“…Since the ETL was placed in front of the active layer, the thickness should not be too thick, which can block the incident light transmission nor should not be too thin to optimize the electron transport activity [32]. Several studies on PSC applied TiO 2 -based ETL with thickness in the range 10-700 nm [33][34][35][36][37]. In this study, the thickness of 0.32% Fe-TiO 2 -based ETL was varied by 20 nm, 50 nm, 100 nm, 200 nm, and 500 nm.…”

In the third generation of the solar cell era, significant trends in the development of perovskite solar cells (PSC) were observed. Exploring suitable materials for its wafer structure, such as perovskite and electron transport layers (ETL), were a major emphasis of high-performance PSC development. Because of its matching band structure to MaPbI3, TiO2 is the most often utilized material for ETL. However, in the application of TiO2 to PSC, electron trapping and a wide energy gap become a drawback. The goal of this research is to improve the absorption performance of PSC employing ETL with Fe and Ta-doped TiO2 as well as the thickness of the material. The interaction between the electromagnetic waves of light and the solar cell structure was calculated using Finite-Difference Time-Domain (FDTD) simulations, which resulted in the absorption spectra. In comparison to pure TiO2, which absorbs only 79.5% of the incident light, Fe-TiO2 and Ta-TiO2 as ETL in solar cells have increased absorption spectra to 81.7% and 81.2%, respectively. Finally, we may conclude that the optimum ETL layer parameters are 0.32% Fe doping and a thickness of 100 nm.

“…In this context, these sites are inclined to become the adsorption centers for moisture and O 2 , therefore causing the suppression of PCE and the stability of PSCs. 37 High-quality perovskite film is substantial to resist erosion by moisture and to stabilize the PSCs. In order to investigate the hydrophobicity of pristine and 5% MTP-treated MAPbI 3 layers, water-contact angles were measured (inset of Fig.…”

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).
