Embodiment 1

[0017] 1. Material pre-treatment: Cut 1350mm×750mm×6mm high-transmittance glass and ordinary glass, finely grind straight edges around, clean and dry, then toughen, then use purified water and glass cleaning agent for secondary cleaning and drying. Clean the surface of 125mm×125mm solar cells, and weld them into 9×4 battery strings according to the designed series-parallel method by soldering. Cut the PVB film with a thickness of 0.76mm into 1370mm×770mm.

[0018] 2. Laminated glass assembly: Spread a piece of PVB film on the above ordinary glass, then place the above strings of solar cells, adjust the local position to make it as neat as possible, and then use an electric soldering iron at 80±2°C to heat the solar cells. The cells are pasted on the PVB film one by one, covered with a PVB film, and finally laminated with high-transmittance glass.

[0019] 3. Lamination molding: Put the above-mentioned laminated components on a flexible air bag in a flat state, and place it in...

Embodiment 2

[0024] 1. Using the same material pretreatment and laminating glass assembly method as in Example 1 to obtain a laminated assembly.

[0025] 2. Lamination molding: Put the above-mentioned laminated components into a flexible air bag in a flat state, and place it in a container. The air bag is connected to a vacuum pump to reduce the pressure to 0.1 bar, and the container is connected to the vacuum pump to reduce the pressure to 0.7 bar. At the same time, the container is heated to 132±1°C, and after 10 minutes of constant temperature, it is cooled to room temperature, and the negative pressure is removed to take out the air bag.

[0026] 3. Pressurize the container to 1.4 bar, keep the temperature for 5 minutes, cool down to 45°C at a rate of 4°C / min, release the pressure to normal pressure, take out the components, trim the edges, lead the electrodes, and do waterproof treatment to obtain PVB double-glass photovoltaics Finished components.

Abstract

The invention discloses a fabrication method of a building integrated photovoltaics solar photovoltaic module. The fabrication method comprises the following steps: folding and putting glass sheet-PVB film-solar cell-PVB film-glass sheet in a flexible air bag, depressuizing the gas bag, pressurizing the outside of the folded module after heating, and cooling slowly to obtain the solar photovoltaic module. In the fabrication method, air in the module is removed by vacuumizing the air bag, a fusion temperature is selected to cause the PVB film to have proper fluidity, the module is moderately pressed by virtue of atmospheric pressure and dead weight of the glass to prevent the solar cell from breakage and obtain higher yield, and an obtained product meets the requirements of the building safety glass specification and can be used in enclosures of a building including curtain walls, roofs, sunshades, doors, windows, guard fences and floors, thus realizing the building integrated photovoltaics.

Description

technical field [0001] The invention relates to a manufacturing method of a solar power generation device, in particular to a manufacturing method of a solar photovoltaic module used for photovoltaic-building integration. Background technique [0002] Existing solar photovoltaic modules are generally made of high light-transmitting glass on the upper layer, glass or TPT board on the lower layer, EVA film and solar cells in the middle, and the composite structure is protected by aluminum frames and other frames, and then assembled outdoors or in buildings. as a power generating device. But this way of power generation combined with buildings is just that photovoltaic products are simply attached to the building (BAPV form), rather than photovoltaic products integrated into the building (BIPV form) and become an integral part of the building. [0003] Chinese patent publication CN101232053 discloses a process double-glass photovoltaic module and its production method. The pho...
