[0002] As a clean and renewable energy source, the photovoltaic industry has received widespread attention and rapid development worldwide in recent years. Photovoltaic modules are an important part of the photovoltaic system, and the selection of their frame materials is crucial to the performance and life of the entire system. At present, the frames used in most photovoltaic modules are aluminum alloy frames. During the use of photovoltaic modules, metal photovoltaic frames have problems such as poor anti-PID performance, high cost, and poor corrosion resistance in high salt fog environments. Due to the strength characteristics of polymer materials, polymer composite frames have not been accepted by mainstream module manufacturers, and their application scenarios are limited. The PID effect refers to the power drop problem caused by water vapor penetration and decomposition inside the module; the direct result of this process is a reduction in the power output of the module.
