"Adopt the best Multi Busbar (MBB) pattern design to reduce shading area, with a maximum conversion efficiency of over 24.9%."

"Double-sided passivation layer (Doping Poly-Si, AlOx) reduces defects, providing superior passivation performance."

Carriers pass through the ultra-thin silicon oxide layer via quantum tunneling effect, thereby reducing recombination probability

The silicon wafer substrate is upgraded from P-type monocrystalline to N-type monocrystalline, eliminating the issue of light degradation
