- Silane Chemistry: The additive makes use of chemistry that is based on silane, which enables strong chemical bonding to occur between the EVA film and the other components of the PV module. This guarantees that there is excellent adhesion, which in turn improves the mechanical integrity of the module and increases its longevity.
- Enhancement of Crosslinking: The product improves the crosslinking process of the EVA film during the lamination process, which ultimately leads to enhanced module encapsulation. The module’s resistance to external conditions such as temperature fluctuations, humidity, and exposure to ultraviolet light is improved as a result of its characteristics.
- Moisture Barrier: The additive has the ability to create an efficient moisture barrier within the EVA layer, which in turn reduces the likelihood of moisture penetration and the possibility of module degradation. The long-term durability and performance of the module are both improved as a result of this feature.
- Optical Transparency: The Silane Functional Additive helps to preserve the optical transparency of the EVA film, which will ensure that there is a minimum influence on the amount of light that is transmitted to the solar cells. With this feature, the PV module’s energy conversion efficiency is increased to its maximum potential.
Vantaggio
The silane-based chemistry of the additive helps to promote strong adhesive between the EVA film and the encapsulant, backsheet, and other module components. This is referred to as enhanced adhesion. Through this enhanced adhesion, the module’s integrity is maintained over the long term, hence lowering the likelihood of delamination and the accompanying decline in performance.
Improved Crosslinking: The additive improves the efficiency of the crosslinking process that occurs during module lamination, which ultimately results in an encapsulating layer that is more robust and long-lasting. The module’s resilience to environmental stressors, such as temperature cycling and exposure to moisture, is improved as a result of this greater crosslinking.
Resistance to Moisture: The Silane Functional Additive is able to effectively lower the permeability of the EVA film to moisture, which in turn minimises the danger of moisture-related concerns such as corrosion, electrical deterioration, and potential safety hazards. The reliability of the module is improved, and its operating lifespan is increased, as a result of this feature.
Optimal Optical Properties: The additive helps to preserve the high optical transparency of the EVA film, which in turn ensures that the solar cells receive an adequate amount of light. The energy conversion efficiency of the module is maximised as a result of this characteristic, which leads to an increase in power output and an improvement in the overall performance of the system.

Applicazione
The Silane Functional Additive for Photovoltaic EVA Film was developed with the express purpose of being utilised in the manufacturing processes of PV modules, which include the following:
Formulation of EVA Film: During the production process, it is incorporated into the formulation of EVA film, which ensures that it is dispersed and integrated inside the film matrix in a consistent manner.
b. Encapsulation of Modules: The additive improves the adhesion between the EVA film and the encapsulant, which results in a dependable encapsulation and safeguards the solar cells against the effects of the surrounding environment.
c. Lamination: It is appropriate for use in a variety of module lamination procedures, specifically those that facilitate the bonding between the EVA film and the backsheet material. This ensures that the module construction is both secure and long-lasting.
d. Applications of Bifacial Modules: The Silane Functional Additive is also compatible with bifacial module designs, which are characterised by the fact that both the front and back sides of the module generate electricity. Because of its increased optical transparency, the rear side power generation is able to benefit from the increased amount of light that is able to reach the back cells.
