HJT BACK-SIDE FINGER PASTE, FRONT AND BACK-SIDE BUSBAR PASTE

Conductive pastes for the main grid, designed for high-efficiency crystalline silicon HJT solar cells and IBC cell string welding, exhibit excellent conductivity, low contact resistance, and a welding tensile strength exceeding 1.5 N/mm after curing. Conductive pastes for the sub-grid in high-efficiency crystalline silicon HJT solar cells possess outstanding printing characteristics and low resistivity. They can establish good ohmic contact with TCO film layers, resulting in lower contact resistance. PRODUCT CHARACTERISTICS 1. Outstanding Printing Characteristics 2. Enhanced Electrical Conductivity with Low Resistivity 3. Robust Welding Bonding Strength
