Abstract
The utility model discloses a solar cell light receiving face gate line which is a wavy conductive line which is attached at a silver paste layer of a light receiving surface through screen printing. The silver paste layer is also attached with strip electrode layers which are perpendicular to the conductive line. A gap between wavy conductive lines is larger than or equal to 0.3 mm, and the width of each of the strip electrode layers is less than or equal to 1 mm. According to the solar cell light receiving face gate line, under the condition of not changing the existing process and not replacing production equipment, the capacity of charge enrichment of a solar cell can be raised, and the generating efficiency of the solar cell is raised.
Description
Technical field
The utility model relates to a kind of solar battery sheet, is specifically related to a kind of solar battery sheet sensitive surface grid line.
Background technology
Solar power generation more and more is subject to people's attention due to its environmental protection and reproducible performance.The principle of solar cell power generation is based on semi-conductive photovoltaic effect, and solar radiation is converted into electric energy.Solar battery sheet in the market comprises silicon chip and is etched in main grid line on silicon chip, a grid line, its main grid line, the straight line of a grid line for intersecting, and the main grid line is thicker.Solar radiation is radiated at the electric charge that produces on silicon chip by a grid line enrichment of metal, then is transferred on the main grid line, and generation current generates electricity.But solar battery sheet in the market is because a grid line is straight line, and total length is short, and a little less than the ability of enrichment electric charge, a large amount of electric charges that produced by illumination are not by enrichment, so solar battery sheet generating efficiency in the market is low.If but change on a large scale technique and production equipment, high cost so, medium and small manufacturer can't bear.How in the situation that not Replacement procedure equipment transform simply and easily solar battery sheet, make it to improve generating efficiency, just those skilled in the art's problem that need to solve.
The utility model content
The purpose of this utility model is to overcome the defective that exists in prior art, and a kind of solar battery sheet sensitive surface grid line structure of simple and convenient raising solar battery sheet generating efficiency is provided.
For achieving the above object, the technical solution of the utility model is a kind of solar battery sheet sensitive surface grid line of design, it is characterized in that, the conductive line of described grid line undulate, described conductive line is attached to the silver slurry layer of solar battery sheet sensitive surface by silk screen printing, also adhere on described silver slurry layer due to the vertical strip shaped electric poles layer of conductive line.
In order to guarantee the light-receiving area in solar battery sheet front, preferred technical scheme is that the gap between described corrugated conductive line is more than or equal to 0.3mm.
In order to guarantee the light-receiving area in solar battery sheet front, further preferred technical scheme is that the width of described strip shaped electric poles layer is less than or equal to 1mm.
Advantage of the present utility model and beneficial effect are: this solar battery sheet sensitive surface grid line is not changing existing technique, do not change in the situation of production equipment, can promote the ability of solar battery sheet enrichment electric charge, thereby improve the generating efficiency of solar battery sheet.
Description of drawings
Fig. 1 is the structural representation of the utility model solar battery sheet sensitive surface grid line.
In figure: 1, solar battery sheet; 2, sensitive surface grid line; 3, silver slurry layer; 4, strip shaped electric poles layer.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, the utility model is a kind of sensitive surface grid line 2 of solar battery sheet 1, the conductive line of this grid line undulate, conductive line is attached to the silver slurry layer 3 of solar battery sheet 1 sensitive surface by silk screen printing, also adhere on silver slurry layer 3 due to the vertical strip shaped electric poles layer 4 of conductive line.
In order to guarantee the light-receiving area in solar battery sheet front, preferred embodiment is that the gap between corrugated conductive line is more than or equal to 0.3mm in the utility model.
In order to guarantee the light-receiving area in solar battery sheet 1 front, further preferred embodiment is that the width of strip shaped electric poles layer 4 is less than or equal to 1mm in the utility model.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
