- High PID Resistance: The additive provides a strong barrier against Potential Induced Degradation (PID), a serious issue in PV modules caused by large voltage differentials. It reduces the effects of PID while preserving the efficiency and performance of solar panels over time.
- Improved Adhesion: The epoxy group functionalization improves the additive’s adhesive qualities, resulting in strong bonding between the EVA encapsulant and other layers within the PV module. This enhanced adhesion improves the module’s structural integrity.
- UV Resistance: The additive has good UV resistance, shielding the EVA encapsulant and PV cells from the negative effects of prolonged exposure to sunlight. UV stability ensures the PV module’s lifetime and durability.
- Thermal Stability: The additive’s characteristics and effectiveness remain unchanged even at high temperatures. This stability is critical for PV modules that operate under a variety of environmental situations.
- Low Volatility: The additive is low in volatility, reducing the possibility of outgassing while maintaining a stable encapsulation environment within the PV module. This feature improves the dependability and safety of the solar panel.
Advantage
The Epoxy Group Functionalized EVA Photovoltaic Film Anti-PID Additive has several advantages, including improved module efficiency. By minimising PID impacts, the additive helps to preserve PV module efficiency, assuring optimal energy generation throughout the module’s lifespan.
Extended Module Lifespan: The additive’s PID resistance and UV stability help PV modules last longer. This endurance lowers maintenance costs while increasing the return on investment for solar installations.
Improved Reliability: The additive’s excellent adhesion and heat stability increase the reliability of PV modules, lowering the danger of delamination, cracking, and performance deterioration.
Cost-Effectiveness: By protecting against PID and UV deterioration, the additive decreases the need for premature module replacements and repairs, saving solar system owners money.
Environmental Compatibility: The additive is designed to be environmentally benign, having little influence on the ecosystem. It adheres to severe environmental legislation and sustainability norms.

Application
Typical application
Used to improve the anti-PID performance of photovoltaic adhesive film
EVA Encapsulant Formulations: The additive can be mixed directly into EVA encapsulant formulations during the PV module production process.
Pre-Applied EVA Sheets: Manufacturers can provide pre-applied EVA sheets that already contain the additive. These sheets make it easier for solar panel producers to assemble modules while also providing consistent and effective PID protection.
The recommended addition amount is 2 to 5%.
It is best to use a combination of:
1-RM210A: 1% + R2320: 4%.
2-RM208: 2% + R2320: 3%.
Application Industry
Epoxy Group Functionalized EVA Photovoltaic Film Anti-PID Additive has industry applications in solar energy systems. The additive was developed specifically for use in PV modules and solar energy systems. It is compatible with both crystalline silicon and thin-film PV systems.
Commercial and residential solar installations: Solar panel manufacturers and installers can use the additive into their EVA encapsulant formulas to increase the dependability and efficiency of solar panels used in commercial and residential settings.
Utility-Scale Solar Farms: The addition improves PID resistance and UV stability, which benefits large-scale solar farms. It ensures steady energy generation while reducing maintenance requirements for utility-scale systems.
Off-Grid Applications: The additive is perfect for off-grid solar applications including remote power systems and solar-powered telecommunications devices. It offers consistent energy generation in difficult circumstances.
BIPV (Building Integrated Photovoltaics): Architects and building developers can employ PV modules with the additive in BIPV applications, which incorporate solar panels into building facades and rooftops. The PID resistance and increased lifespan improve the building’s sustainability and beauty.
