Transparent conductive film, photoelectric device and method for preparing transparent conductive film

Abstract

The invention provides a transparent conductive film, a photoelectric device and a method for preparing the transparent conductive film. The transparent conductive film includes: a target structure; asilver nanowire film layer on the surface of a target structure; a transparent conductive polymer filling layer filling voids inside the silver nanowire film layer and covering the silver nanowire film layer. The transparent conductive film has high electrical conductivity and high transmittance. The transparent conductive polymer filling layer can uniformly coats the silver nanowire film layer by subjecting the silver nanowire film layer to a hydrophilic treatment. By means of the covering of the transparent conductive polymer filling layer and a graphene film, surface roughness is reduced while high transmittance and high conductivity of the transparent conductive film are guaranteed. In addition, the transparent conductive film also has a flexible property. Bent a plurality of times, the transparent conductive film prepared on a flexible substrate has no significant change in transmittance and square resistance, and shows great potential to be applied to photoelectric devices, especially flexible photoelectric devices instead of ITO.
