Multicrystalline Solar Cell

Features of Multicrystalline Solar Cell
1. Multicrystalline solar cells have reliable performance, high photoelectric conversion performances, and usually are used in large-scale applications and industrial production. The photoelectric conversion rate can be up to 10% when the cells are manufactured in large scale. It can reach 18% in laboratory.
2. We adopt unique diffusion technology to ensure uniformity of diffusion.
3. Our multicrystalline solar cells are coated with dark blue silicon nitride anti-reflection film through advanced PECVD film technique.

4. High-precision screen printing and high flatness makes solar cells easier for welding and laser cutting.

5. Electrodes and the back surface are made by high-quality metal slurry, resulting in good conductivity, reliable adhesion and have good weldability characteristics.
6. We conduct quality improvement management system and strict data control system to ensure multicrystalline solar cells are reliable and stable.
7. Calibration film comes from ISE laboratory, while we carry out strict GRR tests inspections, which ensures accuracy of multicrystalline solar cells' energy conversion efficiency.
