Figure 2: Current density vs. voltage characteristics of graphene OPV devices with PEDOT:PSS and MoO3 hole transporting layers with varying MoO3 HTL thicknesses (20-40 nm) under simulated AM 1.5G illumination at 100 mW/cm2. By utilizing the thermally evaporated MoO3 HTL, the wetting of HTL on graphene surface can be improved compared to the conventional PEDOT:PSS HTL.
