Background
Screen printing is a technique that uses the basic principle of screen-patterned partial mesh size penetration and non-patterned partial mesh size non-penetration for printing. The specific principle is as follows: the paste is poured into one end of the silk screen during printing, a certain pressure is applied to the paste part of the silk screen by a scraper, and the paste moves towards the other end of the silk screen, so that the paste is extruded onto the substrate from the mesh of the graph part by the scraper during the movement.
The production and manufacturing process of the solar cell adopts the traditional screen printing process to print the conductive silver paste on the dry cell, and the screen consists of screen yarns woven by stainless steel (tungsten steel) into different mesh sizes, PI adhesive films and photosensitive adhesives coated on the screen yarns. The screen printing plate is mainly divided into two types of screen printing plates: one type is a conventional screen, and the angle of the screen cloth is 22.5 degrees; one type is a non-netlike screen, and the angle of the screen cloth is 0 DEG and 90 deg. The basic parameters of the screen mesh mainly comprise: mesh number of mesh cloth, thickness of mesh cloth, ink permeability, aperture ratio and opening.
