SMBB design with Half-Cut Technology decreases power losses, offers better shading tolerance, and improves the resistance to micro-cracks and hotspot effect.
By the cell's natural bifacial structure, bifacial solar modules can generate power from both sides, which brings more energy yield.
With no B-O bond and TCO film, LID and PID effects can be eliminated, which means less power loss and longer service life.
Sealing with PIB-based sealant for stronger water resistance, and greater air permeability to extent module lifespar.
The superior power output of the HJT solar module can effectively reduce the LCOE and bring more investment returns to customers.
