Abstract - The performance of solar systems based on organic-inorganic halide perovskite materials has rapidly improved, and they are rapidly approaching commercialization. Lead-free perovskites have recently gotten a lot of press as a potential replacement for harmful leadbased compounds. We present the optimized version here. Numerical simulations of a methylammonium tin iodide (MASnI3)-based perovskite solar cell simulation. Different important characteristics, such as hole transport layers (HTLs) and doping, have an impact. The impact of density, thickness, and fault density on device performance is thoroughly investigated by using numerical simulation. The hole in the optimal device architecture is copper (I) oxide (Cu2O) and TiO2 as the electron transport layer, the maximum power conversion efficiency of 27.43 percent is achieved. The current density in the short circuit is 25.97 mA/cm2, the opencircuit voltage is 1.203 V, and the fill factor is 87.79 percent. This suggests that by tweaking device settings, highperformance lead-free perovskite solar cells could be achieved experimentally in the future.
Key Words: Efficiency, Solar Cell, Perovskites 1. INTRODUCTION Perovskite solar cells (PSCs) have proven to be one of the most promising. Power conversion efficiency (PCE) Over 25% on a single junction architecture, this can be difficult if it is a conventional silicon solar cell and is moving toward commercialization. Only over 10 years after its founding. But the road to the industrialization of PSC a handful of serious factors like device stability in the air below Lighting and toxicity of the materials used. Almost so far Successful compositions for perovskite solar cells Methylammonium (CH3NH3 +) (MA), formamidinium (NH2CHNH2 +) (FA), and A cation site cesium (Cs +), B cation site lead (Pb), and ABX3 Perovskite structure X anion site iodine (I), bromine (Br) [Five]. However, the presence of toxic heavy metals such as lead is associated with it. The entire life cycle of perovskite solar cells is a major concern from an environmental point of view. Therefore, the next high Efficiency, yet more research communities and industrialists doubt its future paving the way for lead-free perovskite material. That's why researchers are trying to study lead-free perovskite. Material for solar cells. Many lead-free perovskite absorbers. The © 2022, IRJET

Further improvement in tin-based perovskite solar cells can be achieved by optimizing numerous parameters as well as device configurations, which can serve as a guide for future research. More enhancement through experimentation. This simulation work has resulted in a perovskite-based on methylammonium tin iodide (MASnI3) has been developed. Factors like as the thickness and doping levels of different layers, such as the electron layers of transport, perovskite absorber layer, and hole transport layer have been altered, and their consequences have been considered further performance enhancement defect densities have also been increased. Maximum achievable efficiency is 27.43%, which is the greatest reported to date. Any simulation method will yield a value in this scenario.
2. Methodology Comprehensive research was conducted during this simulation work. For MASnI3 as a light absorption material. A negative feature of this material, which has been attracting attention in recent years, is this work. Unlike lead-based perovskite materials, it has non-toxic properties. MASnI3 can be a viable and high-contrast alternative to MAPbX3. The created configuration is one of the most important aspects of the simulation. It will be executed. This task will perform a device simulation Cleavage configuration of FTO / TiO2 / MASnI3 / HTL / Au. shown In the figure. 1. Light passes through the FTO edge and MASnI3 is Adopted as the main light absorption layer sandwiched Fluoride-doped tin oxide (FTO) is used between ETL and HTL Gold (Au) as front and rear metal contacts.
