Last November 24th was the first day I got into the BUAP Science Institute (ICUAP). Then, we took photographs in front of the Research Semiconductor Devices building to remember this moment. In the main picture of this post, you can observe Dr. Roman Romano, who is the principal researcher (PI), and me. My postdoctoral project is scheduled from October 2021 to September 2022. Now, I am building thin-film solar cell prototypes made of antimony chalcogenide as the main absorber layer. This project is funded by the Conacyt postdoctoral fellowship to impulse the Mexican PhDs in their early days of an…

In the new Postdoctoral project, we are developing thin-film solar cell prototypes. However, some days ago I realize we will require the values of the solar irradiance W/m2 to determine the conversión efficiency $\eta =$ (VocJscFF)/(1000 W/m2) of our cell prototypes. The problem here is we will require an AM1.5 Solar simulator or a pyranometer to calibrate the irradiance (W/m2) of a light source. The possible solutions In my opinion, there are two ways to have these solar irradiance values: a) Fabricate a low-cost pyranometer using silicon photodiodes; b) Calibrate a reference solar cell (Si, crystalline or monocrystalline) using a…

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 . 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 for…
