“…The materials used are TCO (BZO, ZnO and MoO3) act as front contact, TiO2 as Electron Transporting Material (ETM), methyl-ammonium tin iodide (CH3NH3SnI3) as light absorbing layer, spiro-OMeTAD as Hole Transporting Material (HTM), Gold (Au) as back contact and SCAPS simulating software. The simulation parameters of those layers were obtained from previous literature [23][24][25][26][27][28][29][30][31][32][33][34][35] and were tabulated in Table 1. The data can be used to investigate the influence of other factors such as series and shunt resistance, defect density etc on the performance of the tin-based perovskite solar cells in planar configuration.…”

Substrates used in perovskite solar cells as front contact are usually transparent conductive oxide (TCO) to allow light to pass through the device. The dominating TCO employed in perovskite solar cells are indium-doped tin oxide (ITO) and fluorine-doped tin oxide (FTO). However, it is imperative to investigate alternative TCOs due to the scarcity of indium metal, relatively low electrical conductivity and high leakage current in ITO and FTO. In this study, simulation has been carried out using Solar Capacitance Simulator (SCAPS) to investigate the efficiency of methyl-ammonium tin iodide (CH3NH3SnI3) based solar cells including various TCOs such as boron-doped zinc oxide (BZO), molybdenum trioxide (MoO3) and zinc oxide (ZnO). TCO parameters such as thickness, donor concentration and operating temperature were varied to study their influence on device performance. The best device performance was achieved using MoO3 with power conversion efficiency of 25.83 % and Jsc, Voc and FF of 32.44 mA/cm2, 0.979 V and 81.38 % respectively. The work shows the potential of fabricating an improved CH3NH3SnI3 perovskite solar cell with MoO3 as front contact.

“…This bandgap tunability provides a good chance to use Tinbased perovskites as a possible substitution for LHPSCs in solar cell applications [15,19]. The major limitation for the tin-based perovskite performance is the oxidation of tin from Sn 2+ to Sn 4+ in the air [22,26,27]. Extensive research increases the stability of the Snbased devices by developing encapsulation processes.…”

“…Due to the results, it can strongly affect the SC performance. The impact of two types of transport metals on the performance was also analyzed, showing that the band offset adjusting of the Cd1-xZnxS layer led to PCE of 18.71% PCE[26].In 2019, Mostafa M. Salah et al replaced Spiro-OMeTAD, the conventional HTM, with CuI and analyzed it with different ETMs CdS, ZnO, ZnSe, and ZnOS as replacement of TiO2, The traditional ETM.…”

With the fast progress of solar cells efficiency in the last few years, hybrid organic/inorganic metal halide perovskite solar cells (PSCs) became a center point of research for a lot of solar cell researchers. The perovskite materials show different merits like longer carrier diffusion lengths, wider-tunable bandgap in addition to higher potential of light absorption. The higher efficiency together with the cheaper fabrication methods makes perovskite solar cells comparable with Si-based solar cells. The PSCs efficiency has a remarkable increase from 3.8% to more than 25.2 %. There is a great need for an overall understanding of the function of each of the solar cell components and its impact on cell efficiency and performance. This review starts with the discussion of perovskite structure (electronic and crystal) based on recent research. The working principles and the fabrication methods of PSCs are also introduced. PSCs evaluation is also analyzed and presented with more details regarding modelling approaches and simulation tools.

“…Despite the rapid improvement in -based perovskite material still, PCE achieved from based perovskite solar cell is very low. This is mainly due to the lack of understanding of device properties and the effect of band structure on device performance [31,32]. to analyze their effects on the cell performance.…”
