Many different photovoltaic technologies are being developed for better solar energy conversion. Until now, crystalline Si solar cell represents the dominant photovoltaic technology with a market share of more than 94% with an efficiency between (15%-20%). Organic-inorganic halide Perovskite Solar Cell (PSC) has emerged as the most promising candidate for the next generation high-efficiency solar cell technology that attracted interest from researchers around the world due to their high efficiency of more than 24.% in a short period from (2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018)(2019) and low fabrication cost. In this paper, we designed a lead-based PSC model with a cell structure of Glass/FTO
