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 is where I am doing my postdoctoral project but take it easy. I am not going to explain physic or chemistry stuff.…

Fabrication of Titanium dioxide as a compact layer for Perovskite and thin-film solar cells

Special thanks for Dra Hailin Zao Hu at IER-UNAM who let me collaborate and learn from their group the methodology for TiO2 compact layer deposition.  All the training was possible with the assistance of Ph.D. student Fabian and undergraduate  Ing. Gabriela Abrego from UTEZ. Preparing TCO with magic tape  for HRT layer deposition  Spin coater  and micropipette are the essential tools for TiO2 deposition  First heating of the compact layer over a hot plate : low temperature Second and final heating - Sintering TiO2 on a muffle furnace : high temperature Compact TiO2 layer deposited over a TCO for thin-film chalcogenide or Perovskite…
