CAPSSUN, a PV encapsulant film manufacturer, put forth its multiple range of encapsulation film solutions, targeting global PV module makers
The company has recently developed an anti-acid EVA variant
Its POE, featuring anti-slip property, mitigates cell slippage, a common production defect, typically during TOPCon or PERC module lamination processes, says the company
With the evolving global landscape of PV technology, along with cost pressure, there has been an increasing demand for upgraded, cost-effective encapsulation solutions that provide cushion to the underlying thin cell matrix, as well as ensure the long-term durability of PV modules against environmental stressors.
CAPSSUN Plastic Insulation and Chemical Industry Inc. promoted Made-in-Türkiye encapsulation products at its stall at Intersolar Europe 2025. Intrigued by this Türkiye-based PV encapsulant film manufacturer that produces 3 different types of products, including EVA, POE, and EPE, Shravan Chunduri, Head of Technology at TaiyangNews, approached the company’s Manufacturing Engineer, Kaan Talu. During the conversation, Talu provided a brief overview of CAPSSUN’s encapsulant portfolio.
EVA, the primary encapsulant choice of conventional PV module makers, is available in the company’s product offers. This PV material, featuring high transmittance, probably the front side variant, can ensure the required incidence of sun irradiance over the underlying cell matrix, says the company’s website. Thanks to good crosslinking capability following the lamination process, its EVA exhibits good adhesion between glass and metallization components, resulting in high reliability and durability of PV modules. Notably, concerning the potential reliability hazards stemming from the crosslinked EVA’s acetic acid formation, following long-term field operation, the company has developed an anti-acid EVA variant, said Talu.
The company’s POE type encapsulant, with its patented formulation and production processes, exhibits anti-slip properties that prevent cell slippage defects, typically during TOPCon or PERC module lamination processes. Alongside supporting quality production, its POE offers both anti-PID property and resilience against module yellowing degradation. Moreover, with its low water vapor permeability rate, the PV module exhibits high resistance against water or moisture ingression in humid field operating conditions, ensuring the long-term lifecycle of the end product.
Offering a durable and cost-effective encapsulation film, the company developed its EPE film, which was promoted at the company’s booth. With a structure that consists of a thin POE layer sandwiched between 2 EVA layers, CAPSSUN’s EPE offers an amalgamation of the best properties of 2 different types of materials, as mentioned by the company. While the middle POE layer acts as a good water vapor barrier and enhances anti-PID performance, the outer EVA layers exhibit requisite adhesion to glass and PV cells of the underlying PV module.
Samples of all the above-mentioned encapsulation films were showcased at the company’s booth.
