Photovoltaic Grade PVB Interlayer Film Manufacturers

PVB Film for Glass Glass Solar Panels has excellent adhesion and weather resistance

In the rapidly evolving field of renewable energy, solar panels have become a cornerstone of sustainable power generation. Among the various technologies driving innovation in photovoltaic (PV) systems, PVB (Polyvinyl Butyral) film for glass-glass solar panels has emerged as a critical component that enhances both performance and durability. Jiangsu Aotianli New Materials Co., Ltd. (ATL), a leading manufacturer in high-performance PVB interlayer films, plays a pivotal role in advancing this technology.

Established in 2014 and headquartered in Wuxi, Jiangsu Province, ATL specializes in the research, development, production, and sales of high-performance PVB interlayer films. With advanced manufacturing processes, continuous technological innovation, and a comprehensive supply chain strategy, ATL has established itself as a key player in both domestic and international markets. Through strategic acquisitions such as Jiangxi Tianhui New Materials Co., ATL has built a complete industrial chain—from PVB resin to finished intermediate films—ensuring stable raw material supply and superior product quality.

The Role of PVB Film in Glass-Glass Solar Panels
PVB Film for Glass Glass Solar Panels are increasingly preferred over traditional glass-backsheet modules due to their enhanced durability and efficiency. In these double-glass modules, PVB film serves as an encapsulant that bonds two layers of tempered glass around the solar cells. Compared to other encapsulation materials like EVA (ethylene vinyl acetate), PVB film for glass-glass solar panels offers superior mechanical strength, optical clarity, and long-term stability , making it ideal for demanding environmental conditions.

One of the standout features of PVB film is its excellent adhesion properties . It forms a strong bond with glass surfaces, which is essential for maintaining structural integrity under mechanical stress or extreme weather. This robust adhesion ensures that the solar cells remain securely sealed within the panel, protecting them from moisture, dust, and physical damage. As a result, PVB-encapsulated glass-glass solar panels exhibit significantly lower rates of delamination and degradation over time.

Moreover, weather resistance is another key advantage of using PVB film for glass-glass solar panels. Traditional EVA-based encapsulants can yellow or degrade under prolonged UV exposure, reducing light transmittance and overall module efficiency. In contrast, PVB film demonstrates excellent UV resistance and maintains high transparency even after years of outdoor use. This makes it particularly suitable for applications in harsh climates, including coastal areas, deserts, and high-altitude regions where solar installations are often deployed.
