Abstract
The weatherability of photovoltaic (PV) modules directly affects their long-term stability and power generation efficiency, especially under extreme climatic conditions. As the core protective layer of PV modules, the weatherability of encapsulation materials is a key factor determining their service life. To improve the weather resistance of PV modules, this paper discusses recent advances in modified encapsulation materials, including technologies for enhancing UV resistance, moisture-heat resistance, oxidation resistance, and corrosion resistance of PV encapsulants. By optimizing the chemical composition of encapsulation materials and employing advanced composite materials and surface treatment technologies, the ability of PV modules to withstand environmental degradation can be significantly improved, thereby extending their operational lifespan. This research provides a theoretical basis and practical reference for upgrading encapsulation material technologies within the photovoltaic industry.
