2~3 main grids can be provided on the front of cell piece, main grid intersects vertically with thin grid and connects, and main grid can will be on each thin grid
Electric current collection to together, and the welding by being welded on main grid transfers out, and the material used in the main gate line is typically all
Silver paste material, due to silver paste material price costly, so adding the production cost of solar battery sheet.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can save silver paste materials'use amount, and reduce life
Produce the solar battery sheet of cost.
The utility model is the technical scheme adopted is that a kind of solar battery sheet, including positive electrode surface and setting
In the positive electrode grid line of positive electrode surface, the positive electrode grid line is mutually parallel including at least one main gate line and several
Thin grid line, the positive electrode grid line further include the secondary grid line for the end for alternately connecting adjacent two thin grid line successively, the pair grid
The width of line is less than or equal to main grid line width.
The beneficial effects of the utility model are：Using the structure, the end of adjacent two thin grid line is alternately connected successively
Secondary grid line can collect the electric current on thin grid line, and the width of secondary grid line instead of the main gate line of one or a few in original technology
Less than or equal to the width of main gate line, the usage amount of silver paste material can be directly saved, so as to reduce cost；Use alternately connection
The secondary grid line of the end of adjacent two thin grid line replaces one or a few main gate line in original technology, increases cell piece
Light-receiving area, so as to improve the efficiency of light absorption of cell piece.
As priority, the main gate line intersects vertically with the thin grid line and connects, the main gate line include first side and
Second side, the first side are provided with the first recess, the second side and thin grid line intersection with thin grid line intersection
The second recess corresponding with the first recess on first side is provided with, using the structure, jagged main gate line is set still
The function of playing and collect the electronics on thin grid line can be connected with thin grid line, and referring now to the main gate line in crude oil technology
Volume is reduced, the usage amount of silver paste material thus can be further saved, reduce being fabricated to for solar battery sheet
This.
As priority, the inside of first recess and the second recess is respectively connected with short grid line, using the structure, Ke Yijia
The speed of fast main gate line export electronics, so as to improve the photoelectric conversion efficiency of solar battery sheet.
As priority, the width of the short grid line is equal to the width of the thin grid line, using the structure, can facilitate the sun
The processing of energy cell piece.
