Abstract
Extensions for perovskite solar cells (PSCs) within the solar cell simulation tool Quokka3 are presented, accounting for ion migration. In the “1D detailed solver” the fully coupled equations describing semiconductor carrier transport, ion transport (anions and cations) as well as the general Shockley-Read-Hall formalism (trapping) are implemented, both as steady-state and transient mode. Numerical challenges arising from the narrowness of the Debye layer and the large difference in times scales between semiconductor and ion transport are successfully addressed. Example simulations are presented, showing the influence of pre-bias voltage on fast JV-sweeps, as well as an interaction between ion redistribution and surface recombination that replicates transient open-circuit voltage responses in a MAPbI3 PSC.
