A lead-free, completely inorganic, and non-toxic Cs2TiBr6-based doubleperovskite solar cell (PSC) was simulated via SCAPS 1-D. La-doped BaSnO3 (LBSO)was applied as the electron transport layer (ETL) unprecedentedly in thesimulation study of PSCs, while CuSbS2 was utilized as the hole transport layer(HTL). wxAMPS was used to validate the results of SCAPS simulations. Moreover,the first-principle density function theory (DFT) calculations were performedfor validating the 1.6 eV bandgap of the Cs2TiBr6 absorber. To enhance thedevice performance, we analyzed and optimized various parameters of the PSCusing SCAPS. The optimum thickness, defect density, and bandgap of the absorberwere 1000 nm, 1013 cm-3, and 1.4 eV, respectively. Furthermore, the optimumthickness, hole mobility, and electron affinity of the HTL were 400 nm, 102cm2V-1s-1, and 4.1 eV, respectively. However, the ETL thickness had anegligible effect on the device's efficiency. The optimized values of dopingdensity for the absorber layer, HTL, and ETL were 1015, 1020, and 1021 cm-3,respectively. Herein, the effect of different HTLs was analyzed by matching upthe built-in voltage (Vbi) in respect of the open-circuit voltage (VOC). It wasfound that the Vbi was directly proportional to the VOC, and CuSbS2 was thechampion in terms of efficiency for the PSC. The optimum work function of metalcontact and temperature of the PSC were 5.9 eV and 300 K, respectively. Afterthe final optimization, the device achieved an exhilarating PCE of 29.13%.
