Abstract
The utility model discloses a facade grid line electrode of a crystalline silicon solar cell. The facade grid line electrode comprises main grid lines and thin grid lines, which are arranged on the facade of the solar cell. The facade grid line electrode is characterized in that at least two main grid lines are arranged, and each main grid line is equidistantly arranged in parallel; and the thin grid lines comprise a plurality of first thin grid lines vertical to the main grid lines and arranged in parallel, second thin grid lines arranged to be parallel to the main grid lines and third thin grid lines connected on the periphery of the facade of the solar cell. In the structure, each main grid line and each thin grid line are mutually connected, so that the current with broken grid can be collected on the main grid line even if the thin grid line has broken grid condition, thereby improving the electric performance efficiency of the solar cell; and besides, an operator generally wipes a screen printing plate after finding the obvious broken grid condition during the printing process, while the structure can allow small amount of broken grids, thereby reducing the wiping action, namely, reducing the printing difficulty, and saving the sizing agent and the production time.
Description
Technical field
The utility model relates to technical field of solar cells, is specifically related to a kind of crystal-silicon solar cell front gate line electrode.
Background technology
The developing direction of crystal-silicon solar cell is low-cost, high efficiency.It is when PN junction is made in diffusion in the liquid phosphorus source that present conventional batteries is raised the efficiency way; Carry out low phosphorus and mix to form higher square resistance, can reduce surface recombination like this, the spectral response of raising sunlight intermediate waves with emission layer is compound; But because the raising of square resistance; The electrode contact resistance also can increase, so must increase moire grids density to reduce the electrode contact resistance, improves the cell photoelectric conversion efficiency.
When increasing moire grids density, also increased the shading area of gate line electrode, can reduce battery conversion efficiency equally, in order to address this problem, this just necessarily requires gate line electrode to want thin as far as possible.The gate line electrode width of silk screen printing at present the most carefully reaches 40 microns, has strengthened the printing difficulty so again: in printing process, occur disconnected grid, the infull phenomenon of printing easily, influence the collection of electrode pair electric current, reduced battery conversion efficiency; And this half tone that is used for the printing of thin grid line is wanted frequent wiping, will waste the production time, and the part slurry sticks to and also wasted slurry on the dust-free paper simultaneously, if undue force also can make the screen cloth explosion of tightening during wiping, has increased production cost.
The utility model content
The utility model provides a kind of and can help electric current collection effect, raising printing quality, the crystal-silicon solar cell front gate line electrode that reduces production costs to the above-mentioned deficiency of prior art.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of crystal-silicon solar cell front gate line electrode; Comprise the main grid line and thin grid line that are arranged on solar cell front (sensitive surface); It is characterized in that: described main grid line is at least two, and every main grid line equidistant parallel is arranged; Described thin grid line comprises many first thin grid lines vertical with the main grid line and that be arranged in parallel with each other, with the second thin grid line of main grid line parallel arrangement, and the 3rd thin grid line that connects the positive periphery of solar cell.
Adopt said structure,,, also can make the electric current of disconnected grid be pooled to above the main grid line, improved the electrical property efficient of solar battery sheet even disconnected grid take place thin grid line because every main grid line all is connected to each other with thin grid line; In addition, ordinary circumstance is in printing process; The operator can carry out the half tone wiping action after finding obviously disconnected grid usually, but this structure can allow to take place a small amount of disconnected grid; Therefore, reduced wiping action, be equivalent to reduce the printing difficulty, saved slurry and production time.
As preferably, described main grid line is 3, and described 3 main grid lines are equidistantly arranged each other, and spacing distance is 52mm, and when guaranteeing disconnected grid, electric current evenly is pooled on the main grid line fully.
As preferably, the described second thin grid line of arranging with the main grid line parallel is 2, and 2 second thin grid lines are arranged at the centre position of adjacent two main grid lines respectively, thereby realizes the purpose of even collected current.
Description of drawings
Accompanying drawing is the structural representation of the utility model crystal-silicon solar cell front gate line electrode.
As shown in the figure: 1. main grid line, the 2. first thin grid line, the 3. second thin grid line, 4. the 3rd thin grid line.
Embodiment
Through specific embodiment the utility model is described in further detail below, but the utility model not only is confined to following examples.
As shown in the figure; A kind of crystal-silicon solar cell front gate line electrode for the utility model; Comprise the main grid line 1 and thin grid line that are arranged on solar cell front (sensitive surface), it is characterized in that: described main grid line 1 is at least two, and every main grid line 1 equidistant parallel is arranged; Described thin grid line comprises many first thin grid lines 2 vertical with the main grid line and that be arranged in parallel with each other, with the second thin grid line 3 of main grid line parallel arrangement, and the 3rd thin grid line 4 that is connected the positive periphery of solar cell.
Adopt said structure,,, also can make the electric current of disconnected grid be pooled to above the main grid line, improved the electrical property efficient of solar battery sheet even disconnected grid take place thin grid line because every main grid line all is connected to each other with thin grid line; In addition, ordinary circumstance is in printing process; The operator can carry out the half tone wiping action after finding obviously disconnected grid usually, but this structure can allow to take place a small amount of disconnected grid; Therefore, reduced wiping action, be equivalent to reduce the printing difficulty, saved slurry and production time.
When guaranteeing disconnected grid, electric current evenly is pooled on the main grid line fully, and as preferably, described main grid line is 3, and described 3 main grid lines are equidistantly arranged each other, and spacing distance is 52mm.
In order to realize the purpose of even collected current, as preferably, the described second thin grid line 3 that is arranged in parallel with main grid line 1 is 2, and 2 second thin grid lines 3 are arranged at the centre position of adjacent two main grid lines 1 respectively.
The said structure of present embodiment shown in the drawings; Gate line electrode is collected current more effectively; The particularly existence of the second thin grid line 3 and the 3rd thin grid line 4; Assurance can be connected with main grid line 3, thereby can effectively reduce the influence that disconnected grid cause electric current, guarantees that fully electric current is pooled on the main grid line.
