Characterization of a solution-processable functionalized graphene oxide (SPFGraphene oxide) was investigated by FT-IR spectroscopy and the result of elemental analysis showed that the isocyanate treatment results in the functionalization groups in SPFGraphene oxide. Doping SPFGraphene oxide to P3HT based solar cells induces absorbing spectra more strongly and a great quenching of the photoluminescence...
The authors have introduced solution-processable functionalized graphene material (SPFGraphene) in P3HT/PCBM photovoltaic devices. The best results were obtained with a P3HT/PCBM (1:1) mixture with 10wt% of graphene is open-circuit voltage (Voc) of 0.64V, a short-circuit current density (Jsc) of 5.3mA/cm2 and a FF of 0.41 which led to a power conversion efficiency of 1.4% at illumination at 100mW/cm...
