The studied inverted P-I-N structure is PEDOT:PSS/ CH3NH3PbI3/ PCBM where PEDOT:PSS is the hole transporting layer (HTL), CH3NH3PbI3 is the Perovskite absorber layer (PVK) and PCBM is the electron transporting layer (ETL). The simulated structure is sandwiched between SnO2: FTO and Al which are the transparent and aluminum electrodes respectively. Simulation efforts are focused on thickness and density of states (donor’s and acceptors) effect on solar cell efficiency. Found results improved the power conversion efficiency (PCE) from 11.73% up to 19.58 %.enPerovskite, CH3NH3PbI3, SCAPS, power conversion efficiency, layer thicknessArticle
