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. Fig.1: Washing Bi2S3 thin films after chemical deposition Fig.2: Dry using N2 gas Fig.3:  Another angle showing the base where the glass substrates are held.

Is it hard to get a postdoctoral stay in Mexico?

Coffee cup at IFUAP-BUAP (From MIT)  In Mexico, 2019 is a hard year for Science and technology due to two main reasons: a) Change of Mexican president followed with a change of political flagship and b) Corruption priority besides economical aspects. This year I had the opportunity to apply for a postdoctoral fellowship from Conacyt-International to spend one year at EMPA-Switzerland.  In August, the results came and I was not selected. These results are followed by a reduction of federal found for Conacyt and the government bet for carbon-based fuels.  Fortunately, I had a plan B. I apply for a…
