      Detailed Specs

      Nines are offering a range of processing tools with the patented ADE (Atmospheric Dry Etch) technology at the core.This technology offers a range of benefits to the cell manufacturer and an efficient texturing method for diamond wire cut multi-crystalline mc-Si wafers.

      BENEFITS – FLEXIBLE, FUTURE PROOF TECHNOLOGY
      -Enables the use of diamond wire cut wafers, epitaxial wafers, cast wafers, mono and multi.
      -Delivers low reflectivity textures, outperforming industry standards with wafer surface reflectivity Rw values adjustable within a range from 19% down to 2% (black silicon)
      -True Single side processing – the back side is untouched
      -Enables advanced cell architecture whilst also reducing processing costs
      -Facilitates improved scalability of the manufacturing process – inline, high throughput, On-Site generation of Etching gases
      -Improves the overall sustainability of the manufacturing process, using only Zero Global Warming otential (GWP) Chemicals.
