Among the challenges are facing inorganic lead-free perovskite solar cells is the rapid oxidation of Sn+2 to Sn+4 which affects the quality of the perovskite layer, and that makes the experimental progress of these alternative solar cells hardly achievable. The Drift-diffusion simulation is a helpful way to figure out the macroscopic parameters that are responsible for low performance in CsSnI3-xBrx  PSCs and also it can be a pre-design for high efficient inorganic Lead-free PSCs.The defect density (quality of fabrication) in the bulk harvest layer and at the selective layers have found to be a crucial key to boost the performance of inorganic lead-free PSCs.

This work has received funding from the European Union H2020 program under Excellence research, and Parasol from Spanish ministry of Science and Innovation.
