This study presents a transparent conductive film (TCF) based on a graphene/Ag/graphene (G/Ag/G) sandwich structure. An enhancement in the optical transparency of Ag in the visible wavelength region was observed when the Ag layer was sandwiched between monolayer graphene sheets, attributed to plasmonic effects. The G/Ag/G composite films, with the top graphene layer p-type doped, demonstrated an optical transmittance of 90.8% at 550 nm and a sheet resistance of 130 Ω/sq. These results indicate the strong potential of G/Ag/G films for use as ultrathin, lightweight, and flexible TCFs.
