Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a flexible frame and a flexible photovoltaic component. Background Art

[0002] The structure of the photovoltaic module is simple, mainly including glass, upper and lower EVA adhesive layers, battery cells, backboards and other materials. The materials are laminated into a whole and then encapsulated with an aluminum alloy frame. The aluminum alloy frame is inelastic and can easily cause the module to break in places with large temperature differences between day and night. For example, Chinese patent application announcement number CN217590726U, application date June 16, 2022, discloses a highly stable flexible photovoltaic module frame, including an L-shaped fixing and a frame assembly, a pair of the L-shaped fixings are arranged side by side and extend laterally, one side limb of the two is located in the same plane and faces the direction of the adjacent L-shaped fixing, and the other side limbs are all facing upward, and multiple frame assemblies are arranged side by side between a pair of L-shaped fixings, and the two ends of the frame assembly are respectively connected to the limbs of a pair of L-shaped fixings located in the same plane, and an installation groove for installing a flexible photovoltaic module is formed between the two adjacent frame assemblies and the L-shaped fixings connected thereto, and a connection hole is also provided on the limb connecting the L-shaped fixing and the frame assembly.

[0003] Currently, flexible solar photovoltaic modules use a transparent front panel and a white back panel made of PET. For example, Chinese patent application publication number CN217671607U, filed on July 18, 2022, discloses a flexible photovoltaic module comprising, from bottom to top, a back panel layer, a first adhesive film layer, a cell string layer, a second adhesive film layer, a PET film substrate, a third adhesive film layer, and a flexible transparent front panel. The layers are connected together through a lamination process. The high water permeability of the PET substrate can lead to limited reliability of the flexible module.

[0004] When flexible components are placed in different environments for a long time, such as high temperature and high humidity, coastal areas, windy and sandy areas, etc., the flexible components are easily affected by the environment and may experience delamination, damage, breakage, etc. Utility Model Content
