Solutions to Mitigate UV-Induced Degradation
- Low UV Transmission Module Glass and Encapsulants:
- Using glass with lower UV transmission can effectively reduce the amount of UV radiation reaching the cells.
- Encapsulant materials can be designed to block UV radiation, preventing it from damaging the cells.
- UV-Mitigating Encapsulants:
- Technologies like the “Raybo” light conversion film (LCF) from Cybrid Technologies absorb UV photons and emit less damaging blue light, enhancing cell durability.
- This approach has been adopted by manufacturers like Huasun for their heterojunction technology (HJT) modules.
- Cell Design Improvements:
- Enhancing the passivation layers within the solar cells can reduce the impact of UV radiation. This includes optimizing the thickness and uniformity of these layers.
- Manufacturers like Trina focus on precise process control to ensure passivation structures protect against UV damage.
- ZnO Coatings:
- Zinc oxide (ZnO) coatings have shown promise in blocking UV radiation while maintaining transparency for visible light, potentially offering another solution.
- Glass Coatings:
- Applying coatings on the front of the cell or using glass with anti-reflective and anti-soiling properties can further mitigate UV damage.
- Regular Maintenance:
- While not directly mitigating UV damage, regular cleaning of solar panels can help maintain efficiency by removing dirt and debris that can exacerbate degradation.
These solutions aim to either prevent UV radiation from reaching the solar cells or enhance the cells’ resilience to UV exposure.
