Abstract
The utility model relates to the thin grid line structure of a kind of solar battery sheet, described thin grid line and main gate line are straight line, described thin grid line and main gate line intersect vertically, the width of the thin grid line crossing with main gate line is 1.1 times to 10 times of the thin grid line width at all the other positions, and the thin grid line length crossing with main gate line is greater than main gate line width.Usefulness of the present utility model is: by adjusting the mechanism of the thin grid line be connected with main gate line, thus the stress improved because welding is formed at main gate line place, improve the disconnected grid phenomenon due to welding or generation in high and low temperature environment circulation, thus improve component aging after effect, and then improve the conversion efficiency of solar cell.
Description
Technical field
The utility model relates to area of solar cell, particularly relates to the thin grid line structure of a kind of solar battery sheet.
Background technology
Electrode of solar battery printing is a link important in manufacture of solar cells, and the transformation efficiency of its printing quality to solar cell has a great impact.The width of main gate line and thin grid line has a long way to go, in the printing process of positive electrode, due to main gate line and thin grid line junction location comparison special, easily there is empty print during printing; Even if print without void, after printing-sintering, slurry after sintering is subject to the inequality of stress herein, easily occurs breakpoint, and these factors all seriously reduce solar cell transformation efficiency, particularly in components welding process, due to welding impact, form certain stress at main grid place, the thin grid line near main grid is had a certain impact, thus obvious in component aging rear deterioration, reduce the conversion efficiency of solar cell.
Summary of the invention
The purpose of this utility model is the stress overcome because welding is formed at main grid place, for the impact of the thin grid line near main grid.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the thin grid line structure of a kind of solar battery sheet, described thin grid line and main gate line are straight line, described thin grid line and main gate line intersect vertically, the width of the thin grid line crossing with main gate line is 1.1 times to 10 times of the thin grid line width at all the other positions, be provided with chamfering between the thin grid line crossing with main gate line and the thin grid line at all the other positions, the length of the thin grid line crossing with main gate line is greater than main gate line width.
Compared with prior art, usefulness of the present utility model is: by adjusting the mechanism of the thin grid line be connected with main gate line, thus improve the stress formed in main gate line by welding, improve the disconnected grid phenomenon due to welding or generation in high and low temperature environment circulation, improve component aging after effect, and then improve the conversion efficiency of solar cell.
