▎ 摘  要

Polyaniline (PANI)/graphene composite is a good candidate for the counter-electrode in a Pt-free DSSC. In this study, the electrochemically exfoliated graphene (EEG) from the used-battery graphite rod was produced. DC measurement reveals that EEG has a relatively low sheet resistance of 502.72 omega/square. EEG suspension in DMF was used as synthesis media of PANI/EEG composite using the direct mixing method. Raman spectra show that the PANI/EEG composite was successfully synthesized as indicated by the presence of their characteristic peaks. Current density-voltage (J-V) measurements show that the power conversion efficiency of PANI/EEG composite better than the PANI-based counter-electrode.
