The silk printing glass is cleaned.According to the size of silk printing glass and battery chip 4, SGP film is cut, makes its size
It coincide with front and back component, to form the first film layers 2 and the second film layers 5.Then, pass through welding procedure on battery chip 4
Busbar is connected, busbar keeps being electrically connected with the terminal box 7 for being located at sub-assembly rearmost.In the present embodiment, it uses
Ordinary glass is as the second substrate 6.Above-mentioned component stacks gradually to form stacked body according to the sequence of such as Fig. 1, is then placed in
In laminating machine.
Then, implement the first lamination stages.Vacuumizing for first stage is preliminary step for laminating technology, the step
The photovoltaic combination of equipment and setting can be adjusted and be prepared with pre-heating technique.In this step, due to solar energy group
Part is located at the middle position of the upper chamber and lower room of laminating apparatus, and upper surface contacts upper chamber, and lower surface is connected to lower room, and equipment is upper
It is isolated from each other between lower room and can be controlled separately its vacuum degree；In this case, upper and lower room is controlled simultaneously as identical vacuum
When degree (for instance in -70kpa between -100kpa, being embodied as -100kpa in the present embodiment), it will be understood that this will so that
Solar components are in preparation state without being subjected to actual pressure.The stacked body in lamination room is carried out by preheating simultaneously
Prepare.In the present embodiment, preheating temperature can be set at 130 DEG C to 150 DEG C, be set as 150 DEG C in the present embodiment.It will too
Positive energy component closes the vacuum chamber (can be referred to as " upper chamber " and " lower room " in laminating apparatus) above and below piece while taking out
Vacuum, until meter pressure reaches -100kpa.The duration between 1200 seconds to 2400 seconds is kept at this temperature and pressure, at this
1800s is kept in embodiment.Preheating and preparation processing for stacked body are implemented in this stage, it will help laminating technology
Implement and obtain the solar components of excellent properties.
Then into technique second stage, i.e. the second lamination stages.In embodiments, second stage can be divided into two again
A sub-stage.In the first sub-stage, by gas filling technology, by the true of the pressure adjustment of the upper chambers of stacked body to less than lower room
Reciprocal of duty cycle.The vacuum degree of upper chamber can be adjusted in the embodiment of the disclosure to gauge pressure -60kpa to -10kpa, in this embodiment party
It is adjusted in case to -30Kpa, while keeping lower chamber pressure is that -100kpa is constant, thus by the adjustment of vacuum degree so that upper chamber is true
Reciprocal of duty cycle is small, and lower room vacuum degree is high, to pressure be conducted from top to bottom to stacked body, and is kept for 900 seconds.In second sub-stage
In, continue to adjust chamber pressure, chamber pressure is -50Kpa in adjustment, further keeps 1200s.Generally speaking, the second lamination rank
The time that section is kept can control between 1500 seconds to 2500 seconds.
In the second lamination stages, the air pressure above solar components is appropriately increased, i.e., is reduced vacuum degree, such as
Too small amount of aeration step can be led to and increase the air pressure in the apparatus cavity above solar components, so that on solar components
The air pressure of side is greater than air pressure below, to realize the conduction of pressure from top to bottom so that solar components substantially by
Lamination pressure from top to bottom.Pressure applied and holding duration are not limited to the present embodiment, and wherein the top of stacked body is true
Reciprocal of duty cycle is gauge pressure -60kpa to -10kpa, and 1500 seconds to 2500 seconds a length of when holding in this stage.
Then, technique enters third lamination stages.In third lamination stages, the stacked body of the second lamination stages will be undergone
It is sent into autoclave.High pressure in autoclave can be set as 1.1 to 2.0Mpa, and the temperature in autoclave can be set to 125
DEG C to 140 DEG C；And the duration kept in autoclave can be set to 30 minutes to 90 minutes.In the present embodiment, setting is high
The temperature for pressing kettle is 125 DEG C, applies positive pressure 1.2Mpa, retention time 60min.
So that stacked body furnace cooling or blow-on are cooling, the solar energy group of final obtained multiple layer consolidation
Part.
Can also include other one or more auxiliary and preliminary process in lamination process provided in this embodiment: for example,
Cleaning is implemented to first substrate 1 and the second substrate 2；First film layers 2 and the second film layers 5 are cut；Busbar 3 is led to
Cross the surface etc. that welding procedure is connected to the generation photoelectric current of battery chip 4.With reference to Fig. 3, thus it is shown that one embodiment of the disclosure
The complete lamination process flow diagram including auxiliary process of solar components.
According to Fig. 3, first implementation solar components pre-treatment step 101.The pretreatment and preparation process include that manufacture is made
For the silk printing glass substrate of first substrate；After producing silk printing glass substrate of the edge with silk-screen region, to silk printing glass
Substrate and glass substrate as the second substrate are cleaned；It carries out simultaneously, for the sanction of SGP film layers ready for use
It cuts, that is done cuts so that the size of SGP film layers is consistent with the size of substrate；Then by the surface of the battery chip manufactured
Busbar in attachment.Thus solar components pre-treatment step 101 is completed.
It then carries out solar components and closes piece step 102.In sequence, sequentially be laid with the second substrate, SGP film layers,
Battery chip with busbar, another SGP film layers and silk printing glass substrate.
After closing piece step, implement the first lamination stages 103, the second lamination stages 104 and in order respectively
Three lamination stages 105.The lamination production of solar components is completed as a result,.
Other embodiments and comparative example
The other optional embodiments of the disclosure set forth below and comparative test.In embodiment 2 to 8, using with reality
The order of placement for applying the identical all parts of example 1, will not be described in great detail herein.Unlike the first embodiment, embodiment 2-8 will be adopted
With the technological parameter in each stage in the specifications parameter and laminating technology different from embodiment 1, therefore embodiment 2- will be omitted
The description of concrete technology in 8.The parameter in each stage and performance summary used by related embodiment and comparative example are as follows:
The laminating technology of 1 solar components of table
In the performance evaluation of above-mentioned technique, " tensile strength " and " lamination " is according to the opposite knot compared between product
Fruit is given a mark, and optimal result is 5 points, and most bad result is 1 point, and " tensile strength " is on active service with actual product in external wall of high-rise building
Whether it damages after 6 months or strain cracking is observation standard.And after lamination view lamination in solar components whether
It is observation standard there are the bad engagement result such as bubble, that reflects the quality of laminating technology result of implementation.
From examples detailed above and comparative example as it can be seen that achieving excellent result using the solar components of two layers of SGP film.Its
Even if the thickness of middle SGP film layers is as thin as 0.76mm (such as embodiment 3) or lower, in conjunction with the lamination work of embodiment of the disclosure
Skill can also obtain good connection and intensity effect.And when use one layer of SGP film, with PVB film layers collocation in use,
Achieve the effect for making us receiving, such as embodiment 2.And various battery chip types have with the technique of embodiment of the disclosure
Good compatibility.In the comparative test of series, it also seen that the relevant technologies and not being inconsistent with embodiment of the disclosure technique
The test result of the product of conjunction.When SGP film layers are excessively thin, connection effect cannot reach best；First film layers and the second glue
