چکیده	Perovskite-based solar cells have been widely studied in recent years due to their unique properties. Nanostructured Al2O3 were employed as a mesoporous scaffold for fabrication of such solar cells. Morphology and thickness of scaffold were shown to be very important for optimization of conversion efficiency of the cells. In this study charge transport in three different structures usually used in Perovskite-based solar cells with Al2O3scaffold are investigated for the first time. Random walk numerical simulation based on hopping model is utilized for charge transport. Dependency of the diffusion coefficient and collection efficiency of the cells on the morphological parameters is studied here. Optimum thickness for the Perovskite layer and optimum surface roughness and thickness for Al2O3scaffold to reach a maximum efficiency for Perovskite/Al2O3based solar cells are achieved in our simulation
