“…Both TiO 2 and PCBM have the smallest absolute CBO values, which are smaller than those of the other two materials. TiO 2 used as ETM has a slightly higher PCE than PCBM because the dielectric constant of TiO 2 (ε r = 9) is higher than that of PCBM(ε r = 3.9), which is consistent with the previous literature [ 43 ]. Therefore, we select TiO 2 as the most appropriate ETM.…”

“…The corresponding device performance is presented in Figure 12 . From Figure 12 , it can be seen that Voc, Jsc, and FF decrease with increasing bulk defect density due to the fact that the generated electrons and holes are more easily captured by bulk defects [ 43 ]. The PCE falls from 21.3% to 4.74% when the bulk defect density increases from 10 11 cm −3 to 10 17 cm −3 .…”

“…It shows that Voc, Jsc, and FF decrease with the Cu 2 O/CCSCNCs interface defect density. This trend is attributed to the fact that the higher defect density at Cu 2 O/CCSCNCs interface brings more traps and recombination centers, which results in deteriorating performance of the cells [ 43 ]. Therefore, the PCE decreases from 21.20% to 20.81% with the Cu 2 O/CCSCNCs interface defect density increasing from 10 19 cm −3 to 10 21 cm −3 .…”

In the last decade, perovskite solar cells have made a quantum leap in performance with the efficiency increasing from 3.8% to 25%. However, commercial perovskite solar cells have faced a major impediment due to toxicity and stability issues. Therefore, lead-free inorganic perovskites have been investigated in order to find substitute perovskites which can provide a high efficiency similar to lead-based perovskites. In recent studies, as a kind of lead-free inorganic perovskite material, Cs4CuSb2Cl12 has been demonstrated to possess impressive photoelectric properties and excellent environmental stability. Moreover, Cs4CuSb2Cl12 nanocrystals have smaller effective photo-generated carrier masses than bulk Cs4CuSb2Cl12, which provides excellent carrier mobility. To date, there have been no reports about Cs4CuSb2Cl12 nanocrystals used for making solar cells. To explore the potential of Cs4CuSb2Cl12 nanocrystal solar cells, we propose a lead-free perovskite solar cell with the configuration of FTO/ETL/Cs4CuSb2Cl12 nanocrystals/HTL/Au using a solar cell capacitance simulator. Moreover, we numerically investigate the factors that affect the performance of the Cs4CuSb2Cl12 nanocrystal solar cell with the aim of enhancing its performance. By selecting the appropriate hole transport material, electron transport material, thickness of the absorber layer, doping density, defect density in the absorber, interface defect density, and working temperature point, we predict that the Cs4CuSb2Cl12 nanocrystal solar cell with the FTO/TiO2/Cs4CuSb2Cl12 nanocrystals/Cu2O/Au structure can attain a power conversion efficiency of 23.07% at 300 K. Our analysis indicates that Cs4CuSb2Cl12 nanocrystals have great potential as an absorbing layer towards highly efficient lead-free all-inorganic perovskite solar cells.

“…With inorganic copper oxide (CuO) as HTM, methyl ammonium lead iodide (MAPbI 3 ) based PSCs exhibit high open circuit voltage (V OC ) and short circuit current density (J SC ) 13 . A modelling study on tin‐based PSCs with IGZO as ETM shows a PCE of 23.86% when Cd 0.5 Zn 0.5 S is used as HTM 14 . Another study shows an experimental PCE of 12.16% with CuO as HTM for PSCs with MAPbI 3 as the photon harvesting layer and PCBM as ETM 13 .…”

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.

“…The toxic property of lead (Pb) creates a hurdle in fabricating the cells. Generally, a perovskite solar cell architecture consists of an electron transport layer (ETL) and a hole transport layer (HTL) which in turn maximizes power conversion efficiency (PCE) [1]. The volatility of the organic cation is considered to be a significant contributor to instability, which should be improved using inorganic cations [2].…”

The lead-free double perovskites have recently emerged as promising alternative material for solar cell application. It exhibits encouraging optoelectronic properties, high environmental stability and low toxicity. The double perovskite having two different cations are non-toxic alternatives. The double perovskite Cs2AgBiBr6 has good optical and electronic features. Therefore, it has been used for high-efficiency optoelectronic devices. In this manuscript, we report optimization of active layer thickness of double perovskite Cs2AgBiBr6 for photovoltaic application. For the study, a device FTO/TiO2/Cs2AgBiBr6/Spiro-OMeTAD/Cu was designed. The Solar Cell Capacitance Simulator (SCAPS-1D) was used for one dimensional simulation and analysis. The active layer of 0.1 to 1 m was used for the study and PCE, Voc, Jsc and FF were obtained using simulation. The optimum active layer thickness was found to be between 0.20 m to 0.4 m. The maximum PCE of 3.78 % was found. The solar cell performance can be improvised further by optimizing the defect density of the active layer. Also, the effects of ETL and HTL layer thickness can be further observed for enhancement of PCE. Overall, the encouraging simulation results achieved in this study will provide insightful guidance in replacing commonly used cancerous Pb-based perovskite with eco-friendly, highly efficient inorganic perovskite solar cell.
