Method for packaging and producing BIPV assembly by using PVB

Abstract

The invention discloses a method for packaging and producing a BIPV assembly by using PVB. The BIPV assembly packaging method comprises the specific steps of laying a lower-layer hot-melt adhesive film on clean lower-layer toughened glass; welding battery pieces: welding the battery pieces into battery strings by adopting welding strips; laying the battery strings on the lower-layer hot-melt adhesive film, and welding the battery strings by adopting bus bars; using a small PVB block, a first PVB bonding strip and a second PVB bonding strip to form a middle anti-bubble bonding structure; layingan upper-layer hot-melt adhesive film, and laying upper-layer toughened glass on the upper-layer hot-melt adhesive film; sleeving a first PVB bonding frame body outside the edge of the laid assembly;putting the laid assembly into a laminating machine; putting the laminated assembly into a heating packaging device for curing packaging; and independently putting the packaged BIPV assembly into a dehumidifying room. According to the method, the high-pressure kettle process is omitted, and the secondary air pressure operation is not needed, so that the production time is greatly shortened and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of solar cell panel assembly manufacturing, in particular to a method for producing BIPV assemblies by encapsulating PVB. Background technique [0002] Building Integrated Photovoltaics (BIPV) technology integrates photovoltaic modules on buildings, so that they not only have the function of generating electricity, but also can be used as building materials at the same time. This technology replaces building roofs, exterior walls, windows, fences, etc. with photovoltaic modules, which can be used as building materials and generate electricity. It truly realizes the characteristics of low-carbon, energy-saving, and environmental protection in modern buildings. , thermal comfort, lighting, sound insulation and other architectural requirements, have been widely used. [0003] Building Integrated Photovoltaics (BIPV) is the integration of photovoltaics and buildings, and it is also one of the important applicat...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to provide a method for producing BIPV components with PVB encapsulation, so as to solve the problems of empty glue, air bubbles, edge degumming, unmelted PVB and the like after BIPV components are laminated and require a secondary layer pressure, and the need to enter the autoclave for air pressure, which increases the production cost and time, in order to reduce the possibility of empty glue, air bubbles, edge degumming, and unmelted PVB in some components during the lamination process, and ensure the production of BIPV components quality, reduce production time, reduce production cost
