In this contribution, a simple method for synthesizing the TiO2 nanoporous electrodes pro-cessed at low temperature was explored. Specifically, three types of inorganic binders, i. e. ammo-nia, hydrochloric acid and deionized water, mixed with ethanol as dispersant were used to prepare the TiO2 pastes. The effects of the mass ratio between the inorganic binders and dispersant on film properties were particularly studied. Moreover, the complete all-solid-state dye-sensitized solar cells were fabricated based on prepared TiO2 electrodes. Combining the viscosity test of TiO2 paste and the micro-morphology measurement to the photoelectric characterization in time-/frequency-domain, the comprehensive analysis presents the interrelation between macroscopic photovoltaic performance and microscopic charge carrier transport mechanisms. Eventually the optimal inorganic binder and its mass ratio versus dispersant has been found out, and the maximum power conversion efficiency of the corresponding cell can reach up to 1 . 45%.
