Abstract The in situ electropolymerized-polyaniline (PANI) film (thickness: 5–20 μm) on FTO (fluorine tin oxide) glass doped by various counterions SO 4 2 - , ClO 4 - , BF 4 - , Cl − , p -toluenesulfonate (TsO − ), etc. was prepared with electropolymerized charge capacity of 50–600 mC cm −2 . Different doping counterions have great impact on the morphology, electrochemical activity of electropolymerized-PANI film. The electropolymerized-PANI doped by SO 4 2 - anion (PANI-SO 4 ) film with much porous morphology and pore size diameter of several micrometers possesses higher reduction current for reduction of I 3 - and a low charge-transfer resistance of 1.3 Ω cm 2 in comparison with Pt as counter electrode (CE). Dye-sensitized solar cell with PANI-SO 4 as CE was assembled, and the device under full sunlight illumination (100 mW cm −2 , AM 1.5 G) shows 5.6% photovoltaic conversion efficiency, which is comparable to 6.0% of that with Pt CE under the same experimental condition.
