Over the last decade, different techniques had been employed to prepare nanoporous TiO₂ electrode, aiming to improve the electron transport and depress electron recombination processes in dye-sensitized solar cells (DSCs). An effective method was a post-treatment of the TiO₂ films in which an extra layer of TiO₂ was grown onto the TiO₂ nanoparticles constituting the films. Different explanations of the working principle of this coating had been reported. In the present work, the influence of surface modification of TiO₂films on microcosmic performances of DSCs was investigated. Research was developed by the post-treatment of TiO₂ films using electrodeposition method. Ti⁴⁺ oxide films were deposited on TiO₂ electrode by anodic oxidative hydrolysis of acidic aqueous TiCl₃ solutions. The pH was adjusted to 2.2 and the rate of oxidation of Ti³⁺at the anode was controlled by an almost constant anodic current using constant potential rectifier. The processes of electron recombination, transport and band edge movement were detected by intensity-modulated photocurrent spectroscopy (IMPS)/intensity-modulated photovoltage spectroscopy (IMVS) and electrochemical impedance spectroscopy (EIS). It was found that the capacitance of TiO₂ electrode evidently increased with increasing electrodeposition time at high potentials due to the risen density of shallow traps. As the formation of small particles on the surface of TiO₂ films and the enhancement of particle connections, the post-treatment with different electrodeposition time improved the charge injection and transport processes and depressed the electron recombination effectively. IMPS/IMVS measurements indicated that the effects of surface modification almost relied on light intensities, which would perform more prominent function at low intensities. Additionally, the open-circuit photovoltage (V_oc) was found to be mainly effected by the conduction band edge shift and the variation of charge recombination process. With increasing electrodeposition time, the conduction band was ordinally positive shift due to the increase of surface charge, which contributed an improvement of short-circuit current (J_sc) but a limitation of V_oc. Overall, an optimal modification time was needed to achieve a higher J_sc and V_oc.
