IMRC 2021 Meeting - Cancun Mexico - Virtual Poster Mode

The International Material Research Congress (2021-IMRC) is coming next August 15-20th. In this event, I'll be attending the Symposium C7 - Photovoltaics, Solar Energy Materials, and Technologies to present my research about the development of silver antimony sulfide selenide AgSbS2, AgSbSe2, AgSb(S,Se)2 for solar cells [zotpressInText item="{6612042:JUKWBKTL},{6612042:YYSGZIWM}"]. I have a story with the IMRC-Congress. When I was doing my Ph.D. project, My Advisor preferred to attendant the MRS-Fall and MRS-Spring meeting in the USA because IMRC at the Caribbean of Mexico seems like a vacation! I don't know your experience, but In mine, a research meeting let me travel abroad…

Chemical solutions for CuS deposition

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 thin-film deposition: Copper chloride (CuCl2), Sodium hydroxide (NaOH) and Thiourea (NH2CSNH2). These solutions were dissolved in deionized water and stirred using a magnetic plate. What I have learned here is that solutions should be prepared one day before or in the moment of the chemical…

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.
