Example Embodiment
[0043] Example 1
[0044] See Figure 1-5, the preparation process is as follows:
[0045] 1) Prepare a composite layer of cloth 1 and polymer film 2 on a laminator, and control the temperature to melt the polymer film.
[0046] 2) Cut the part of the upper cloth or cloth / polymer film composite layer corresponding to the light-receiving part of the unit cell to remove the holes 3 (see Figure 1); if the upper layer only has the polymer film, there is no need to cut the holes.
[0047] 3) Holes 6 are punched in the fluoroplastic film 5 around the unit cell sheet 4 that has been encapsulated with a fluoroplastic film (see Figure 2).
[0048] 4) Connect each unit cell with a wire; the wire connection is sealed and protected with epoxy resin (ie, A / B glue).
[0049] 5) Stack the lower layer (cloth, polymer film or polymer film / cloth composite layer) on the laminator in a predetermined order from bottom to top, 7, the unit cell 4 and the upper layer (cloth, polymer film or Cloth / polymer ...
Example Embodiment
[0054] Example 2
[0055] The preparation process is similar to that of Example 1. In Example 2, referring to Figure 5, a polyester cloth (500g / cm 2 ) 1 and EVA film (containing 15% VA, cross-linking degree of 85%, thickness of 0.2mm, transparent, fast curing type) 2 at 100 ℃, laminated for 3 minutes to make a composite layer in advance. Cut half of the composite layer at the light-receiving position of the corresponding unit cell in the polyester cloth / EVA film composite layer to form a cavity 3 to be used as the upper layer; the other half of the polyester cloth 72 / EVA film 71 composite layer is reserved as the lower layer . The fluoroplastic film 5 around the unit cell sheet 4 that has been encapsulated with the ETFE film is punched with round holes 6. Connect each unit cell 4 in the assembly with a rectangular copper wire, and seal and protect the wire connection with epoxy resin (ie, A / B glue). Stack the materials from bottom to top in the following order: polyester cloth / EVA...
Example Embodiment
[0056] Example 3
[0057] The preparation process is similar to that of Example 1. In Example 3, the nylon cloth (1000g / cm 2 ) And EVA film (containing 20% VA, 90% cross-linking degree, 0.5mm thick, semi-transparent, fast curing type) at 90°C, laminated for 5 minutes to make a composite layer in advance. Cut the composite layer of the light-receiving position of the corresponding unit cell in the nylon cloth / EVA film composite layer. Punch holes in the fluoroplastic film around the unit cell sheet that has been encapsulated with F30 film. The unit cells in the assembly are properly connected with rectangular copper wires, and the connection of the wires is sealed and protected with epoxy resin (ie, A / B glue). Stack the materials from bottom to top in the following order: nylon cloth / EVA film composite layer-unit cell sheet-nylon cloth. Stick the light-receiving part of the unit cell with adhesive tape. Place a stainless steel wire with a diameter of 3mm at the place to be folded...
