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 ultrathin organic photodetector devices with performance comparable to that of the state‐of‐the‐art Si‐based inorganic photodetectors.
