Monocrystalline N-type

a. Superior Carrier Lifetime

• The Monocrystalline N-type utilizes phosphorus-doped silicon substrate with carrier lifetimes exceeding 2ms, significantly reducing electron-hole recombination losses.
• Advanced hydrogenation passivation technology further enhances minority carrier diffusion length (>500μm), a key performance booster for this technology.

b. Bifacial Design Compatibility

• It supports bifacial power generation (bifaciality factor up to 85%), capturing reflected light from ground surfaces to boost total yield by 10-25%.
• Transparent backsheet options are available for specialized applications (e.g., agrivoltaics), expanding the versatility of the Monocrystalline N-type.

a. Oxygen-Free Crystal Growth

Czochralski process with magnetic field confinement achieves oxygen content <5ppma, minimizing thermal degradation risks.

b. Atomic-Level Surface Engineering

Nano-textured front surface (pyramid size <1μm) combined with triple-layer ARC coating:

SiO₂ (75nm) / SiNₓ (80nm) / TiO₂ (50nm) stack for <2% reflectivity across 300-1200nm spectrum.

c. Advanced Metallization

9-busbar design with silver-aluminum hybrid paste reduces series resistance to 0.8mΩ·cm².

Laser-assisted selective emitter patterning optimizes front contact shading loss (<3%).

Specialized hydrophobic backsheet prevents biofilm accumulation, maintaining >95% performance in water-rich environments.

Customizable transparency (10-40%) for solar windows and façade integration, with 18% module efficiency.

182mm wafer size optimized for rooftop layouts, achieving 420W+ output in <1.8m² area.
