Description
Technical field
The present invention relates to the manufacture method of device of solar generating, particularly be used for the manufacture method of photovoltaic-building integrated solar photovoltaic module.
Background technology
Existing solar photovoltaic assembly is generally the floor height transparent glass, and lower floor is glass or TPT plate, therebetween EVA film and solar battery sheet, adopt framework such as aluminium frame with this composite construction protection after, piece together ride over outdoor or building on as Blast Furnace Top Gas Recovery Turbine Unit (TRT).But this and the generation mode that combines of building be the simple appendix of photovoltaic product in architectural (BAPV form), rather than the photovoltaic product is integrated into architectural (BIPV form), becomes the part of building.
Chinese patent prospectus CN101232053 discloses a kind of craftwork double glass photovoltaic component and production method thereof, and this photovoltaic module comprises with understructure: bottom is an artistic glass; Top layer is a solar energy photovoltaic glass; The intermediate layer is two-layer EVA sealed Cellophane, accompany crystal silicon cell in the middle of this two-layer EVA sealed Cellophane, adopt two glass structures, excellent in cushion effect, good weatherability, but adsorption strength lower (approximately 5.15N/mm) does not reach building safety glass code requirement between EVA interlayer and the glass, is not suitable for going along with sb. to guard him of the building outside.
The CN1901236 method for producing solar cell assembly, from bottom to top with the superimposed vacuum laminator of putting into of glass/EVA/ solar cell array/EVA/TPT, adopt the vacuum layer platen press that the laminating machine lower chambers is vacuumized, pressurized, heated, glass/EVA/ solar battery string/EVA/TPT is hot-pressed onto together, install frame after the moulding additional, make solar module.But because of light tight can not be as glass curtain wall.
Except EVA, polyvinyl butyral resin (PVB) also is commonly used for the glass composite material, adopts the vacuum layer platen press to glass and composite material pressurized, heated, can make the lamination compound glass.But because PVB material character and EVA differences in materials are bigger, solar battery sheet is broken easily again, when solar battery sheet occurring in the composite bed, adopt the manufacture method of lamination compound glass, the perhaps manufacture method of the solar module of EVA interlayer, can not produce the available solar energy battery component because solar battery sheet is broken, therefore the domestic report of not seeing the PVB material as the solar module composite material.
Summary of the invention
The object of the present invention is to provide a kind of building safety glass code requirement that satisfies, can be used for building going along with sb. to guard him of the outside and comprise curtain wall, roofing, sunshade, door and window, guardrail, floor, promptly be used for the manufacture method of photovoltaic-building integrated solar photovoltaic module.
Manufacture method of the present invention in turn includes the following steps:
A. on the sheet glass of tiling, spread at least one layer of PVB film, then place the solar battery sheet of having finished electrical connection, spread one deck PVB film at least then, repave a sheet glass, become superimposed assembly;
B. superimposed assembly is loaded under its flat presentation in the flexible airbag, is decompressed to 0.05～0.15 crust in the flexible airbag, flexible airbag is decompressed to 0.5～0.9 crust outward, is heated to 130～135 ℃ simultaneously, constant temperature 5～20 minutes;
C. in the flexible airbag or flexible airbag be pressurized to 1.1～1.6 crust outward, 130～135 ℃ of following constant temperature 3～10 minutes, be cooled to below 50 ℃ by 3～6 ℃/minute speed, pressure release obtains solar photovoltaic assembly to normal pressure.
In above-mentioned steps A, be collected to lead end with the solder series, parallel between the solar battery sheet, stick with glue the correct position that sticks on the PVB film after agent or the localized heating, the solar battery sheet position is fixed, avoid the battery sheet in the building-up process of assembly, to occur moving and influencing attractive in appearance.
After above-mentioned steps B finishes, can be directly in the flexible airbag or flexible airbag pressurize the operation of implementation step C outward.But preferably, superimposed assembly is cooled to room temperature, removes the inside and outside negative pressure of flexible airbag, take out airbag, can carry out post bake to the PVB material like this, further improve the sticking effect of PVB material and glass.
In above-mentioned steps B, the preferred pressure of decompression is 0.08～0.12 crust in the flexible airbag, and heating-up temperature is preferably 132 ± 1 ℃.
In above-mentioned steps C, in the flexible airbag or flexible airbag external pressure 1.2～1.4 crust preferably, heating-up temperature is preferably 132 ± 1 ℃.
The present invention adopts the air in the airbag vacuum eliminating assembly, select melt temperature to make the PVB film have suitable flowability, utilize the deadweight of air pressure and glass with the gentle pressing of assembly, avoided the fragmentation of solar battery sheet, obtain high rate of finished products, satisfied the rate of finished products requirement that solar photovoltaic assembly is made.The finished product of producing " the two glass photovoltaic modulies of PVB " has stronger peel strength, do not need frame to be reinforced, satisfy the shock resistance and the security performance of building safety glass, the curtain walls, roofing, sunshade, door and window etc. that can be directly installed on building have the position of requirement to safety, realize photovoltaic-architecture-integral (BIPV).
