MM07 – 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. 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.
