Advanced materials (Deerfield Beach, Fla.), 27(4), 669-675 (2014-12-03)
A novel solution fabrication of large-area, highly conductive graphene films by spray-coating of a hybrid ink of exfoliated graphene (EG)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) (PH1000) is demonstrated. The fabricated graphene films exhibit excellent mechanical properties, thus enabling their application as bottom electrodes in
Transparent graphene/PEDOT-PSS composite films as counter electrodes of dye-sensitized solar cells.
