Abstract : Fabrication of a fully screen-printed device in air ambient needs a low-temperature process for depositing all of
the layers. In this study, CeO2 is proposed as a suitable ETL for fabricating low-cost and stable device at room temperature.
The simulated standard device with TiO2 ETL agrees with the highest theoretical efficiency of 19.08% reported for FASnI3
based PSCs. By optimizing the defect density in the interface of TiO2/FASnI3 the efficiency of standard device calculated.
The optimization of perovskite thickness using SCAPS-ID software in present study enhanced the final optimized PCE of
standard device to 19.48%. Then, the effect of TiO2 replacement with CeO2 ETL revealed efficiency of modified device to
23.42%. By changing the perovskite thickness vs ETL thickness, acceptor density of FASnI3/donor density of CeO2. The
results of this study offer significant insights for enhancing the efficiency of printable FASnI3 based PSCs by replacing TiO2
with CeO2
