Product Introduction
All back contact solar cells are a new generation of photovoltaic solutions, with both electrodes located on the back of the cell. All back contact solar cells design eliminates front metal shading, significantly improving light absorption capacity and making the cell look more attractive. We carefully manufacture these back-contact cells to ensure their high power output, low series resistance, and good performance for a long time. They are very suitable for high-end residential and commercial solar installations.

Product Features and Applications
Features:
- Zero gridline shadow loss: 100% front utilization enables module efficiency to exceed 22%.
- Reduced hot spot risk: Distributed back-contact topology reduces thermal stress.
- Enhanced durability: Copper-plated back electrodes are corrosion-resistant in high-humidity coastal environments.
- Bifacial compatibility: Transparent backsheet options can additionally obtain 30% energy gain through albedo.
Applications:
- Floating photovoltaic power stations: Corrosion-resistant design is suitable for marine environments.
- Agrivoltaics: The uniform front appearance reduces the visual impact on farmland.
- High-density urban rooftops: The yield per square meter is 8-15% higher than that of PERC panels.

FAQ
Q: How does the back-contact design improve low-light performance?
A: By eliminating front electrode resistance losses, the cell maintains a fill factor of >92% at 200W/m² irradiance, compared with 85% for PERC cells.
Q: Can existing inverters be used?
A: Fully compatible with mainstream 1500V string inverters. Recommended oversizing ratio: 1.3x DC/AC.
Q: What maintenance is required?
A: The self-cleaning coating reduces dust accumulation loss to <3%/year. Annual drone thermal imaging inspection is recommended.
Q: What is the recycling process?
A: After component disassembly, >95% pure silicon wafers and >99% copper can be recovered through electrochemical separation.
