PERC Cell

A "classic" technology in the photovoltaic industry, it effectively captures more light energy through back passivation technology. With a mature and stable process system and high cost-performance ratio, it remains the main choice for global photovoltaic installations, especially suitable for large-scale ground power plant projects pursuing reliability and rapid commissioning. In recent years, it has continued to optimize llization processes to tap potential.
