Description
Technical field
The present invention relates to battery technology, more particularly to a kind of bonding method of solar cell.
Background technology
The spacecraft overwhelming majority is all powered using solar battery array, and solar battery array needs first in process of production
Solar cell piece is connected to form solar battery string, then solar battery string is pasted on substrate, at present the conventional space sun
The solar cell method of attaching of cell array, the regularity pasted for solar cell, the control effect of flatness be not good.
The content of the invention
The problem that the present invention is solved is existing space solar battery array regularity, smooth in solar cell taping process
Degree is poor.
To solve the above problems, the present invention provides a kind of bonding method of solar cell, and the method comprises the following steps：
Step one, the lower surface of screening glass is pasted onto the upper surface of solar battery string, through hole and the sun on screening glass
The protruding parts alignment mutually in flakes of battery strings；
Step 2, is coated with silica gel on substrate, and the solar battery string for pasting screening glass is pasted onto on substrate；
Step 3, the substrate that will paste solar battery string is placed between two pieces of fixed metallic plates, and length is placed on substrate
Square air bag, makes the pressure ratio atmospheric pressure in air bag high to airbag aeration, and the substrate for pasting solar battery string is entered with air bag
Row pressurization simultaneously keeps certain hour；
Step 4, to air bag deflation, then takes out air bag and substrate, removes screening glass.
Further, more than the length of solar battery string, the width of screening glass is less than solar cell for the length of the screening glass
The width of string, mutually protruding parts in flakes output through hole to screening glass correspondence, the length and width of through hole be respectively greater than the length of protruding parts,
It is wide.
Further, more than the length of solar battery string, the width of screening glass is less than solar cell for the length of the screening glass
The width of string, mutually protruding parts in flakes output through hole to screening glass correspondence, the length and width of through hole be respectively greater than the length of protruding parts,
It is wide.
Further, the screening glass is made of light basis weight material, preferably PET.
Further, during inflation the air bag pressure ratio atmospheric pressure 4~20kPa high.
Further, the time that the air bag is pressurizeed to the substrate for pasting solar battery string is more than 4 hours.
Compared with prior art, the present invention has advantages below：
1st, because solar battery string is protected using screening glass, can prevent solar battery string from being distorted in taping process
Deformation or under pressurised conditions battery strings produce sliding influence regularity.
2nd, due to carrying out entire pressurisation to substrate using air bag, it is ensured that the flatness that solar battery string is pasted.
Brief description of the drawings
Fig. 1 is the schematic top plan view of current solar battery string；
Fig. 2 is the schematic side view of current solar battery string；
Fig. 3 is the structural representation of screening glass of the invention；
Fig. 4 is the schematic diagram of entire pressurisation method of the invention.
Specific embodiment
To describe technology contents of the invention, structural feature, institute's reached purpose and effect in detail, below in conjunction with embodiment
And coordinate accompanying drawing to be described in detail.
As depicted in figs. 1 and 2, solar battery string 1 is by solar cell piece 11 and mutually 12 constitutes in flakes, in solar battery string
Mutually the front welding of 12 one end and solar cell piece 11 in flakes, the back side weldering of the other end and solar cell piece 11 of 1 centre
Connect, mutually 12 there are protruding parts 121 in the front of solar battery string 1 in flakes.
As shown in figure 3, screening glass 2 is made of light basis weight material, such as PET, the length of screening glass 2 is more than solar battery string 1
Length, less than the width of solar battery string 1, the correspondence of screening glass 1 mutually open in flakes by 12 protruding parts 121 for the width of screening glass 2
Go out through hole 21, the length and width of through hole 21 is respectively greater than the length and width of protruding parts 121.
Further, the lower surface of screening glass 2 scribbles adhesive sticker.
The bonding method of solar battery of the invention is as follows：
Step one, the lower surface of screening glass 2 is pasted onto the upper surface of solar battery string 1, the He of through hole 21 on screening glass 2
Solar battery string 1 mutually in flakes 12 protruding parts 121 be aligned.
Step 2, is coated with silica gel on the substrate 3, and the solar battery string 1 for pasting screening glass 2 is pasted on the substrate 3.
Step 3, as shown in figure 4, the substrate 3 that will paste solar battery string 1 is placed between two pieces of fixed metallic plates 4,
Rectangular air bag 5 is placed on substrate 3, the pressure ratio atmospheric pressure 4~20kPa high made in air bag is inflated to air bag 5, with air bag 5
Substrate 3 to pasting solar battery string 1 is pressurizeed and is kept for more than 4 hours.
Step 4, deflates to air bag 5, then takes out air bag 5 and substrate 3, removes screening glass 2.
Because solar battery string 1 is protected using screening glass 2, can prevent solar battery string 1 from being turned round in taping process
Song deformation or the under pressurised conditions generation of battery strings 1 sliding influence regularity, due to carrying out overall adding to substrate 3 using air bag 5
Pressure, it is ensured that the flatness that solar battery string 1 is pasted.
