Abstract
The utility model discloses a multistage grid line solar wafer, the combined solar cell panel comprises a solar cell sheet, solar wafer's front is equipped with perpendicular crisscross first order electrode and the second level electrode that sets up, be equipped with vertically third level electrode on first order electrode or the second level electrode, the width of third level electrode is less than first order electrode and second level electrode, and the density of third level electrode is greater than the density of first order electrode and second level electrode. The utility model discloses a multistage grid line solar wafer increases thinner third level electrode on the basis of two -stage electrode to improve the coverage density of electrode, increase the collection of slight electric current, and finally assemble on figure and the busbar electrode. This patent keeps under the unchangeable basically circumstances keeping the present electrode whole area, and the optimal design is the coverage density of live width, figure and the electrode line of electrode at the same level not, improves the collection ability of electric current.
Description
Technical field
This utility model relates to technical field of solar batteries, particularly to a kind of multistage grid line solar battery sheet.
Background technology
The gate line electrode in silicon solar cell front is two-stage form at present, i.e. Busbar and figure two-stage electrode, but such two-stage electrode is less due to the coverage density of electrode, for the collection of minute current, there is certain defect, it is impossible to preferably improve the capacity gauge to electric current.
Summary of the invention
In order to overcome drawbacks described above, this utility model provides a kind of multistage grid line solar battery sheet that can increase electric current collection ability.
This utility model be the technical scheme is that a kind of multistage grid line solar battery sheet to solve its technical problem, including solar battery sheet, the front of described solar battery sheet is provided with first order electrode and the second level electrode that vertical interlaced is arranged, described first order electrode or second level electrode are provided with vertical third level electrode, the width of described third level electrode is less than first order electrode and second level electrode, and the density of third level electrode is more than first order electrode and the density of second level electrode.
As further improvement of the utility model, the width of described third level electrode is between 1 to 30 micrometers.
As further improvement of the utility model, the average distance of described two adjacent third level electrodes is 50 microns to 1.5 millimeters.
The beneficial effects of the utility model are: multistage grid line solar battery sheet of the present utility model is on the basis of two-stage electrode, increase thinner third level electrode, to improve the coverage density of electrode, increase the collection of minute current, and finally converge on figure and busbar electrode.This patent, in the case of maintaining the current electrode gross area to keep being basically unchanged, optimizes the design live width of electrode the most at the same level, number and the coverage density of electrode wires, improves the capacity gauge of electric current.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Figure indicates: 1-solar battery sheet；2-first order electrode；3-second level electrode；4-third level electrode.
Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
Fig. 1 shows a kind of embodiment of a kind of multistage grid line solar battery sheet of this utility model, including solar battery sheet 1, the front of described solar battery sheet 1 is provided with first order electrode 2 and the second level electrode 3 that vertical interlaced is arranged, described first order electrode 2 or second level electrode 3 are provided with vertical third level electrode 4, the width of described third level electrode 4 is less than first order electrode 2 and second level electrode 3, and the density of third level electrode 4 is more than first order electrode 2 and the density of second level electrode 3.The width of described third level electrode 4 is between 1 to 30 micrometers.The average distance of described two adjacent third level electrodes 4 is 50 microns to 1.5 millimeters.Described third level electrode 4 is by methods such as sputter coatings, particularly as follows: first the hollowed-out mask processed, such as thin polymer film, or silica-base material, is fitted on cell piece, then puts in vacuum coating equipment, cavity body vacuum is not less than 10E-3Pa, it is passed through argon, flow 5-100sccm, then carries out sputter coating.
