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...
The phenol-formaldehyde (PF) resin was modified by boron carbide (B 4 C). In order to investigate the modification effect of B 4 C, the residue values of pure PF resin and B 4 C modified PF resin were measured using thermal gravity. It was shown that the residue values of B 4 C modified PF resin are 71.9% and 68.4% after being pyrolyzed at 700 and 1000°C, respectively,...
