Problems solved by technology

Due to the glass-free and frameless structure of the existing flexible photovoltaic modules, during use, external water vapor can enter the power generation part inside the module along various paths such as the front, back and edge parts of the flexible photovoltaic module, causing battery attenuation , film aging and other problems, which lead to the attenuation of photoelectric conversion efficiency of flexible photovoltaic modules, a significant drop in power generation, and a significant reduction in the service life of modules
[0005] It can be seen that the water permeability of existing flexible photovoltaic modules is relatively high, resulting in unsatisfactory performance

Abstract

The invention provides a low-water-permeability flexible photovoltaic module which comprises a weather-proof layer, at least one first packaging adhesive film layer, a solar cell unit, at least one second packaging adhesive film layer, a flexible insulating layer, at least one third packaging adhesive film layer and a back plate layer which are sequentially stacked. A water-blocking adhesive tape is pasted around the side edges of the weather-proof layer, the first packaging adhesive film layer, the solar cell unit, the second packaging adhesive film layer, the flexible insulating layer, the third packaging adhesive film layer and the back plate layer. The invention further provides a preparation method of the low-water-permeability flexible photovoltaic module. The front surface, the back surface and the side surfaces of the low-water-permeability flexible photovoltaic module can block water vapor, and the low-water-permeability flexible photovoltaic module has ultrahigh water-blocking performance, so that the service life of the flexible photovoltaic module can be effectively prolonged, the attenuation of photoelectric conversion efficiency can be reduced, and the cost per kilowatt hour can be reduced.

Description

technical field [0001] The invention relates to the related technical field of photovoltaic power generation technology, and more precisely relates to a flexible photovoltaic module with low water permeability and a preparation method thereof. Background technique [0002] Under the general environment of energy saving and emission reduction, fields such as photovoltaic building integration and portable solar mobile energy have become key development areas of the photovoltaic industry. With the continuous development of these fields, it is increasingly difficult for traditional photovoltaic modules to meet the requirements of customization, weight, and ease of installation. The flexible photovoltaic module can meet the above requirements and has a good application prospect in this field. [0003] Flexible photovoltaic modules use a transparent front sheet to replace the glass layer, and a flexible back sheet on the back, generally without a frame, which has the advantages o...
