Abstract
The utility model relates to the printing technical field of a solar battery, and particularly relates to a front-side electrode structure of the solar battery, which comprises a main grid line and a fine grid line, the same fine grid line is of a gradually-changed structure on the width, and the width of the same fine grid line is gradually changed from 40 micrometers to 90 micrometers. Due to the adoption of the front side electrode structure, not only can the sunshield area be reduced, but also the serial-connection resistance of the battery can be reduced, and the transformation efficiency of the battery can be improved.
Description
Technical field
The utility model relates to the solar cell printing technology, is specifically related to a kind of front electrode of solar battery structure.
Background technology
Along with the continuous progress of photovoltaic industry, have higher requirement to the photovoltaic product in market, not only wants the continuous lifting of guaranteed efficiency, and battery sheet electrical parameter is had higher requirement.Screen printing technique is the method that the electrode of present main flow is made, the grid line that obtains by the method is meticulous and production cost is low, but occur empty seal and the high problem of shading area in the front electrode of solar battery printing process easily, the series resistance height influences battery efficiency.Prior art also has the half tone design of adopting increase grid number of lines to carry out the electrode printing to reduce series resistance, still can cause battery front side grid line shading area big, can influence battery efficiency equally.How not only to reduce the shading area but also reduce series resistance, be the problem that presses for solution in the present solar cell printing process.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of front electrode of solar battery structure at the defective of above-mentioned existence, the same thin grid line of this electrode structure is grading structure on width, can either reduce the shading area, can reduce the series resistance of battery again, improve battery conversion efficiency.
A kind of front electrode of solar battery structure technology scheme of the present utility model is, comprises main grid line and thin grid line, and described same thin grid line is grading structure on width.
The gradual change between 40 μ m-90 μ m of the width of described same thin grid line.
Described thin grid line with main grid line intersection be Breadth Maximum, thin grid line width is inversely proportional to the distance of thin grid line apart from the main grid line, is grading structure.
The beneficial effects of the utility model are: a kind of front electrode of solar battery structure, comprise main grid line and thin grid line, same thin grid line is grading structure on width, described thin grid line with main grid line intersection be Breadth Maximum, so just can guarantee that the electric current that thin grid line collects can in time and efficiently derive by the main grid line, reduce the series resistance of battery; Thin grid line width is inversely proportional to the distance of thin grid line apart from the main grid line, narrower apart from the thin grid line width that the main grid line is distant, reduced the shading area of grid line to battery sheet surface, guaranteed that more rays enters the battery sheet, convert electric energy to, improved conversion efficiency of solar cell.
This front electrode of solar battery structure can either reduce the shading area, can reduce the series resistance of battery again, improves conversion efficiency of solar cell, is suitable for commercial Application and promotes.
