Problems solved by technology

This phenomenon is closely related to the characteristics of this type of screen, because the opening rate of the grid line of this type of screen is 100%, and there is no screen in the middle of the opening. Therefore, the tension perpendicular to the grid line will cause the longitudinal tension of the screen. Deformation, resulting in the thicker printing of the grid line on the most edge

Abstract

The invention discloses an electroforming screen printing plate grid line for a solar battery. Breaking points are arranged on fine grids in the middle of the positions of two main grids of a graph. According to the electroforming screen printing plate grid line for the solar battery, the problem that the printing of the grid line at the farthest edge of electroforming screen printing plate printing is easily slightly rough; and a design of arranging the breaking points on the fine grid lines is adopted so that the condition that the printing of the grid lines at the edges is rough can be avoided, the printing quality is improved and the battery efficiency is not influenced.

Description

technical field [0001] The invention relates to an electroformed grid line for solar cells, which belongs to the field of photovoltaic applications. Background technique [0002] In order to reduce the cost of photovoltaic power generation, reducing the manufacturing cost of solar cells or improving the conversion efficiency of solar cells are two effective ways. With the continuous improvement of industrial production technology, the cost of solar cell manufacturing is decreasing, and the efficiency of solar cells is also increasing. In the case that the battery structure does not change, the printing process has a significant impact on the battery efficiency, and the optimization of the front grid line pattern can significantly improve the battery efficiency. Therefore, in recent years, the design line width of the positive grid screen has become thinner, and the line width of the conventional screen has been as small as ~45 microns. However, due to the limitation of the...
