The company’s decision to invest in heterojunction technology (HJT) cell technology in addition to focusing on producing TOPCon is a reflection of its commitment to innovation and efficiency in the solar industry. HJT has recently gained attention as a promising technology in the n-type sector due to its potential for better performance in challenging conditions and long-term cost reductions compared to TOPCon.
According to Zhang, the company’s choice to utilize a copper plating process in its HJT cell production instead of the traditional silver grid line printing process has helped reduce costs and resulted in an approximately 0.5% increase in average cell conversion efficiency. The use of silver in solar cell production, particularly in HJT technology, is becoming a growing concern in the industry as solar production continues to rise. A recent feature published by PV Tech Premium highlighted the use of precious metals in solar cell production.
The company’s focus on both TOPCon and HJT technologies reflects its commitment to innovation and improving efficiency in solar cell production. By exploring alternative processes and materials, the company hopes to contribute towards the ongoing development of the solar industry.
