Outreach day for young girls – Development of Solar cells

February 11th has been designated as the international day of women and girls in science to promote their participation in STEM (Science, Technology, Engineering, Mathematics) activities [1]. For the first time in 2020, the Physics Institute of BUAP (IFUAP) opens its doors to young girls to talk about science and technology. Here, at the BUAP IF2 building, you can find me at the Lab-205 which is designed for the development of hin films and nanoparticles of novel materials. This laboratory…

I replace the battery of my phone, now what?

Last week I was talking about "DIY Culture: Repair and Recycle" where I show you the way I found to replace an old iPhone 6 and keep using it for a while in 2020. But now, there is still a problem. What I should do with the used battery? The answer is to trash it, but correctly. Here, I will show you how to do it and what more we can learn from this technology. Li-ion battery is a highly…

How a Silicon Heterojunction solar cell is made? MRS SciVid-2017 (winner)

Looking for PV-Lab (Photovoltaic Labs ) on the web I found this video which explains the process of the development of silicon (Si) solar cells. It seems interesting so I want to share it with you. The most efficient silicon solar cells in 2020 are developed using Si-heterojunctions (26.7% lab and 24.4% module) [1]. The junction is formed between the crystalline silicon (Eg = 1.12 eV ) and amorphous silicon (Eg = 1.75 eV) deposited on each face of the…
