Dear Frds,
I am working in the field of Sb2S3 based solar cells. From the literature they stated that after coating Sb2S3 film in CBD technique, the film kept in the N2 or Ar atmosphere at 300 C. After removing from the furnace they got brown crystalinte Sb2S3.
Hence,if any possibility to obtain the crystaline Sb2S3 in without N2 or Ar atmosphere?
Solar cell technology is a highly sensitive industry and based on the synthesis of products doped with some other species. The doping must be highly controlled and the high temperature and rather vacuum conditions are prone to contamination from other available species and/or oxidation. Thus, to keep the control of dopant percentages, any other source of contamination must be kept away from the reaction system. The Ar or to a lesser degree N2 atmosphere will help achievement of such a goal. The technology gets more expensive is a direct consequence of such high purity reactants and the control of reaction conditions.... Good luck.
Dear John,
Sulfides are very sensitive to atmosphere and can form oxy-sulfides if you heat in air.
Thank you Dr.Mahmood and Dr. Rupesh Talewar to sharing the knowledge. It is very useful for me.
