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
The present invention relates to a kind of solar cell with electroforming half tone grid line, belong to the photovoltaic application field.
Background technology
In order to reduce the photovoltaic generation cost, the transformation efficiency that reduces solar cell manufacturing cost or raising solar cell is two effective ways.Along with the continuous progress of industrial production technology, the solar cell manufacturing cost is in continuous decline, and battery efficiency is also improving constantly.In the situation that battery structure does not change, typography has appreciable impact to battery efficiency, and wherein the optimization of front gate line figure can obviously promote battery efficiency.Therefore, in recent years, positive aperture plate version design live width is more and more thinner, and conventional half tone live width is little of ~ 45 microns.But because the restriction of conventional half tone silk screen string diameter, the design live width has reached the limit substantially, and thin grid line design can cause printing the raising of fraction defective again.
In recent years, the electroforming half tone begins the application at photovoltaic industry gradually.The electroforming half tone has 100% percent opening, and the grid line width design can be low to moderate＜30um, and the printing live width can be low to moderate＜50um, and the application of this type of half tone can reduce the shading-area of front metal grid line greatly, brings〉0.2% improved efficiency.
At present, the ratio that this type of half tone is used is also very little, and one of reason is the more strict control of typography needs for this kind half tone, and inappropriate printing parameter control can bring the bad generation of printing.The modal printing of this type of half tone is bad to show as two the grid line wider width in edge, the figure of design width ~ 30um, edge grid line width even can reach 500um.This phenomenon is closely-related with the feature of this type of half tone, because this type of half tone grid line percent opening 100%, does not have silk screen in the middle of the perforate, therefore, can cause that with the tension force of grid line vertical direction half tone is out of shape longitudinally, causes edge grid line printing partially thick.
Summary of the invention
Goal of the invention: be the deficiency that exists for prior art, a kind of solar cell grid line for the electroforming half tone is provided.
Technical scheme: for achieving the above object, the partially thick phenomenon of grid line edge printing has effectively been avoided in arranging of the breakpoint that the present invention passes through.
Thin grid among the present invention in the middle of two main grid positions of thin gate figure are provided with breakpoint; Described breakpoint can be on the thin grid at the edge of solar cell grid line; Perhaps, many that are begun by edge are equipped with breakpoint to all thin grid; Described breakpoint width dimensions is 20um-2mm.Begin on the thin grid of described breakpoint by the edge of solar cell grid line, the grid line number that breakpoint is set more than or equal to 1 less than or equal to the grid line total number.
The point of interruption of the present invention is positioned at the center of two main grid spacings or is in middle 1/3 regional extent of spacing.
Beneficial effect: a kind of electroforming half tone grid line design of the present invention has the following advantages:
The invention solves the edge of electroforming screen painting grid line and partially thick problem easily occurs printing, by increasing the breakpoint design at thin grid line, can avoid the edge thick situation of grid line seal to occur, improve printing quality, do not affect battery efficiency.
