The barrier film 7 is a material having high light transmittance, high water resistance, and strong gas barrier properties, and is a multilayer structure film formed by simultaneously extruding a material having a strong gas barrier property and a polyolefin having a high heat sealing property and a high moisture barrier property. The material of the barrier film 7 is selected from, but not limited to, nano-inorganic materials contained modified PVA (polyvinyl alcohol) coating film, PVDC (polyvinylidene chloride) coating film, ethylene/ vinyl alcohol copolymer film or silicon oxide coating film.
The manufacturing method of the PV building material 100 (for example, rigid PV building material) is as follows:
Step 1 Prepare the solar cell module. The preparation of the solar cell module includes arrangement of the sub-units of the solar cell module; connection of the sub-units in series or in parallel; convergence; and leading out of the wires.
Step 2 Prepare the materials for the building material body, the insulating barrier layer and the front film layer, and cut the materials for the building material body, the first insulating barrier layer, the second insulating barrier layer and the front film layer according to predetermined sizes to obtain the building material body, the first insulating barrier layer, the second insulating barrier layer and the front film layer.
Step 3 Stack the building material body, the first insulating barrier layer, the solar cell module, the second insulating barrier layer and the front film layer sequentially to form a stacked structure; and perform the encapsulation and combination on the above mentioned stacked structure with the rolling/laminating/heating pressuring process or any similar encapsulation process.
Step 4 Mount the junction box, and connect the junction box to the solar cell module using wires based on the wiring connection method.
The laying method of the PV building material 100 (for example, flexible rolling material) is as follows:
Step 1 Prepare the mounting surface (the surface of the building where the building materials are to be laid), for example, including cleaning, positioning, etc. on the construction base surface of the building;
Step 2 Install the PV building materials, including firstly affixing one end of the PV building material onto the mounting surface, and then applying a certain pressure (predetermined pressure) so that this one end of the PV building material is in close contact with the mounting surface, and next applying pressure from the center of the PV building material to the edges of the same until the entire PV building material is completely fitted onto the mounting surface.
Step 3 Use a suitable tool (such as a wood or silicone pressure roller) to uniformly roll on the laid PV building material from the center of the PV building material to the edges of the same so that the PV building material is in close contact with the mounting surface and securely firmly laid on the mounting surface.
In the case of laying multiple PV building materials by means of lap bonding, the hot air welding method, hot melt method, self-adhesive method, mechanical fixing method, etc. may be used for the connection of multiple PV building materials.
For flexible rolling materials with both the PV power generation function and the building water resistant (building material) function, if filling or cutting is required at the corner of the PV building material, the same building material may be used for the filling and cutting, and the above lap bonding method may be adopted for the lap of the laid flexible rolling material to ensure the overall water resistant performance. For rigid PV building materials, the above connecting device may be used to connect the PV building materials.
