Surface doping of composite plasmonic material by functional graphene nanostructures for organic solar cell applications

摘要

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.
