The market share of high-efficiency, negatively-doped, “n-type” solar products, primarily tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) panels, will reach 25% to 30% this year, compared to just 7% in 2022. By 2024, n-type technology will surpass paasivated emitter rear contact (PERC) to become the next-generation mainstream cell tech. InfoLink has found multiple niches along the supply chain that are affected by this switch in technologies, including the supply of high-density wire mesh used in the screen-printing process.
