Low-cost Pyranometer and Raspberry Pi Pico – I

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:…

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…

How to fabricate high efficient perovskite solar cells?

My experience on Perovskites solar cells (PSCs) comes from IER-UNAM, where I had the opportunity to take a 1-week course with Dra. Hailin research group. Here, we developed some MAPbI3 Perovskite solar cells with regular n-i-p architecture. Due to the fabrication protocol they were following, we could develop PSCs of up to 12% in our first attempt. Workshop - Development of Hybrid Perovskite Solar Cells - IER-UNAM, June 2019. Imagine how it feels to fabricate a device of 12% of…
