Surface-textured conductive glass for solar cells, and preparation method and application thereof

Abstract

Disclosed are surface-textured conductive glass for solar cells, and a preparation method and application thereof. In the surface-textured conductive glass for solar cells, a transparent conductive film is coated on a glass substrate, and the upper surface of the transparent conductive film is textured with nano/micro-scopic U-shaped pits uniformly distributed. The preparation method comprises: coating the transparent conductive film by magnetron sputtering, and then absorbing nano/micro-spheres onto the surface of the transparent conductive film as a mask by using an immersion coating method, followed by increasing the thickness of the transparent conductive film in gaps among the nano/micro-spheres by magnetron sputtering, and finally removing the nano/micro-spheres by using an ultrasonic vibration method to realize the large-scale and low-cost production of the conductive glass with nano/microscopic U-shaped surface texture. The conductive glass obtained by the method above has high repeatability, proper U-shaped texture feature size, high distribution uniformity, high production efficiency and low production cost, and thus is suitable for popularization and applications.
