HOSUN BC technology is a cutting-edge solution that inspires both us and our customers.
HOSUN Back Contact (BC) technology represents the next generation of high-efficiency solar modules. By moving all electrical contacts to the rear of the cell, BC eliminates front-side shading, delivering higher power density, better reliability, and outstanding performance in real-world conditions compared to conventional N-Type modules.
Obvious Technical Advantages
Higher Power Output and Efficient Land Utilization
At the same module area: 6–10% higher power compared to N-Type
At the same installed capacity: 6.2% or more less land area required
Innovative full-screen technology with no front busbars
