“…4 The thickness of the absorber layer greatly influences the efficiency and performance of a PSC which were discussed in most of the earlier literatures. 15,21 The efficiency increases with increasing the thickness of absorber layer and an optimized thickness around 350-450 nm is selected so as to reduce the recombination rate. 15 The trap defect densities N t of the perovskite absorber layer and the acceptor doping N a of the tin perovskite are considered as key parameters to be varied to study their effect on the efficiency.…”

“…The analytical studies on optimization of high efficiency lead free PSC as referred in various literatures 9,10,20 using SCAPS were an added advantage to explore more prospects in this field. In our earlier works, 21 we have simulated the ZnO based PSC using Cu 2 O as HTM which reported an efficiency of 22.77%, but no interface defect layers were considered in SCAPS platform.…”

Perovskite solar cells have been in the lime-light of emerging photovoltaic technology owing to their rapid rise in efficiency. The solar capacitance simulator (SCAPS −1D) is a simulation tool that can be used to investigate on the factors that affect the performance of planar perovskite solar cells. In this work, a simulation model has been developed to investigate the performance of metal oxides as charge transport layers for lead and tin based perovskite solar cells. The simulation study on the optimization of energy band gap and electron affinity of ZnO electron transport material with lead/tin perovskite using inorganic metal oxide Cu2O as hole transport materials is done. The influence of trap defect density (Nt) and acceptor doping concentration (Na) of the perovskite layer on the solar cell performance is also evaluated. The doping concentration and defect density of the perovskite layer greatly influence the recombination rate which determines the efficiency of perovskite solar cell.The common p type metal oxides CuO and NiO are experimented for the perovskite solar cell using lead/tin perovskite. The simulation results prove Cu2O as the best metal oxide hole transport material that can be utilized for efficient ZnO based perovskite solar cells.

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.

“…ZnO has higher electron mobility than TiO2 which enhances electron transport rate and possibly lower recombination rates. Additionally, ZnO improves photon transmission in the visible spectra, which broadens the perovskite absorber layer's absorption spectrum(Aseena et al 2019). Therefore, it was found that ZnO is the most suitable ETL materials with PCE 14.68%.…”

Numerical simulation of a lead-tin perovskite (MAPb0.75Sn0.25I3) solar cell was conducted. The simulation was validated against measurements (Li et al. J Mater Chem C Mater 5 (2017) 2360–2367. https://doi.org/10.1039/C6TC05325D) and the photovoltaic conversion efficiency (PCE) closely matched the measured value, 12.19 ≈ 12.08%. Subsequently, optimization strategies to enhance the SC performance were pursued. Doping hole and electron transport layers (HTL, ETL) with various elements as well as adjusting HTL, ETL, and perovskite thicknesses have improved PCE and carriers’ extraction. These optimizations led to an enhancement in PCE to 12.93%. Further improvements using Copper oxide (Cu2O) as HTL yielded a PCE of 13.38%. Doping Cu2O with Tellurium pushed PCE to 14.73%. Copper doping of Zinc Oxide outperformed other ETLs and increased PCE to 15.33%. Overall, these findings represent significant strides in advancing the design of perovskite solar cells, providing valuable insights for further enhancements in photovoltaic conversion efficiency.
