“…The active layer's total defect density is another crucial parameter that can significantly affect the device performance. The higher defect concentrations in the absorber layer cause a higher recombination due to the generation of pinholes, a higher rate of degradation of film, a reduced stability and a reduced overall performance of the device [ 33 ].…”

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.

“…In the present simulation, all the electrical and physical parameters are collected from previous reported studies, as listed in the Table 1. 22,46,50,[53][54][55][56][57][58][59][60][61] The interfacial contact between ETL/absorber and absorber/HTL play very crucial role in the PSCs. Two defect states such as TiO 2 / MASnI 3 and MASnI 3 /Spiro-OMeTAD are taken into consideration to understand the carrier recombination and tabulated in Table 2.…”

Summary Recently, lead‐free perovskite solar cell (PSC) heterostructure using CH3NH3SnI3 (MASnI3) absorber layer received significant attention due to their superior device performance. However, the effect of deep defect state on device performance is only little known about the MASnI3 absorber based PSC. In the present study, initially we optimized the power conversion efficiency of the device via the bandgap tuning and electron affinity variations in MASnI3 absorber layer using SCAPS‐1D simulator. Thereafter, the capacitance‐voltage (C‐V), Mott‐Shottkey (MS) (1/C2‐V) and conductance‐voltage (G‐V) measurements are performed through simulation approach, which confirmed a solid sign of deep defects in the perovskite heterostructure device. In addition, temperature dependent capacitance‐frequency (C‐f) characteristics confirmed the clear expectancy of thermally‐induced variations in capacitance (or dielectric constant) under illumination and dark, respectively. Further, supremacy of the space charge region in MASnI3 based PSC is confirmed from the voltage dependent semicircular nature of the Nyquist plots. Shrink in the semicircles of the Nyquist plots with the increase of the forward bias voltage also confirm the improvement of carriers under forward bias which increase the conductivity and therefore decrease the impedance.

“…In the process of simulating and optimizing solar cells, SCAPS-1D software developed by M. Burgelman of the University of Gent in Belgium is applied, which is suitable for simulating cells with various homojunction and heterojunction structures. Its basic principle is to solve the Poisson equation and current continuity equation under these constraints based on the established battery structure model and the input material parameters [18,19].…”

Recently, organic-inorganic halide perovskite solar cells (PSCs) have received extensive research in the field of optoelectronic materials due to their unique optical and electrical properties, especially lead-based PSCs. However, the toxicity and stability of these devices, as well as the expensive hole transport layer (HTL) and other factors inhibit their commercial production. In this work, the non-toxic tin was applied as the battery material, the perovskite solar cell adopts an inverted HTL-free structure, and the one-dimensional solar cell capacitor simulator SCAPS-1D (Solar Cell Capacitance Simulator) was adopted for numerical simulation and found that FTO/CH3 NH3 SnI3 /C60 /Au structure PSCs also showed excellent photovoltaic performance. We studied the influence of the thickness of the absorber layer, the defect density, the doping concentration of different layers, and the thickness of the electron transport layer (ETL) under different directions of illumination on the battery performance. The simulation results show that the optimized inverted HTL-free tin-based PSCs based on C60 are with inspiring performance: a short-circuit current density (JSC ) of 30.1646 mA/cm 2 , open-circuit voltage (VOC ) of 1.0465V, fill factor (FF) of 59.49% and power conversion efficiency (PCE) of 18.78%. We also introduced light from different directions to irradiate PSCs, and the results show that the HTL-free perovskite adopting an inverted structure can retain the light intensity of the irradiated perovskite layer to the greatest extent and exhibit superior performance. Based on the inverted HTL-free tin-based PSCs, we also investigated the performance parameters of ETL batteries with different materials. This work provides new ideas for PSCs development in the future.
