碩士 === 國立臺北科技大學 === 化學工程研究所 === 100 === A preparation technique of TiO2 screen-printing pastes from commercially available powders (P25, P90, ST-01, ST-21) was disclosed in order to fabricate the nanocrystalline layers with different recipes of slurry which were made up of four kinds of TiO2 powder by DOE (Design of Experiment). The TiO2 film was measured the light transmission of the prepared by using haze meter, the amount of adsorption by UV/Vis spectroscopy, the bonding between N3 dye and TiO2 surface by DRIFTs (in situ Diffuse Reflectance Infrared Fourier Transform Spectroscopy), and the photoelectric conversion efficiency by IPCE (incident monochromatic photon-to-electron conversion efficiency). Results of DOE were analyzed by the Analysis of Variance (ANOVA) technique to evaluate the weighting and the correlations between the powders. Moreover, the artificial neural network (ANN) method was employed to predict the best recipe of slurry.
