Sofia Apergi received her Master diploma in 2019, from the School of Applied Mathematical and Physical Sciences at the National Technical University of Athens in Greece. Her diploma thesis focused on the computational studies of materials for photovoltaic applications using density functional theory (DFT). She is currently working on the development of an approximate DFT method, Density Functional based Tight Binding (DFTB), for large scale simulation of perovskite solar cells.
