A Flexible and Thin Graphene/Silver Nanowires/Polymer Hybrid Transparent Electrode for Optoelectronic Devices

 

 

ABSTRACT: A typical thin and fully flexible hybrid electrode was developed by integrating the encapsulation of silver
nanowires (AgNWs) network between a monolayer graphene and polymer film as a sandwich structure. Compared with the
reported flexible electrodes based on PET or PEN substrate, this unique electrode exhibits the superior optoelectronic
characteristics (sheet resistance of 8.06 Ω/□ at 88.3% light transmittance). Meanwhile, the specific up-to-bottom fabrication
process could achieve the superflat surface (RMS = 2.58 nm), superthin thickness (∼8 μm thickness), high mechanical
robustness, and lightweight. In addition, the strong corrosion resistance and stability for the hybrid electrode were proved. With
these advantages, we employ this electrode to fabricate the simple flexible organic light-emitting device (OLED) and perovskite
solar cell device (PSC), which exhibit the considerable performance (best PCE of OLED = 2.11 cd/A2; best PCE of PSC =
10.419%). All the characteristics of the unique hybrid electrode demonstrate its potential as a high-performance transparent
electrode candidate for flexible optoelectronics.
