碩士 === 國立東華大學 === 材料科學與工程學系 === 105 === In this experiment, titanium dioxide nanoparticles were prepared by hydrothermal synthesis method. we use the screen printing method to fabricated working electrode. The scarttering layer is composed of Degussa P200-TiO2 and Degussa P25-TiO2. We find the sintering temperature of TiO2 for better performance at 500 ° C, the efficiency was 5.93%. then, investigated the influence of different layers on working electrode. We compared to hydrothermal TiO2 and Dugussa P25 TiO2, observed morphology, crystal phase and dye adsorption by FE-SEM, XRD, UV-VIS. The experiment indicate that hydrothermal synthesis method growth nanoparticles TiO2 shape uniform, no agglomeration phenomenon, crystal phase composed of Anatase and Rutile. Because of nanoparticles TiO2 existed less surface states and trap, so that used working electrode performed photovoltaic better than P25- TiO2. The experimental results of hydrothermal synthesis nanoparticles TiO2 for open circuit voltage was 0.79 V, a short-circuit current was 13.69 mA/cm2, a fill factor is 0.69, and conversion efficiency achieved 7.46 %.
