Best-in-class solution for edge isolation, polishing and glass removal

The RENA InOxSide® 3 automated processing equipment is designed as an integrated solution for edge isolation, rear side polishing and doped glass removal of silicon solar cells. Using the process for lowest cost of ownership and best performance, the InOxSide® technology is the best choice for fabrication of Al-BSF, PERC and PERT silicon solar cells. It is based upon the RENA NIAK inline platform.

Features and Benefits

  • Fully automated wet chemical single side etching in an inline type process on 5/6 lanes
