Metal-Doped perovskite oxide Ba(1-x)Sr(x)TiO3 as electron transport layer for enhanced photovoltaic performance: An FDTD study
This work investigates the potential of BaTiO3 (BTO) and Sr-doped BaTiO3 (BST) as electron transport layers (ETL) in perovskite solar cells (PSCs) through Finite-Difference Time-Domain (FDTD) simulations. A comprehensive analysis was conducted to optimize the thickness of each layer in the PSC struc...
