1. High PV conversion efficiency: 15%-19%;
2. Low revers current, high shunt resistance and high reliability;
3. The surface is covered by the anti-reflection coating of deep-blue silicon nitride, so the appearance is good. This coating has good passivation effects. There are two or three main grid lines(silver) on the surface;
4. There is a 2.6mm welding substrate (silver) on the back. The back surface (aluminum) BSF adheres with the eletrodues with high-quality adhesives to garantee the high tension strength and increase the welding fusion.
