At present, the types of solar cells are continuously increased, the application range is increasingly wide, and the market scale is gradually enlarged. Solar power generation has two modes, one is a light-heat-electricity conversion mode, and the other is a light-electricity direct conversion mode. The light-heat-electricity conversion mode is to generate electricity by utilizing the heat energy generated by solar radiation, generally, a solar heat collector converts the absorbed heat energy into steam of a working medium and then drives a steam turbine to generate electricity. The former process is a light-to-heat conversion process; the latter process is a heat-electricity conversion process, and like ordinary thermal power generation, solar thermal power generation has the disadvantages of low efficiency and high cost, and the investment of the solar thermal power generation is estimated to be at least 5-10 times more expensive than that of an ordinary thermal power station; the direct photoelectric conversion mode is a mode of directly converting solar radiation energy into electric energy by using a photovoltaic effect, and a basic device for the photoelectric conversion is a solar cell. The solar cell is a device which directly converts solar energy into electric energy due to photovoltaic effect, and is a semiconductor photodiode. When a plurality of batteries are connected in series or in parallel, a solar battery matrix with larger output power can be formed. Solar cells are a promising new power source with three advantages of permanence, cleanliness and flexibility. The solar cell has long service life, and can be used for a long time by one-time investment as long as the sun exists; compared with thermal power generation and nuclear power generation, the solar cell does not cause environmental pollution.

The laminating machine used in the prior production is an oil heating laminating machine, heat conducting oil is heated to a set temperature, and the heat conducting oil is circulated under a heating plate through a pipeline, so that the heating plate reaches the set temperature. However, the heat transfer oil heating system has the phenomena of coking and coking in the use process, the service cycle is short, the chemical characteristics of the heat transfer oil heating system have certain corrosion effect on the system, the oil leakage phenomenon and the pungent and peculiar smell often occur in the circulation process, the service cycle of the heat transfer oil is short, the heat transfer oil needs to be replaced periodically, the used waste liquid cannot be recovered, and the operation cost is increased.

In the above scheme, through the setting of outsourcing panel beating for the installation of magnetic energy hot plate is more firm, through the setting of support, is convenient for the installation of magnetic energy hot plate.
In a preferred scheme, the magnetic energy module 13 comprises an insulating plate 21, a high-frequency coil 22 and a shielding cover 23; a plurality of high-frequency coils 22 are uniformly arranged and fixed on the insulating plate 21 through fixing bolts 24; a first magnetic material 25 is coated inside each of the high-frequency coils 22, and a second magnetic material 26 is coated on the insulating plate 21 between the high-frequency coils 22; the shield cover 23 is provided outside the insulating plate 21 and the high-frequency coil 22, and the shield cover 23 is filled with a heat insulating material 27.
In a preferred embodiment, the method further comprises:
and the temperature control system comprises a PID closed-loop control system and a time relay which are respectively connected with the magnetic energy heating plate 8, and the time relay is also connected with the vacuum pipeline 6 so as to realize the temperature control of the magnetic energy heating plate 8, the heating time and the air pressure control of the upper vacuum chamber 4 or the lower vacuum chamber 5.
In the above scheme, the closed-loop control system (closed-loop control system) is characterized in that the output (controlled quantity) of the controlled object of the system is fed back to influence the output of the controller to form one or more closed loops. The closed-loop control system has positive Feedback and Negative Feedback, if the Feedback signal is opposite to the system set value signal, it is called Negative Feedback (Negative Feedback), if the polarity is the same, it is called positive Feedback, and the general closed-loop control systems all adopt Negative Feedback, also called Negative Feedback control systems. Therefore, through the setting of the PID closed-loop control system, when the magnetic energy heating plate reaches the preset temperature, the laminator can automatically regulate and control the output power of the magnetic energy module through PID, so that the heating plate can maintain constant temperature, and the temperature deviation of the laminator in the working process is within 3 ℃; in addition, the time of evacuation directly determines whether the air in the gap between the packaging materials and the gas generated during the evacuation time of lamination can be removed to eliminate air bubbles in the assembly, and at the same time, a pressure difference can be generated in the laminating machine to generate the pressure required in the lamination process. Thus, by setting the time relay, when different lamination times are needed when lamination is carried out at different temperatures, the vacuumizing and lamination time can be changed by adjusting the time setting on the time relay. Meanwhile, because the temperature of the EVA is 80 ℃ when the EVA is completely melted, the silica gel plate can be pressed down only after the EVA is completely melted and the optimal melting state is reached, which is most beneficial to removing gas in the assembly, namely reducing the generation of bubbles, according to the data analysis of the test temperature, when the laminator is adopted, the temperature on the assembly can reach 80 ℃ when the assembly is vacuumized for about 5 minutes, and at the moment, the flowability of the EVA is larger, the silica gel plate is pressed down at the moment, the assembly is easy to shift, so that the vacuumizing time can be prolonged to 6 minutes to avoid shifting. While the pressing time corresponds to the pressure exerted on the module during lamination, the longer the inflation time, the greater the pressure. Because the macromolecule formed after EVA crosslinking is loose in general structure, the adhesive film can be more compact after being cured due to the existence of pressure, and meanwhile, the adhesive force of EVA and other materials can also be enhanced, through test data analysis, when the laminating machine is adopted, the laminating time is generally 9 minutes, and the temperature is set to be about 140 ℃, so that a good laminating effect can be achieved.
