Currently, the photovoltaic (PV) industry is in a structural adjustment phase driven by overcapacity, with accelerating industry consolidation. However, long-term demand remains optimistic. Going forward, technological innovation and cost control will continue to drive the expansion of diversified application scenarios.
First-generation EVA encapsulant films have long dominated the market due to their mature manufacturing processes and low costs. Nevertheless, their limitations in weather resistance and resistance to potential-induced degradation (PID) have spurred the industry to pursue superior alternative solutions. POE encapsulation materials, boasting excellent water vapor barrier properties and high electrical resistivity, have become the material of choice for high-efficiency technical routes such as double-glass modules and N-type cells, significantly enhancing the long-term reliability of PV modules. Co-extruded POE/EVA encapsulant films combine the merits of both materials, striking a favorable balance between performance and cost, and are gaining growing popularity among manufacturers.
In terms of specific products, SABIC’s FORTIFY™ PV POE encapsulant film features high volume resistivity that maintains low leakage current, delivering long-term protection for photovoltaic modules. SABIC® PP 95MK40T PV backsheet material offers selective barrier properties against water vapor, oxygen, and acetic acid.
Wanhua Chemical has developed a comprehensive suite of solutions to empower the new energy industry to pursue higher efficiency and unlock broader application scenarios. Among these, POE stands out as a flagship product. PV encapsulant films made from Wanhua’s POE deliver high water vapor transmission resistance, exceptional weatherability, excellent transparency, and strong PID resistance, effectively boosting module power generation efficiency and reliability while extending service life.
