Abstract
The utility model provides a scraper for reworking of inferior printing of a solar battery back electrode, which is characterized in that: the scraper comprises a soft handle; the scraper body is provided on the handle; and the bottom of the scraper body is provided with a blade. After the scraper of the utility model scraps the slurry of the back electrode with inferior printing, the back electrode can be directly printed again, thereby effectively preventing low-efficiency back electrode, inferior-appearance back electrode and large amount of broken back electrodes. Simultaneously cleaning liquid such as large amount of alcohol and dust-free cloth, which are required in the routine wet-method reworking, are saved. Furthermore the scraped slurry can be reused after recovery treatment, thereby reducing the reworking cost.
Description
Technical field
The utility model relates to a kind of to the bad instrument of doing over again of back electrode of solar cell printing.
Background technology
At present the solar cell silkscreen process mostly adopts organic solvent such as alcohol that bad scouring of the printing of backplate done over again; This wet method is cleaned backplate; Be easy to cause fragment, and can cause battery sheet positive wearing and tearing and pollution, therefore this doing over again causes the process percentage of damage to increase; Yield rate reduces, and final conversion efficiency is very low.
Summary of the invention
The purpose of the utility model provides and a kind ofly can not cause fragment and do not wear and tear and pollute the positive instrument of battery sheet.
In order to achieve the above object, the technical scheme of the utility model has provided the scraper of the bad usefulness of doing over again of a kind of solar cell back electrode printing, and it is characterized in that: comprise soft handle, cutter hub is located on the handle, is provided with blade in the bottom of cutter hub.
After using the utility model scraper to strike off the bad back electrode slurry of printing; Can directly print back electrode once more; The effective generation that must avoid poor efficiency sheet, outward appearance to reduce sheet and a large amount of flinders; Also practiced thrift cleaning fluid and non-dust cloths such as more alcohol that conventional wet method is done over again to be needed simultaneously, and can reduce rework cost utilizing once more after the slurry recycling that scrapes off.
Description of drawings
Fig. 1 prints the scraper sketch map of the bad usefulness of doing over again for a kind of solar cell back electrode that the utility model provides.
The specific embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, a kind of solar cell back electrode that provides for the utility model prints the scraper of the bad usefulness of doing over again, and comprises soft handle 1, and cutter hub 2 is located on the handle 1, is provided with blade 3 in the bottom of cutter hub 2.
During use; At first put into drying oven to the bad silicon chip of backplate printing; Under 250-300 degree centigrade temperature, dry, on the back electrode slurry, be stained with a small amount of alcohol then, the slurry of oven dry can keep solidifying after running into alcohol; Last scraper side direction on the back electrode slurry firmly can be easy to into the piece scraped clean to the slurry on the silicon chip.
Below be the implementation result contrast:
| Charge | Number | Pmpp | Uoc | Isc | Rs | Rsh | FF | NCell | Irev2 |
| Normal sheet | 23 | 2.563 | 0.633 | 5.181 | 5.65 | 38.68 | 78.1 | 17.25 | 0.4 |
| Wipes of alcohol is developed a film | 19 | 2.32 | 0.622 | 5.292 | 12.05 | 13.5 | 70.34 | 15.61 | 2.49 |
Table 1. ordinary production and the battery piece performance contrast of using alcohol to clean
| Charge | Number | Pmpp | Uoc | Isc | Rs | Rsh | FF | NCell | Irev2 |
| Normal sheet | 25 | 2.578 | 0.630 | 5.247 | 5.59 | 31.62 | 77.94 | 17.35 | 0.47 |
| Present embodiment | 27 | 2.572 | 0.630 | 5.251 | 6.01 | 35.80 | 77.62 | 17.32 | 0.47 |
Table 2. ordinary production and the battery piece performance contrast of using the utility model to do over again:
Can find out that from above data contrast use alcohol to clean the battery sheet after doing over again, series connection Rs and leakage current Irev2 are seriously bigger than normal, finally cause its conversion efficiency Ncell very low.And use novel each unit for electrical property parameters of battery sheet and the ordinary production sheet of handling of doing over again of this use not have too big-difference, so its conversion efficiency Ncell and normal sheet basically identical.
