Multi-Crystalline Silicon Solar Cell 3 Busbars(Continuously)

Characteristics

High photoelectric conversion efficiency and reliability. A unique technology is used during the diffusion process to ensure uniformity. Its external uniformity is controlled with the use of an advanced PECVD forming technology, giving each solar cell its smooth surface coated dark blue silicon nitride antireflection coating. A high-quality metal paste is applied to each cell's back and lining to guarantee good electrical conductivity, reliable electrode absorption and adhesion. High-precise PSG etching and texturing makes each cell easier for post-production welding and laser cutting.
