A new graphene/silver nanowire (AgNW) hybrid transparent conductive films (TCFs) was prepared by wet-transferring a chemical vapor deposition (CVD)-grown monolayer graphene onto pristine spin coating AgNW network. It has been demostrated that concentration, diameter and spin speed of AgNW are three effective approaches to adjust sheet resistance, optical transmittance and surface mophology. The graphene/AgNW hybrid TCFs exhibited excellent optical and electrical properties as well as good surface mophology because of the uniform AgNW network coated on the substrate. We anticipate that the highly conductive transparent graphene/AgNW hybrid TCFs have huge potential in high-performance emerging optoelectronic devices such as OLEDs, LCDs, and OSCs.

Ultraviolet (UV) treatment has been demonstrated to be an effective way to removing the poly-methyl methacrylate (PMMA) residual during the process of the wet-etching transfer of graphene. The UV/Ozone irradiation with appropriate time can effectively remove the PMMA residual, resulting in a performance improvement of graphene, including the surface morphology, carrier concentration, and sheet resistance. The work function of graphene could be tuned according to treatment time without loss to the transmittance of graphene. Furthermore, we have fabricated graphene-based OPVs with a power conversion efficiency of 3.33%, which increased by 18.7% compared to the OPV without graphene modification. [ABSTRACT FROM AUTHOR]
