UltraPure Steam for Solar Cells

Ultrapure steam can be used to form the transparent conductive oxide that improves solar energy capture.  Steam is also used to grow wet thermal thick oxides on the backside for state of the art current isolation in backside contacts. In addition, steam can be used to form isolation layers between films and annealing of films to reduce defects and improve cell efficiencies.

RASIRC technology improves many processes within the solar industry:

  • Passivation: eliminates hydrogen, reducing cost and improving safety.
  • Interlayer Oxide Films: limits boron intrusion.
  • TCO: enables high flow rates without volatizing water microdroplets, improves stability and reliability, and reduces particulates below detection limits.
  • Backside Thick Oxide: reduces non-uniformity in the oxide layer.
