Abstract
The invention relates to a printed type battery with fine grid lines. The printed type battery comprises a battery substrate and an electrode laid on the battery substrate; the electrode comprises a plurality of fine grid lines which are parallel to one another and at least two main grid lines perpendicular to the fine grid lines; an auxiliary grid line is connected between each two adjacent fine grid lines; and each two adjacent fine grid lines and the corresponding auxiliary grid line form an 'I' shape. The printed type battery with the fine grid lines is simple in structure, the grid lines which are in I-shaped arrangement are adopted, the absorptivity of the battery piece can be effectively improved, short-circuit current of the battery piece is increased, and the quality of the battery piece is improved.
Description
Technical field
The present invention relates to field of solar cells, the thin grid line battery of especially a kind of printed form.
Background technology
The general in the market front gate line shape that adopts is the pectination grid line; Promptly form jointly by two main grids and many thin grid; Shape under its perfect condition should be with thin grid line do more carefully close more; Should keep good electric current collection ability, reduce the shading loss that it causes at the battery upper surface simultaneously again.
The principle of silk screen printing is exactly the motion of control fluid: before printing, the slurry on the silk screen leaked silk screen because of viscosity more very much not can flow voluntarily; During printing, scraper is pressed into mesh to slurry, under the effect of scraper plate and silk screen; Slurry receives tangential stress and viscosity descends rapidly; And rolling movement, under the effect of rolling pressure, flow through mesh, thereby contact with silicon chip; In the silk screen springback process, be attached on the silicon chip, carry out moulding according to the pattern of half tone.
The screen printing screens that uses in the market, there is following shortcoming in it: the shading area is big, battery sheet absorptivity is low, electric current compiles rate variance.
Summary of the invention
The technical problem that the present invention will solve is: in order to overcome the problem that exists in above-mentioned, provide a kind of printed form thin grid line battery, its project organization rationally and can increase the extinction area of battery sheet effectively.
The technical solution adopted for the present invention to solve the technical problems is: the thin grid line battery of a kind of printed form; Comprise cell substrate and be laid on the electrode on the cell substrate; Described electrode comprises thin grid line that complex root is parallel to each other and at least two and the thin perpendicular main grid line of grid line; Be connected with secondary grid line between the adjacent two thin grid lines, adjacent two thin grid lines and secondary grid line form " worker " font structure.
In order to avoid occurring collapsing the phenomenon at angle in transit, four jiaos of described cell substrate is arcuate structure.
In order to realize being interconnected of electric current between the thin grid line, the live width of described secondary grid line is 50um.
The radical of described main grid line is three, and the live width of every main grid line is 1mm.
The invention has the beneficial effects as follows: the thin grid line battery of described printed form, it is simple in structure, adopts I shape layout grid line, can increase the absorptivity of battery sheet effectively and improve battery sheet short circuit current, has improved the quality of battery sheet.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the overall structure sketch map of the thin grid line battery of printed form of the present invention.
Accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1, cell substrate, 2, grid line carefully, 3, the main grid line, 4, secondary grid line.
Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The thin grid line battery of printed form as shown in Figure 1; Comprise cell substrate 1 and be laid on the electrode on the cell substrate 1, four jiaos of cell substrate 1 is arcuate structure, electrode comprise thin grid line 2 that complex root is parallel to each other with three with the perpendicular main grid line 3 of grid line carefully 2; The live width of every main grid line 3 is 1mm; Be connected with secondary grid line 4 between the adjacent two thin grid lines 2, the live width of secondary grid line 4 is 50um, and adjacent two thin grid lines 2 form " worker " font structure with secondary grid line 4.
The thin grid line battery of printed form of the present invention; Three main grid lines 3 on the cell substrate 1 have been divided into 3 zones with cell substrate 1; Between adjacent two thin grid lines 2, connecting live width is the secondary grid line 4 of 50um, has improved the short circuit current of battery sheet effectively, has improved the quality of product.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
