Abstract
The utility model discloses a kind of crystal silicon solar cell sheet, each row main gate line is divided into some sections of interruption, and every section of main gate line is provided with equally distributed hollow out, and described hollow out is the rectangle hollow out be laterally arranged in order; The hollow out main gate line of segmentation can meet the requirement of silicon solar cell sheet end electric performance test, and on the basis decreasing required positive electrode silver slurry consumption, the positive electrode silver slurry in main gate line still can meet components welding pulling tension requirements, reduces production cost.
Description
Technical field
The utility model relates to photovoltaic silicon field of batteries, is specifically related to a kind of solar battery sheet.
Background technology
At present, what the crystal silicon solar energy battery positive electrode of main flow adopted is main grid and the design of secondary grating, and main grid for collecting the electric current of secondary grid accumulation, and at assembly end for welding busbar, derives the electric current that cell piece sends.Because assembly end is for the requirement of welding of battery film pulling force, main grid mainly adopts straight strip type or the design of segmentation straight strip type, and the shortcoming of this structure is the increase in the consumption of positive electrode silver slurry, adds production cost.
Utility model content
Utility model object: the purpose of this utility model is for the deficiencies in the prior art, provides a kind of under the requirement of Assurance component welding pulling force, reduces the crystal silicon solar cell sheet of cell piece main gate line silver slurry consumption.
Technical scheme: a kind of crystal silicon solar cell sheet described in the utility model, each row main gate line is divided into some sections of interruption, and every section of main gate line is provided with equally distributed hollow out; Former straight strip type main gate line is carried out sectional design by this structure, and hollow out is carried out again in the basis of segmentation main gate line, significantly can reduce the use amount of positive electrode silver slurry, and can meet the demand of positive electrode for welding pulling force.
Preferably, described hollow out is the rectangle hollow out be laterally arranged in order; Adopt rectangle hollow out to form the pierced pattern of array distribution, the requirement of silicon solar cell sheet end electric performance test can either be met, assembly end welding pulling tension requirements can be met again, and greatly reduce the consumption of positive electrode silver slurry, reduce production cost.
Preferably, the quantity of described main gate line is 3 ~ 5 row, can meet different technology controlling and process standards, ensures the normal conversion efficiency of cell piece while promoting welding pulling force.
Preferably, the width of described main gate line is 0.9 ~ 1.5um, can meet welding pulling force when using different silver slurry, and can meet the design of grid line shading-area.
Beneficial effect: the hollow out main gate line of segmentation can meet the requirement of silicon solar cell sheet end electric performance test, on the basis decreasing required positive electrode silver slurry consumption, positive electrode silver slurry in main gate line still can meet components welding pulling tension requirements, reduces production cost.
Accompanying drawing explanation
Fig. 1 is utility model silicon solar cell positive electrode structure schematic diagram;
Fig. 2 is the partial enlargement hollow out schematic diagram of one section of main grid A in Fig. 1.
Detailed description of the invention
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
embodiment: a kind of crystal silicon solar cell sheet, as shown in Figure 1, has 3 row main gate line 1 altogether, the width of main gate line 1 is 1.2um, each row main gate line 1 is divided into is interrupted discontinuous 8 sections, and as shown in Figure 2, every section of main gate line 1 is provided with laterally evenly distributed successively rectangle hollow out 2; Thin grid line is collected cell piece surface current and is pooled to main gate line 1, is finally passed to load end by main gate line 1.Compared with prior art, the present embodiment not only can effectively improve positive electrode printing effect, significantly reduces the use amount of positive electrode silver slurry, and can ensure the demand of grid for welding pulling force of confluxing, and improves cell piece photoelectric conversion efficiency, reduces production cost.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the present utility model not departing from claims definition, various change can be made in the form and details to it.
