VDMA expects copper metallization to take off in next 2 years

At SNEC 2024 in Shanghai, pv magazine spoke with Puzant Baliozian, lead consultant of sector group photovoltaic equipment for Germany’s Machinery and Equipment Manufacturers Association (VDMA). He says tunnel oxide passivated contact (TOPCon) technology will dominate the solar market in the next 10 years and expects module manufacturers will compete to develop more creative product designs. He also believes that copper metallization will gain market share in heterojunction (HJT) module production in the next years. “In the upcoming decade, we will have less than mg/W of silver being used for both TOPCon and HJT technologies,” he stated.
