Volume exclusion effects in perovskite charge transport modeling

Due to its flexibility, perovskite materials are a promising candidate for many semiconductor devices. For example, Perovskite Solar Cells (PSCs) have become recently one of the fastest growing photovoltaic technologies [1]. In this work, we take volume exclusion effects into account by formulating two different current densities – either treating the mobility or the diffusion as density dependent while the other quantity remains constant. Finally, we compare both fluxes within drift-diffusion simulations performed by two different open-source tools.
