“…In particular, the FF of the device, which represents the effectiveness of charge transport in the device without any recombination losses, shows a reduction when back contacts with low value of work function are employed. This indicates that the recombination losses are high when low‐ work function back‐metal contacts are incorporated into the device structure 38 . The present study shows that the decrease in FF with decrease in the work function value of the back‐contact metal is higher for PSCs with Sn based perovskite absorber layers when compared to that with Pb based perovskite absorber layers.…”

“…The present study shows that the decrease in FF with decrease in the work function value of the back‐contact metal is higher for PSCs with Sn based perovskite absorber layers when compared to that with Pb based perovskite absorber layers. This is because the Sn based perovskite absorber layers have more defect centres and recombination centres than the Pb based perovskite absorber layers 38 . The study shows that Au can act as a suitable back contact for PSCs.…”

Summary n this study, SCAPS 1D software package is used for modelling tin based mixed halide perovskite solar cells (PSCs) with IGZO and CuO as electron transport material and hole transport material, respectively. Photovoltaic performance parameters of these PSCs are compared to that of pure lead based and lead‐free PSCs with the same charge transport layers. The study shows that the pure tin‐based PSCs are superior in performance to other device configurations. IGZO and CuO are found to be better substitutes for the commonly used unstable and expensive transport layers, TiO2 and SpiroMeOTAD. The study also shows that back metal contacts with work function above 5.5 eV provides stable performance parameters. The study includes an analysis of the influence of various input parameters of the perovskite absorber layer‐ thickness, dopant concentration, total defect density, band gap and electron affinity‐ on the photovoltaic performance parameters. PSCs with MASnI3 as absorber layer show the best performance with a fill factor (FF) and a power conversion efficiency (PCE) of 68.38% and 25.08%, respectively. The effect of internal resistances and temperature dependence are also analysed. For PSCs with single halide perovskites as absorber layer, even a low value of series resistance of 5 Ω cm2 degrades the performance of the device and a large value of shunt resistance of 5000 Ω cm2 enhances the performance parameters of the device.

“…29 The FF relates to charge route resistance and represents the efficiency with which holes and electrons transit the cell without loss. 31,32 As the perovskite's thickness increased, the ll factor decreased. FF decreased from 78.3% at 100 nm to 43.29% at 1000 nm as the thickness increased.…”

As perovskite solar cell (PSC) technology is about to be commercialized, the use of toxic and organic material is still a problem. At the same time, CsSnI 3 has received widespread attention because of its narrow bandgap and non-toxicity. In this study, we use the wxAMPS tool to investigate the limitations of Sn-based all-inorganic PSCs, using CsSnI 3 perovskite as the absorption layer and Au as the back electrode to create non-toxic all-inorganic PSCs. CsSnI 3 is a narrow-band material; the absorption range can be extended to the near-infrared spectral region, and it has a very high hole mobility. Therefore, this article first compares several potential inorganic electron and hole transport layers (ETLs and HTLs), and the results show that C 60 ETL and MoOx HTL are the most suitable materials. Moreover, the device performance is further improved by optimizing the absorber thickness as well as the doping density. Under optimized conditions, a conversion efficiency of 19.25% is obtained for the FTO/C 60 /CsSnI 3 /MoOx/Au PSCs, indicating that there is much room for further performance enhancement. The photovoltaic performance parameters achieve their optimum value at an absorber thickness is better among the range of 100-1300 nm and doping density of 10 19 cm −3 . This shows that the proposed non-toxic all-inorganic PSCs have broad prospects in future photovoltaic and optoelectronics applications, and provide theoretical guidance for the manufacture of a non-toxic and inorganic PSCs.
