We report, large efficiency improvement ∽4.5 times in a solar cell based on earth abundant low cost SnS absorber with configuration; Glass/Mo/SnS/CdS/i‐ZnO/AZO/Al in sharp contrast to prior experimental report in literature. Efficiency enhancement is attributed to tailored design at the absorber/buffer interface implemented via two‐step design modification vis‐à‐vis experimental benchmark. Design tailoring using simulation comprises substitution of sulfur composition in SnS by Se followed by replacing CdS buffer layer with wide bandgap, non‐toxic Zn (O, S). The effect of sulfur composition variation by Se (i.e. SnS1‐xSex) indicated an optimal Se mole fraction (x = 0.4) exhibiting maximum efficiency. In addition, optimization of the thickness, carrier density and bulk defect density of SnS1‐xSex absorber resulted in improved design. Replacing CdS buffer layer by ZnO1‐ySy in SnS absorber based solar cell resulted in substantial improvement in device parameters; open circuit voltage (VOC) ∽86% and current density (JSC) ∽78% due to optimal band alignment at the SnS1‐xSex/ZnO1‐ySy heterojunction. It occurred when the sulfur mole fraction is 60% in the absorber layer and 70% in the buffer layer causing efficiency rise to ∽17.87%. An optimal design comprising all the parameters including metal back contact work function, series and shunt resistance delivered an efficiency ∽19.2%.This article is protected by copyright.

Summary Mixed cation perovskite type materials have recently shown considerable potential in high‐efficiency single‐ and multi‐junction solar cell devices. However, the operating principles of multiple cation‐based perovskite solar cells are currently poorly understood. Furthermore, the photovoltaic performances of mixed cations‐based perovskites solar cells are investigated using device simulator program. Inorganic TiO2 and Cu2O were used as electron transport layer and hole transport layer, respectively, because of their better performance. The impact of thickness, doping concentration and density of defect is examined using on the device performance. In addition, the effect of band offsets on performance was also investigated through altering the electron affinity of interface layers. Our calculated results reveal that a 700 nm absorber thickness is appropriate for a good solar cell device. Furthermore, impressive cell efficiency findings were obtained by adjusting defect density (1015‐1016 cm−3) of the mixed perovskite active layer. The optimum conduction and valence band offsets, respectively, were determined to be 0.1 to 0.4 eV and 0.1 to 0.1 eV, allowing for a good performance of mixed perovskite devices. As an alternative to typical halide perovskite solar cells, our findings can be utilized to design and construct efficient mixed cations perovskite solar cell devices.

Tin Sulfide (SnS) is a promising absorber material for solar energy harvesting owing to the high absorption coefficient. Here, a novel inverted planar heterostructure of SnS based solar cell (ITO/NiOX/SnS/ZnO/Al) has been proposed for better efficiency among the different electron transport layers (ETLs), PCBM, C60, CeOX, and ZnO. The performance of the SnS based solar cell was theoretically studied by the Solar Cell Capacitance Simulator (SCAPS) software. Initially, we have been observed the device performance with different ETL materials to find the better ETL material. The layer parameters of the HTL, absorber layer, and ETLs have been optimized to find out the best performance of the device. The device showed efficiencies of around 26.44%, 26.33%, and 26.38% with the ETLs PCBM, C60, and CeOX respectively. The maximum power conversion efficiency (PCE) of ~28.15% has been observed after incorporating ZnO ETL in the designed architecture of the SnS-based solar cell. Then, we have been investigated the performance of the SnS-based solar cell with ZnO ETL for the various value of carrier concentration, thickness, and bulk defect of the SnS absorber layer, defect of the interfaces of NiOX/SnS and SnS/ZnO, back metal contact's work function, and its operating temperature. The variation of the different parameters has exhibited a substantial effect on the device performance. The VOC, JSC, FF, and PCE of the optimized SnS-based solar cell with ZnO ETL showed 0.8954 V, 37.316452 mA/cm2, 84.24%, and 28.15%, respectively. The visualization of the results indicates that ZnO might be a potential ETL for the highly efficient, low-cost inverted planar solar cells based on SnS.
