Supply tightens as n-type expands

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.

Cells are printed with silver paste to create contacts that collect the current generated in the cell. While other approaches have been explored, screen printing has remained the mainstream process for this stage due to its low …
