For semitransparent perovskite solar (ST-PSCs) common way to increase their efficiency and decrease their average visible transmittance is to increase the thickness of their absorber material and vice versa.PSCs, or semi-transparent perovskite solar cells, have become a serious player in the photovoltaics space because of their high power conversion efficiencies (PCEs) and adjustable optical characteristics.This abstract offers a thorough summary of current developments, obstacles, and potential future developments in the creation of semi-transparent PSCs.These devices' optical transparency makes it possible to integrate them into a variety of applications where efficiency and aesthetic appeal are essential, like wearable electronics, automobiles, and building-integrated photovoltaics (BIPV).Important developments in the design of materials, such as bandgap engineering and charge transport layer optimization, have greatly improved the stability and efficiency of semitransparent PSCs.Prospects for increasing efficiency and broadening application possibilities appear bright when semi-transparent PSCs are combined with cutting-edge technology like tandem solar cells and flexible substrates.To realize the full potential of semi-transparent PSCs in the renewable energy sector, research initiatives focused on overcoming stability difficulties and scaling up output must continue.CuI was used as the HTL material and simulation results show the best performance in terms of the tradeoff between power conversion efficiency and semi-transparency of the perovskite solar cells.Further, their charge carrier mobility, defect density, doping concentration, and impact of temperature were investigated.The best-simulated result of SnO2/MAPbBr3/CuI with open circuit voltage (Voc) of 1.59 V, short circuit density (Jsc) of 2.5 mA/cm 2 , fill factor (F.F) of 86.25%, PCE of 7.59% and AVT 20.2%.
