The invention discloses a transparent electrode material, a preparation method and application thereof. The transparent electrode material comprises an inner core and a tin oxide layer coating the surface of the inner core, the material of the inner core comprises Ag, and the thickness of the tin oxide layer is 1t; 1 nm. The preparation method comprises the following steps: (1) mixing and heating a silver-containing seed crystal, a first soluble silver salt, a soluble halide salt, a first solvent and a first end-capping reagent to obtain a mixed system; and (2) adding the first solution and the second solvent into the mixed system to prepare the transparent electrode material. The surface of the core material is coated with the tin oxide layer, so that the heat resistance and the conductive stability of the transparent electrode material can be improved. According to the preparation method, by controlling the concentration of added Sn < 2 + > and the water adding amount, growth of a tin oxide film is directly
