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…

Talking about strategies for high efficiency kesterite solar cells

Dr. Edgardo A. Saucedo visits BUAP after the MRS congress in Cancun, Mexico and gives us a motivational talk about kesterites PV technology. He is the leader of the Solar Energy Materials and Systems Group at IREC and leads the European STARCELL project too. Kesterites are a promising PV material, it's metal elements, Copper, Zinc, and Tin are abundant on earth crust. This material owns a tetragonal lattice similar to commercial PV technology. As Dr. Saucedo said, they come from the royal family of photovoltaics. Kesterites comes from the royal family of photovoltaics   Source: PV-Education Crystal structure of the royal family…
