• TiO_2 water/ethanol sol capable of interparticle connection was prepared through a sol-gel process and used to the fabrication of organic binder-free TiO_2 paste for photo-electrode layer formation of all plastic dye-sensitized solar cells. The average particle size in TiO_2 water/ethanol sol was in the range of 27nm-80nm and the crystal phase confirmed by XRD was anatase, brookite and rutile. The viscosity of the binder sol showed the strong dependence on the water/alcohol ratio in solution. The organic binder-free TiO_2 paste including P-25 powder as the main photoelectrode was prepared by using the TiO_2 water/ethanol sol as an inorganic binder and coated on an ITO-PEN (ITO coated on Polyethylene Naphthalate) conductive electrode by a squeeze method. And the processing parameters of TiO_2 paste fabrication on the energy conversion efficiency,η, were investigated. The maximum energy conversion efficiency of an assembled plastic dye-sensitized solar cell in this work was found to be 2.58%.
