In this paper, we're binding gold nanoparticles (GNPs) and reduced graphene oxide (rGO) by cystamine (Cys). The PEDOT:PSS mix GNPs/Cys/rGO as a hole transport layer of the solar cell. From the experimental result shows the PEDOT:PSS/GNPs/Cys/rGO/ITO film than ITO film have the best transmittance. It's transmittance was decreased for 1.01% at 545 nm wavelength. The sheet resistance of PEDOT:PSS/GNPs/Cys/rGO/ITO was reduce than PEDOT:PSS/ITO, when it was doped with Gold nanoparticles (GNPs) and rGO on ITO glass. The former is than the latter decreased for 1%. For these reasons due to impact by surface doping of composite plasmonic material.
