摘要:	摘要： Ethyl cellulose (EC)-based TiO2 pastes were prepared in order to fabricate flat and crack-free TiO2 films employing screen-printing technique. Pure anatase TiO2 was synthesised via hydrothermal process using titanium (IV) n-butoxide as Ti-precursor and peptised by acetic acid. The as-prepared TiO2sol was employed in making a series of pastes with various weight ratios of ethyl cellulose for screen-printing the TiO2 electrode for dye sensitised solar cells (DSSCs). The printed TiO2 electrodes were characterised by surface profile meter, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The printed TiO2 electrode observed under the micro-scale condition exhibited a porous and crack-free structure. After the DSSCs performance measurement, the amount of dye adsorbed on TiO2 electrodes was determined by UV-vis. The DSSCs made from paste with 5.82 wt % of EC demonstrated a high energy conversion efficiency of 7.17% with Jsc = 14.86 mA/cm2, VOC = 0.75 V and FF = 0.64 under the AM1.5 with an illumination of 100 mW/cm2. 其他題名： ijnt 出版者： Inderscience Publishers Ltd 出版日期： 2014 出處： International journal of nanotechnology., 2014, Vol.11 (12), p.1138-1147 版權： Copyright © 2014 Inderscience Enterprises Ltd. 識別號： ISSN: 1475-7435 識別號： EISSN: 1741-8151 識別號： DOI: 10.1504/IJNT.2014.065140
