Flexible assembly with stainless steel mesh packaging structure
View Patent ↗A flexible assembly with a stainless steel mesh packaging structure includes a flexible back plate, a first hot melt adhesive, a solar cell string, a stainless steel mesh, a second hot melt adhesive, and a flexible front plate. The flexible back plate and the flexible front plate are respectively arranged on the outer surface of the first hot melt adhesive and the outer surface of the second hot melt adhesive, and the solar cell string and the stainless steel mesh are arranged between the first hot melt adhesive and the second hot melt adhesive. The stainless steel mesh is arranged at partial or all positions around the outer edge of the solar cell string and is continuously distributed or separately distributed. The stainless steel mesh is arranged around the solar cell string to further strengthen the strength of the flexible assembly and improve the tearing resistance of the flexible assembly.
1. A flexible assembly with a stainless steel mesh packaging structure, comprising a flexible back plate, a first hot melt adhesive, a solar cell string, a stainless steel mesh, a second hot melt adhesive, and a flexible front plate, wherein the flexible back plate and the flexible front plate are respectively arranged on an outer surface of the first hot melt adhesive and an outer surface of the second hot melt adhesive, the solar cell string and the stainless steel mesh are arranged between the first hot melt adhesive and the second hot melt adhesive, wherein the solar cell string is in direct physical contact with the first hot melt adhesive and the second hot melt adhesive, and the stainless steel mesh is also in direct physical contact with the first hot melt adhesive and the second hot melt adhesive; the stainless steel mesh is arranged at partial or all positions around an outer edge of the solar cell string, and the stainless steel mesh is continuously distributed or separately distributed.
2. The flexible assembly with the stainless steel mesh packaging structure according to claim 1 , wherein the stainless steel mesh is made of stainless steel mesh materials; the stainless steel mesh is of at least one type of a stainless steel plain mesh, a stainless steel twill mesh, a stainless steel bamboo pattern mesh, a five heddle stainless steel mesh, a stainless steel punching hole mesh, and a stainless steel chain link mesh; a mesh number of the stainless steel mesh is less than 20, 20, 30, 40, 60, 80, or more than 80; a width of the stainless steel mesh and a length of the stainless steel mesh are adjusted and designed according to a size of a solar cell assembly and installation requirements of the solar cell assembly.
