Preparation method for transparent silver nanowire conducting electrode

The invention discloses a preparation method for a transparent silver nanowire conducting electrode. The preparation method comprises the following steps: (1) preparing a high length-diameter ratio silver nanowire solution; (2) conducting hydrophilization on a substrate; (3) coating the prepared silver nanowire solution on the substrate, and carrying out drying to obtain a transparent silver nanowire conducting thin film on the substrate; (4) conducting adhesion treatment on the transparent silver nanowire conducting thin film and the substrate; (5) exposing the transparent silver nanowire conducting thin film treated with adhesion to ultraviolet light, so as to obtain the transparent silver nanowire conducting electrode, wherein the adhesive force between the transparent silver nanowire conducting electrode and the substrate is high. The transparent silver nanowire conducting electrode prepared according to the method is excellent in carrier collection efficiency and relatively high in light transmittance, can improve the conductibility of a front electrode of a solar battery, reduce reflectivity, and potentially improve battery efficiency and reduce production cost, and is high in mechanical and environmental stability, and suitable for large-area low-cost preparation.
