Abstract
The invention discloses a rectangular loop positive electrode mesh plate of a crystalline silicon solar cell. The rectangular loop positive electrode mesh plate of the crystalline silicon solar cell comprises a mesh plate body (1), and the mesh plate body (1) is provided with a main gate line (2) and a sub-gate line (3). The rectangular loop positive electrode mesh plate of the crystalline silicon solar cell is characterized in that the sub-gate line (3) comprises rectangular sub-gate lines (4) and diagonal sub-gate lines (5), any two rectangular sub-area gate lines (4) in the same area are arranged on the mesh plate body (1) in a shape like a Chinese character hui, and the diagonal of all the rectangular sub-area gate lines (4) in the same area are connected through the diagonal sub-gate lines (5). According to the rectangular loop positive electrode mesh plate of the crystalline silicon solar cell, the rectangular sub-gate lines which are arranged in the shape like a Chinese character hui and the diagonal sub-gate lines matching with the rectangular sub-gate lines are arranged, so that the shading area and the consumption of silver paste are reduced and the production cost of cells are saved; and the impact caused by poor printing such as gate breaking in the printing process is reduced, the current collection effect is improved, and the realization of high-performance cells is ensured.
Description
Technical field
The present invention relates to the crystal silicon solar batteries technical field, specifically a kind of rectangular-shaped loops positive electrode half tone of enhancing productivity and reducing the crystal silicon solar batteries of silver slurry consumption.
Background technology
The positive electrode half tone is used for the silkscreen process that crystal silicon battery is produced, and the printed silver slurry is sintering also, plays the function of collected current and extraction electrode.The design of half tone figure has determined the printing effect of silver-colored slurry and the collecting effect of electric current, has determined the consumption of silver-colored slurry simultaneously, and final decision the photoelectric transformation efficiency of solar cell.Traditional positive electrode figure is made up of with the secondary grid line vertical with the main grid line the main grid line, mainly plays the function of collected current and extraction electrode.Secondary grid line is too many, the too wide collected current of live width is effective, but the shading area is big, and the photogenerated current of collecting is just little, and photoelectric transformation efficiency will descend, and simultaneously, the consumption of silver slurry also can increase; Few, the line width of secondary grid line then can have influence on the collecting effect of electric current, destroys the integrality of graphic printing simultaneously, finally causes photoelectric transformation efficiency to descend.
Summary of the invention
The objective of the invention is the problem at the prior art existence, a kind of rectangular-shaped loops positive electrode half tone of enhancing productivity and reducing the crystal silicon solar batteries of silver slurry consumption is provided.
The objective of the invention is to solve by the following technical programs:
A kind of rectangular-shaped loops positive electrode half tone of crystal silicon solar batteries, comprise the half tone body, the half tone body is provided with main grid line and secondary grid line, it is characterized in that described secondary grid line comprises the secondary grid line of the secondary grid line of rectangle and diagonal angle, the secondary grid line of any two rectangles of the same area be " returning " font be arranged on the half tone body and the diagonal angle of the secondary grid lines of all rectangles of the same area continuous by the secondary grid line in diagonal angle.
The secondary grid line of described rectangle along the length of side on the length direction of main grid line less than the secondary grid line of rectangle along the length of side on the width of main grid line.
The secondary grid line of described rectangle is not less than the secondary grid line of rectangle along the length of side on the width of main grid line along the length of side on the length direction of main grid line.
The spacing that goes up in the same direction between the secondary grid line of described rectangle is identical.
The present invention has following advantage compared to existing technology:
The present invention is the secondary grid line of rectangle of " returning " font and the secondary grid line in diagonal angle that matches with it by setting, has played the effect that reduces the shading area, reduces silver slurry consumption and conserve batteries production cost; And alleviated the bad influences that cause of printing such as the grid that break when printing, promoted the collecting effect of electric current, guaranteed the realization of high-efficiency battery.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-half tone body; 2-main grid line; 3-secondary grid line; The secondary grid line of 4-rectangle; The secondary grid line in 5-diagonal angle.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1: a kind of rectangular-shaped loops positive electrode half tone of crystal silicon solar batteries, comprise half tone body 1, half tone body 1 is provided with main grid line 2 and secondary grid line 3, wherein secondary grid line 3 comprises the secondary grid line 5 of the secondary grid line 4 of rectangle and diagonal angle, the secondary grid line 4 of any two rectangles of the same area be " returning " font be arranged on the half tone body 1 and the diagonal angle of the secondary grid lines 4 of all rectangles of the same area continuous by the secondary grid line in diagonal angle 5; In general, half tone body 1 is split into the zone more than 2 or 2, and the secondary grid line 3 in each zone is independently.For the length of side of the secondary grid line 4 of rectangle, the secondary grid line 4 of the rectangle of general the same area along the length of side on the length direction of main grid line 2 less than the secondary grid line 4 of rectangle along the length of side on the width of main grid line 2; Perhaps the secondary grid line 4 of the rectangle of the same area is not less than the secondary grid line 4 of rectangle along the length of side on the width of main grid line 2 along the length of side on the length direction of main grid line 2.For strengthening printing effect, the spacing that goes up in the same direction between the secondary grid line 4 of the rectangle in the same area is identical in addition.
The present invention is the secondary grid line 4 of rectangle of " returning " font and the secondary grid line 5 in diagonal angle that matches with it by setting, has played the effect that reduces the shading area, reduces silver slurry consumption and conserve batteries production cost; And alleviated the bad influences that cause of printing such as the grid that break when printing, promoted the collecting effect of electric current, guaranteed the realization of high-efficiency battery.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of doing on the technical scheme basis all falls within the protection domain of the present invention; The technology that the present invention does not relate to all can be realized by prior art.
