed dye molecules on the surface of titanium dioxide. Consequently, the solar energy to electricity conversion efficiency would be improved. Moreover, the alkylfluorene based mainchain type polyelectrolyte (MPF-E) and hyperbranched polyelectrolyte (HPF-E) were synthesized in this study. The photovoltaic properties of these polyelectrolytes based N719 dye-sensitized solar cells could be improved due to the increase of the ion conductivity. Higher short circuit current and greater solar energy to electricity conversion efficiency of the MPF-E and HPF-E based solar cells were observed as compared to the ones with liquid electrolyte. The conductivity effects of MPF-E and HPF-E electrolytes on the photovoltaic properties were also studied for the N719 based dye-sensitized solar cells.
