Hybrid organic-inorganic perovskite solar cells (PSCs) are the novel fourth-generation solar cells, with impressive progress in the last few years. MAPbI 3 is a cost-effective material used as an absorber layer in PSCs. Due to the different diffusion length of carriers, the electron transporting material (ETM) plays a vital role in PSCs' performance. ZnO ETM is a promising candidate for low-cost and high-efficiency photovoltaic technology. In this work, the normal n-i-p planar heterojunction structure has been simulated using SCAPS-1D. The influence of various parameters such as the defect density, the thickness of the MAPbI 3 layer, the temperature on fill factor, the open-circuit voltage, the short circuit current density, and the power conversion efficiency are investigated and discussed in detail. We found that a 21.42% efficiency can be obtained under a thickness of around 0.5 μm, and a total defect of 10 13 cm −3 at ambient temperature. These simulation results will help fabricate low-cost, high-efficiency, and low-temperature PSCs.

“…Similarly, the HTL is also chosen from often used materials in PSCs, e.g., P3HT, PEDOT:PSS, Spiro-OMETAD, Cu 2 O, and CuI. Tables 1 and 2 include the basic parameters of the ETL, HTL and CCSC-NCs, which were extracted from the previously published literature [19][20][21]25,26,[32][33][34][35][36][37][38][39][40]. The bulk defect parameters in the absorber layer and the interface defect parameters at ETL/Absorber and Absorber/HTL interfaces are presented in Table 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.

“…However, for the other double perovskite such as Cs 2 TiBr 6 , the efficiency in the experiment was attained to be 2.15% (Chen et al 2018). After performing optimization, the efficiency is reached to 11.49%, which means that efficiency is improved theoretically by 434.41% (Ahmed et al 2021).…”

Double perovskite, Cs 2 AgBiBr 6 , is introduced as a lead-free perovskite solar cell. Device modeling of Cs 2 AgBiBr 6 (DP) was accomplished to obtain the optimum parameters using the Solar Cell Capacitance Simulator (SCAPS). Two devices with two different hole transport layers (HTLs) were investigated, including P 3 HT and Cu 2 O. For both devices with different HTLs, an optimal thicknesses of 1200 nm and defect densities of 1.0 ×10 14 cm -3 for DP layer were attained. For both HTLs, conduction band offset, CBO, is -0.21 eV and valence band offset, VBO, is +0.16 eV. For shallow acceptor doping concentration of P 3 HT and Cu 2 O, the values of 5.0 × 10 19 and 5.0 × 10 17 cm −3 were obtained, respectively. As far as the shallow donor density of electron transport layers (ETLs) is concerned, for both cases, the optimum value of 5.0 × 10 19 cm -3 were achieved. For capture cross section, , , in absorber layer for both HTLs, the optimal value at , of 10 −20 cm 2 for , (defect density of DP) is 10 16 cm −3 , at , of 10 −19 cm 2 for , is 10 15 cm −3 , at , of 10 −18 cm 2 for , is 10 14 cm −3 , at , of 10 −17 cm 2 for , is 10 13 cm −3 , and at , of 10 −16 cm 2 for , is 10 12 cm −3 . For P 3 HT device, the interface defect density of P 3 HT/Cs 2 AgBiBr 6 is occurred at 1.0×10 14 cm -2 , and for Cs 2 AgBiBr 6 /SnO 2 is happened at 1.0×10 9 cm -2 . For Cu 2 O device, the interface defect density of Cu 2 O/ Cs 2 AgBiBr 6 is befallen at 1.0×10 13 cm -2 , and for Cs 2 AgBiBr 6 /SnO 2 is happened at 1.0×10 10 cm -2 . As for radiative recombination, for P 3 HT device, the optimal value is happened at 2.3×10 -13 cm 3 /s, however, for Cu 2 O device is occurred at 2.3×10 -12 cm 3 /s. Finally, for P 3 HT device, a maximum power conversion efficiency, PCE, of 11.69% (open-circuit voltage, V oc , of 2.02 V, short-circuit current density, J sc , of 6.39 mA/cm 2 , and fill-factor, FF, of 0.90 (90% )) were achieved, and for Cu 2 O device, a PCE of 11.32% (V oc of 1.97 V, J sc of 6.39 mA/cm 2 , and FF of 0.895 (89.5% )) were attained. This is the highest efficiency for Cs 2 AgBiBr 6 double perovskite solar cell which was achieved till now. Finally, our results are providing towards fabricating a lead-free and inorganic solar cell.Keywords Cs 2 AgBiBr 6 . Double perovskite solar cell. Lead-free perovskite. Conduction band offset (CBO).
