Embodiment 1
[0058] Such as Figure 8 and Figure 9 As shown, in the implementation of the present invention, a packaging structure of a flexible solar thin film battery, the packaging structure is a rectangle, including a protective film, a structural film, a CIGS battery unit and a back film pressed from top to bottom. Usually, for convenience Processing, CIGS battery cells are generally made into rectangles, and the core object of packaging is CIGS battery cells, so the packaging structure is rectangular. The size of the structural film and the CIGS battery unit is the same; the size of the back film is larger than that of the CIGS battery unit; the protective film includes a main body and a side, the main body is the same size as the CIGS unit, and the side parts are arranged on the four sides of the main body and are integrated with the main body. The top seal tightly covers the structural membrane and the sides of the CIGS cell and is compressed against the backing membrane. In the...
Embodiment 2
[0093] Such as Figure 10 As shown, a packaging tooling of a flexible solar thin film battery packaging structure, the packaging tooling is used to process the packaging structure in Example 1; the packaging tooling includes a first tooling and a second tooling, and the first tooling and the second tooling are equipped with at least one A set of parallel surfaces, one of which is flat, and the other is provided with a square groove; the size of the groove of the first tooling is equal to the size of the EEA film, EVA glue and CIGS battery unit of the packaging structure; the groove of the second tooling The size of is equal to the overall size of the package structure. The encapsulation structure in Example 1 is equivalent to using a protective film and a back film to wrap the structural film and the CIGS battery unit. In the embodiment of the present invention: the first tooling is used to complete the lamination of the structural membrane and the CIGS battery unit, which on...
Embodiment 3
[0097] A packaging method for a flexible solar thin film battery, the packaging method uses the packaging tooling in Example 2 to package the flexible solar thin film battery, and makes the packaging structure in Example 1;
[0098] The packaging method is as follows:
[0099] S1. Processing CIGS battery unit. The size of CIGS battery unit should be determined according to the design size, which is a preset parameter. Similarly, the size of ETFE film, POE glue, EEA film, EVA glue and PVB glue is also a preset parameter, which needs to be determined according to It should be determined according to the processing target. It should be noted that the length of the side of the ETFE film is greater than the thickness of the solar thin film battery. Partially fully bonded to the DNP membrane;
[0100] S2. Place the groove of the first tooling upwards, and place the EEA film, EVA glue and CIGS battery unit in sequence in the groove. When putting in each material, all materials need to...
