Below.
The dielectric substrate of solution state battery body upper and lower surface coating can by spin coating, spraying coating, wet coating,
The method such as drop coating or silk-screen printing is realized, by the sintering under uniform temperature after coating, can in cell piece upper and lower surface shape
Into fine and close insulating barrier, this series of technical process can realize extensive operation by streamline.
The preparation method of anti-PID solar battery sheets is:A. solution is prepared:Insulating materials PMMA is dissolved in tetrahydrofuran etc.
In organic solvent, density is about 1.1-1.9KG/L, so that the organic solution of PMMA is obtained, for forming solar battery sheet
Surface(Smooth surface)Insulating barrier.
In mass ratio 8% weighs silica, is stirred by high speed machine, is dispersed in above-mentioned PMMA solution, so that
The PMMA solution containing silica is obtained, for forming battery body lower surface(Back surface field face)Insulating barrier.
In mass ratio 15% weighs the organic coordination compound of europium ion, is stirred by high speed machine, is dispersed in above-mentioned PMMA
In solution, so that the PMMA solution of the organic coordination compound containing europium ion is obtained, for forming battery body upper surface(Light
Face)Insulating barrier, adding the purpose of the organic coordination compound of above-mentioned europium ion is:By what is changed under conversion on fluorescence or fluorescence
Principle, by before sunshine that script conventional batteries can not be used or that utilization rate is relatively low such as 300nm or 1000nm it
Infrared light afterwards is transformed into solar cell optimum utilization wave band, improves component power.
B. solar battery sheet surface is applied:The positive and negative main gate line of cell piece is protected using half tone or mask,
The PMMA solution of the organic coordination compound containing europium ion is coated in by solar cell by silk-screen printing or spray Tu side respectively
The upper surface of piece(Smooth surface)Non-master gate part, and the PMMA solution containing calcium oxide is coated uniformly on solar battery sheet
Lower surface(Back surface field face)Non-master gate part.Cell piece is put into sintering furnace less than 260 degree again and is sintered 20min, etc.
After organic solvent volatilization is dry, the insulating barrier of densification can be formed in the smooth surface of battery and back surface field face, as shown in Figure 3.Now,
These batteries are carried out electrical connection, the encapsulation of normal procedure again, the component for obtaining will have very in terms of PID and washmarking, black line
Big advantage.
For PID, in addition to normal component package is protected, due to foring other one layer of densification again on cell piece surface
Uniform PMMA insulating barriers, it with cell piece surface in the insulating barrier that battery surface is formed by packaging adhesive films such as EVA than only being tied
Close more preferably, evenly and insulating properties is more preferable(Duplicate protection).The PMMA insulating barriers will prevent leakage current electric charge in solar-electricity
The accumulation of pool surface, effectively prevents due to the power attenuation that electrical potential difference causes.
And for washmarking or black line, cell piece upper surface(Smooth surface)The insulating barrier of coating has a certain degree of to steam
Intercept, further, since in cell piece lower surface(Back surface field face)The insulating barrier containing drier calcium oxide is coated with, is can absorb from group
At part backboard invade steam so that effectively intercept steam from cell piece it is hidden split or fragmentation at enter.By cell piece upper table
Face(Smooth surface)And lower surface(Back surface field face)Insulating barrier dual barrier, the moisture content of component internal can be greatly reduced,
So as to reduce or avoid the generation of the silver oxide for causing black line or washmarking.It is easy that the structural manufacturing process is realized, can large-scale industry
Metaplasia is produced, and be can be widely applied to during component is produced effectively to prevent component PID phenomenons and washmarking phenomenon.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
