Abstract
The utility model provides a screen for printing a positive electrode of a crystalline silica solar cell, comprising a screen body. The screen body is square-shaped. The screen body is provided with a square-shaped printing zone, corresponding to a cell sheet of the positive electrode of the crystalline silica solar cell. Main grid lines and fine grid lines which are mutually vertical to each other are provided. The main grid lines are at least in the amount of one, and so are the fine grid lines. The width of the fine grid line is 55-65 [Mu]m. The screen for printing a positive electrode of a crystalline silica solar cell is advantageous in that through reasonable configuration of the shapes of a screen body and a printing zone, and reasonable configuration of linewidth and quantity of the main and fine grid lines, printing quality can be effectively improved, and conversion efficiency of a solar cell can be improved.
Description
Technical field
The utility model belongs to solar cell and makes the field, is specifically related to a kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode.
Background technology
When non-renewable energy resources such as electric power, coal, oil signal for help repeatedly, when energy problem became the bottleneck of restriction international community economic development day by day, more and more countries came into effect " sunlight program ", and the exploitation solar energy resources is sought the new power of economic development.Solar cell had obtained development fast as a core technology content of solar energy research in recent years, and the lifting demand of conversion ratio is also increasingly high to the requirement of electrode of solar battery.
Serigraphy is an important procedure of producing solar cell, and its printing quality (thickness, width, uniformity) influences the technical indicator of battery sheet, and the research and development of serigraphy are the important channels of improving conversion efficiency.The web plate of using in the silk-screen printing technique is the key factor that influences the serigraphy quality.Existing solar cell positive electrode Printing screen can not improve the solar cell transformation efficiency preferably.
The utility model content
The utility model is intended to solve at least one of technical problem that exists in the prior art.For this reason; A purpose of the utility model is to propose a kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode, and said a kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode can provide a kind of positive electrode Printing screen that can further improve the solar cell transformation efficiency.
A kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode according to the utility model comprises: comprise plate body, said plate shape is a square; The Printing Zone, said Printing Zone is corresponding with the battery sheet of crystal silicon solar energy battery positive electrode and be arranged on the said plate body and be shaped as square; Main grid line and thin grid line, said main grid line is vertical each other with said thin grid line, and said main grid line quantity is at least one, and said thin grid line quantity is at least one.。
A kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode according to the utility model; Can pass through reasonable disposition plate shape, Printing Zone shape; And the live width and the quantity of main, thin grid line, can effectively improve printing quality, thereby improve the solar cell transformation efficiency.
In addition, also have following additional technical feature according to a kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode of the utility model:
Said thin grid line is wide to be 55-65 μ m.
Thus, can on limited battery sheet, print more thin gate line electrode, more thin grid line is provided, improve the collection of electric current on the battery sheet greatly.
The utility model is through having following beneficial effect: through the live width of the thin grid line of appropriate design, the thin gate line electrode of more quantity is provided on the area of limited battery sheet, thereby improves the solar cell transformation efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Describe the embodiment of the utility model below in detail, the example of said embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Be exemplary through the embodiment that is described with reference to the drawings below, only be used to explain the utility model, and can not be interpreted as restriction the utility model.
Describe with reference to figure 1 below and describe according to a kind of a kind of embodiment that is used for the web plate of crystal silicon solar energy battery positive electrode printing of the utility model.
As shown in Figure 1, the described a kind of web plate that is used for the printing of crystal silicon solar energy battery positive electrode of the utility model comprises plate body 1, and said plate body 1 is shaped as square; Printing Zone 4, said Printing Zone 4 is corresponding with the battery sheet of crystal silicon solar energy battery positive electrode and be arranged on the said plate body 1 and be shaped as square; Main grid line 2 and thin grid line 3, said main grid line 2 is vertical each other with said thin grid line 3, and said main grid line 2 quantity are at least one, and said thin grid line 3 quantity are at least one.
Preferably, according to an embodiment of the utility model, said thin grid line 2 live widths are 55 μ m.
Alternatively, according to an embodiment of the utility model, said thin grid line 2 live widths are 60 μ m.
Alternatively, according to an embodiment of the utility model, said thin grid line 2 live widths are 65 μ m.
The utility model provides the thin gate line electrode of more quantity through the live width through the thin grid line of appropriate design on the area of limited battery sheet, thereby improves the solar cell transformation efficiency.
The above is merely the preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; Allly be familiar with this operator; The principle and the technical characterictic of utilization the utility model, various changes and the decoration done all should be covered by within the protection category that these claims define.
