In 2026, the photovoltaic auxiliary‑materials segment continues to evolve, with high‑performance PVB interlayers—boasting superior aging resistance, yellowing resistance, and high light transmittance—seeing steadily increasing adoption in bifacial PV modules, outdoor photovoltaic curtain walls, and distributed‑generation applications. These materials are gradually becoming the cornerstone of PV encapsulation, reshaping the long‑standing market dynamics dominated by EVA films.
Compared with conventional encapsulant films, the newly upgraded photovoltaic‑specific PVB interlayer boasts a light transmittance exceeding 90%, while delivering robust UV resistance, high‑temperature tolerance, and superior resistance to damp‑heat aging. It is well suited to demanding outdoor operating conditions—such as deserts, coastal regions, and environments characterized by high temperature and high humidity—significantly extending the service life of photovoltaic modules and reducing power‑output degradation. In response to industry trends toward lighter‑weight, higher‑power modules, the material formulation has been refined to maintain strong adhesion and impact resistance while achieving a thinner, lighter profile, thereby seamlessly supporting the manufacturing processes of next‑generation large‑format photovoltaic modules.
Industry data analysis indicates that the global PVB interlayer film market has maintained steady growth, with the photovoltaic sector emerging as a key downstream application—second only to the automotive industry—in terms of rapid expansion. As the PV industry places increasingly stringent demands on module stability and long-term power-generation performance, customized PVB interlayers tailored to photovoltaic applications will continue to come online, serving as a new core driver of industry growth.
