The effects of paste components on the properties of porous TiO2 film electrodes prepared through screen-printing technique were investigated in order to e films were fabrication step of the dye-sensitized solar cells (DSSCs). The screen-printed porous TiO2 method and characterized by means of spectroscopy (XRD), microscopy (SEM) and electrochemical evaluated as part of DSSCs for the energy conversion. The experimental results indicate that the microstructural characteristics of the printed films and the performances of the corresponding DSSCs are dependent on the paste compositions. The experimental repeatability is nice and the properties of the film are uniform after the optimization of paste composition. (C) 2009 Elsevier Ltd. All rights reserved.
