    Perovskite solar cells have gotten a lot of attention in recent years because of their appealing characteristics, such as higher efficiency in higher spectrum range, low production costs, ease of fabrication, and steadily improving system efficiencies. The development of new manufacturing methods, materials, system architectures, and improved stability have been the subject of research efforts. In this study we have analyzed two optimized cell models which have been simulated in SCAPS-1D and have compared the characteristics between them. The optimization was set to the thickness and doping concentration(NA) of the perovskite layer, electron affinity of the ETM(Electron transporting medium). We used the whole standard spectrum to find the best possible range to get high QE. As different materials are being tested to be used in perovskite solar cell recently, we have switched two substances in the ETM keeping in mind about their optoelectronic qualities and production cost. Then a comparative analysis has been done depending on the I-V and QE characteristics of this two models. The open circuit voltage and the short circuit current have also been taken into account alongside the FF% and conversion efficiency.
