Spyros Orfanoudakis graduated from the Physics Department of the National and Kapodistrian University of Athens (BSc 2020) in the field of Condensed Matter and his thesis is << Photocatalysis in Titania-Based Mesoporous Thin Films>>. Since 2020, he is a MSc student at National Technical University of Athens, Department of Physics, and realizes his experiments at NCSR "Demokritos" under the supervision of Dr. Stergiopoulos. The subject of his thesis
concerns perovskite materials and is expected to be completed in His study is focused on the chemical passivation of electron-rich defects in methylammonium lead iodide (CH3NH3PbI3) perovskite films by incorporating Lewis acids. His research interests include optical characterization (UV-Vis , Steady-State and time-resolved photoluminescence) to determine the absorbance, emission and charge carrier lifetime of the samples and the morphological characterization (SEM and AFM) to probe for potential surface changes.
