Electrical Characteristics




World class high performance monocrystalline solar cells in the market. Applying 4 busbar layout design improves current collection. Thin fingers on the front side and discontinuous busbar on the back side increase the cell efficiency for better performance. Also, the discontinuous busbar reduces the amount of lead/silver paste, and thus help to protect the environment.
