We will polish and regenerate test wafers and reprocess them into wafers for solar cells.
We will polish and regenerate used test wafers or rejected prime wafers at the customer's site, and reprocess them into wafers for solar cells. By polishing in the range of 3 to 20 mm, it is possible to remove impurities and surface scratches that cannot be achieved through chemical regeneration. For more details, please contact us or refer to our catalog.
