Abstract
The utility model discloses a photovoltaic cell piece positive electrode screen grid line structure which comprises a main grid line and fine grid lines which are perpendicular to each other. Joints of the main grid line and the fine grid lines are concave interconnecting pieces. By the arrangement of the grooves at the joints of the main grid line and the fine grid lines, the application amount of silver paste can be reduced and conversion efficiency of cell pieces is raised.
Description
Technical field
The utility model relates to a kind of photovoltaic cell positive electrode web plate grid line structure.
Background technology
Existing solar energy power generating is dangerous without exhaustion with it; Pollution-free; Be not subjected to the restriction of resource distribution region; Can generate electricity nearby in electricity consumption place; The energy source quality is high; The user is acceptant on the emotion; Obtain the advantage such as short and electric power system reliable operation of time of energy cost and won market prospects preferably.China's solar-energy photo-voltaic cell sheet production has also entered the epoch of high speed development.The gate electrode line of solar battery sheet is to collect the free electron that silicon solar cell produces.Solar battery sheet positive electrode web plate grid line is generally by vertically disposed thick grid line and thin grid line consist of mutually, the thickness of thick grid line is uniform, lack although such design can be played good electrical connection effect and consumed a large amount of silver slurries, also reduced the transformation efficiency of cell piece.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in prior art, and a kind of photovoltaic cell positive electrode web plate grid line structure that can reduce silver slurry use amount and improve the transformation efficiency of cell piece sheet is provided.
For achieving the above object, the technical solution of the utility model provides a kind of photovoltaic cell positive electrode web plate grid line structure, described photovoltaic cell positive electrode web plate grid line structure comprises mutual vertically disposed main grid line and thin grid line, is the recess connecting portion with thin grid line junction on described main grid line.By the junction at main grid line and thin grid line, the transformation efficiency that groove can reduce silver slurry use amount and improve the cell piece sheet is set.
As preferably, described recess connecting portion is the semicircular arc recess.Such design is a kind of optimization to scheme.
As preferably, described recess connecting portion is the trapezoidal recess shape.Such design is a kind of optimization to scheme.
Advantage of the present utility model and beneficial effect are: by the junction at main grid line and thin grid line, the transformation efficiency that groove can reduce silver slurry use amount and improve cell piece is set.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is another kind of structural representation of the present utility model.
In figure: 1, main grid line; 2, thin grid line; 3, recess connecting portion.
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 depicted in figs. 1 and 2, a kind of photovoltaic cell positive electrode web plate grid line structure, described photovoltaic cell positive electrode web plate grid line structure comprises mutual vertically disposed main grid line 1 and thin grid line 2, is recess connecting portion 3 with thin grid line 2 junctions on described main grid line 1.
Described recess connecting portion 3 is the semicircular arc recess.
Described recess connecting portion 3 is the trapezoidal recess shape.
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.
