Ultra-thin metal grid-based transparent electrode and preparation method thereof

The invention discloses an ultra-thin metal grid-based transparent electrode and a preparation method thereof, and relates to the technical field of a transparent electrode. The ultra-thin metal grid-based transparent electrode comprises a surface modified flexible transparent substrate; and a conductive metal grid layer with thickness of 1-10nm is deposited on the modified surface of the flexibletransparent substrate. The preparation method of the transparent electrode comprises the steps of grafting a layer of amino group on the surface of the substrate, forming a mask plate by photoresistor adhesive printing, depositing a metal layer with thickness of 1-10nm in the gap of the mask plate, and removing the mask plate to obtain the ultra-thin metal grid-based transparent electrode. By lowering the thickness of the metal grids, the light transmittance of the metal grids is improved; and meanwhile, the metal grids still have relatively high conductivity at the thickness of 1-10nm, so that the problem of "waxing and waning" between the conductivity and the light transmittance of the transparent electrode can be solved, and balance of the conductivity and the light transmittance is realized.
