Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of transparent conductive electrodes, and in particular relates to a preparation method of silver nanowire transparent conductive electrodes. Background technique [0002] Generally speaking, a transparent conductive electrode means that the transmittance to the spectrum of the incident light wavelength range between 380nm and 780nm is greater than 80%, and the resistivity is lower than 10. -3 Ω·cm film electrode. In 1907, Badeker reported the translucent conductive CdO material for the first time. It was not until the Second World War that the transparent conductive film (Transparent conductive film, TCF) material received enough attention and application. Now, TCF materials (such as ITO (Indium tin oxide)), TFO (fluorine-doped tin oxide) have been widely used in flat panel display, energy-saving glass and solar cells. From a physical point of view, the light transmission and conductivity of materials are...
