Longi and DK Electronic Materials have announced a transition to copper-based metallization in the photovoltaic (PV) industry by 2026, driven by recent shifts in silver prices and growing demand for cost-effective solutions. Experts suggest that while the move to copper is technically and economically feasible, silver will still play a role in specific applications, with a projected usage of 2 to 3 mg per watt. Research is ongoing to enhance metallization processes and further reduce silver dependency in PV cells.
