The formulation and the preparation of a TiO 2 paste for dye‐sensitized solar cell technology are proposed. The TiO 2 paste is characterized in terms of rheology, morphology, cross section, specific surface area, and average pore size. A conversion efficiency of 7.42% without any chemical treatment or scattering layer was obtained using the optimal thickness of 11 µm as carried out in this work. The results over different batches of the paste confirm the stability and the reproducibility. The characterization of the TiO 2 semi‐transparent film is completed by investigating the dye adsorption saturation time after cyclic dye dipping steps through UV–Vis spectra measurements.
