Copper sulfide – Preparation of precursor solutions

During my postdoctoral stay at the Physics Institute of BUAP one of my duties is the deposition of thin-film semiconductors. At this laboratory IFUAP-205, I have been doing chemistry activities like the preparation of precursors solutions. In Fig.1, I want to show you three vials with solutions of different molar concentrations used for copper sulfide … Read more Copper sulfide – Preparation of precursor solutions

Laboratory – Bismuth Sulfide thin films

Location: Physics Institute of BUAP, Puebla, Pue. Chemical deposition:  Bi2S3 Bismuth Sulfide Supervisor: M.C Denisse Loeza Chemical deposition of bismuth sulfide from the master thesis work of M.C. Denisse Loeza. This work has the intention to develop new materials (semiconductors) for solar cells. Like the ternary compound Cu3BiS3, which posses potential properties as a p-type … Read more Laboratory – Bismuth Sulfide thin films
