Our high-reflectivity backsheet substrate (Black High-Reflective for BC Cells) has already been successfully applied in BC solar cell modules, helping to push mass-production efficiencies of BC cells beyond 27% and module efficiencies past 24%. Even compared with upgraded TOPCon modules using half-cell passivation and 0BB technology, BC modules demonstrate a power gain of around 15W.
Since August 2024, several central SOEs and major power investment groups have set up dedicated bidding sections for BC technology, and BC modules combined with 0BB busbar-free technology have achieved premium profitability, breaking distributed rooftop limitations and expanding rapidly into centralized PV applications.
�� Product Highlights
- Proven performance in BC solar modules
- High-reflectivity backsheet substrate boosts light absorption and module efficiency
- Integrates BC cell and 0BB advantages for higher power output
