Background

The flexible solar cell has the characteristics of light weight, thin thickness and flexibility, and part of the flexible solar cells have the advantages of low cost and high efficiency at the same time, thereby having great advantages in the field of aerospace. However, while the flexible solar cell has a certain flexibility, the cell unit layer may be damaged due to stress concentration such as excessive bending during use or installation, so that the cell module is partially failed, and the reliability of the flexible solar cell module is reduced. Therefore, the flexible solar cell module needs to be packaged, and the formed packaging structure not only can play a good role in protecting and supporting the cell module layer, but also can increase the overall flexibility of the solar cell module.

The existing flexible solar cell module packaging structure is mainly a flexible solar cell module packaging structure supported by aramid fiber, the flexible solar cell module supported by the aramid fiber comprises a flexible solar cell module layer and a packaging layer, an aramid fiber layer is arranged between the flexible solar cell module layer and the packaging layer, the aramid fiber has a hole structure and has certain thickness, and is a good heat insulation material, and the aramid fiber layer is bonded with the aramid fiber layer through a bonding layer. Although this packaging structure can play better protection and supporting role to the battery pack layer, can also increase solar module's whole flexibility, but the packaging layer does not set up open pore structure, and the holding can't communicate with each other with the external world after the encapsulation at the downthehole air of aramid fiber, and the heat that produces at flexible solar module during operation causes this part very easily by the air inflation of encapsulation, and then leads to flexible solar module to swell, and it is bad with flexible solar module's battery piece drum when serious.

In summary, there is a need for a packaging structure of a flexible solar cell module to solve the problem of the prior art that the air packaged in the packaging structure cannot be released to cause the damage of the cell.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a flexible solar module's packaging structure, concrete technical scheme is as follows:
