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 semiconductor for absorber layer on thin-film technology.
