Cu 2 BaSnS 4− x Se (CBTSSe) has recently attracted substantial attention as an emerging chalcogenide material due to its abundant constituent elements and reduced antisite disorders compared the ZnSn(S,Se) 4 (CZTSSe). In this work, reported Mo/CBTSSe/Cd:ZnS Zn 1− Cd S/i‐Mg:ZnO (ZMO)/Al:ZnO (AZO) cell structure with power conversion efficiency (PCE) of 6.17% is used develop baseline model. Afterwards, device performance parameters are fine‐tuned by investigating effect (a) absorber thickness defect density, (b) absorber/buffer conduction band offset, (c) interface (d) anti‐reflection coating at front layer, (e) back contact optimization. The optimized parameter values thickness: 1.2 μm, density: 10 15 cm −3 , alternate buffer layer WS density:10 −2 resulting in PCE 12.94%. Introducing anti‐reflective (ARC) further improves 17.87%. Finally, introducing Ni a instead Mo enhances 20.70%. These results provide insight into possible techniques improve CBTSSe‐based solar cells.
