Abstract
The utility model discloses a kind of novel solar cell slices, including a silicon chip, some equally distributed main gate lines and some equally distributed thin grid lines are printed with the silicon chip, the main gate line is five, the width of the main gate line is 0.6 0.8 millimeters, and the width of the thin grid line is 30 32 microns.As a result of five main gate lines, so that cell piece has relatively low series resistance and higher conversion efficiency, the power output of unit area component greatly improved, effectively raise component efficiency, on the basis of existing four main gate lines cell piece, further increase the volume production efficiency of battery, the hit rate of 60 crystal policrystalline silicon battery component 270W output power is substantially improved, simultaneously, using the grid line structure of more line, less with expensive silver paste dosage, the production cost of cell piece can be reduced.
Description
Technical field
A kind of solar battery sheet is the utility model is related to, it is specifically a kind of by setting five main gate lines to reach
Relatively low series resistance and the high performance solar batteries piece of Geng Gao conversion ratio, belong to technical field of photovoltaic power generation.
Background technology
As global energy day is becoming tight, pollution is on the rise, and clean energy resource is largely used, solar energy because its take no
To the greatest extent, it is most commonly used clean energy resource.Solar energy carries out opto-electronic conversion to realize by solar cell, and solar-electricity
Pond piece is the core component of solar cell.Solar battery sheet is by silicon chip and by being screen printed onto thereon intersecting in length and breadth
Grid line is formed, and 4 main gate lines is typically provided with existing solar battery sheet, its width is 1 millimeter, also vertical with main gate line
Some intersecting parallel secondary grid lines, its width are 34 microns.Although the solar battery sheet of this structure has reached
18.5% conversion ratio, but this conversion ratio is unable to reach the requirement of the 270W polycrystalline components of " leader's plan ", meanwhile, it is
Save expensive silver paste, it will usually two ends of main gate line are provided with wedge angle, can set several empty in the centre of main gate line
Chamber, this can cause the pulling force of main gate line inadequate again.
Utility model content
To overcome drawbacks described above, the utility model, which aims to provide one kind, can effectively improve conversion ratio, while save silver paste
The solar battery sheet used.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of novel solar cell slices, including one
Individual silicon chip, some equally distributed main gate lines and some equally distributed thin grid lines, the master are printed with the silicon chip
Grid line is five, and the width of the main gate line is 0.6-0.8 millimeters, and the width of the thin grid line is 30-32 microns.
As a result of five main gate lines so that cell piece has relatively low series resistance and higher conversion efficiency, greatly
Width improves the power output of unit area component, effectively raises component efficiency, in the base of existing four main gate lines cell piece
On plinth, the volume production efficiency of battery is further increased, 60 crystal policrystalline silicon battery component 270W output power is substantially improved
Hit rate, meanwhile, using the grid line structure of more line, the production of cell piece can be reduced less with expensive silver paste dosage
Cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- silicon chips, 2- main gate lines, the thin grid lines of 3-.
Embodiment
As shown in figure 1, the utility model discloses a kind of novel solar cell slices, including a silicon chip 1, the silicon chip
Some equally distributed main gate lines 2 and some equally distributed thin grid lines 3 are printed with 1, it is in summary, and existing general
The structure of logical solar battery sheet is basically identical.
It is five that the innovative point of solar battery sheet described in the utility model, which essentially consists in the main gate line 2, the master
The width of grid line 2 is 0.6-0.8 millimeters, and the width of the thin grid line 3 is 30-32 microns.Sign and limited in existing production technology,
In actual production process, for the width of usual main gate line 2 between 0.7-0.8 millimeters, the width of thin grid line 3 is 31-32 microns
Between, compared with common batteries piece, the dosage of silver paste can reduce more than 5%, and the efficiency of cell piece improves more than 5%.Meanwhile
Two ends due to eliminating main gate line 2 are provided with wedge angle, and middle several cavitys set of main gate line 2 so that main gate line 2
Pulling force greatly improves so that the performance of cell piece is more stable.
