Performance Optimization Of Perovskite Solar Cells With All Inorganic Charge-Selective Layers

Recently-Organic-Inorganic solar cells have been realized as emerging materials can be immediately deposited by various materials device architecture,fabrication processes and performance optimization have improved the Photovoltaic parameters,due to rapidly progress in power conversion efficiency.ease of processing,and relatively low cost production among other materials.The high transmittance,high hole mobility,and high chemical stability,of inorganic p-type semiconductor are specifically are of great interest.In order to understand the behavior and performance optimization of perovskite solar cells(PSCs),a numerical simulation adopted through a solar simulation program wxAMPS,which is updated version of AMPS(Analysis of Microelectronic and Photonics Structure).We evaluated new techniques and an architecture based on the perovskite configuration of NiO@Zn/CH3NH3Pbl3/ZnO/Al integrated with stable and low-cost NiO hole-transporting material with composite of Zn,ZnO electron-transporting material,and Al counter electrode has been modeled as a planar PSC and studied theoretically.The feasibility of five different HTMs including spiro-OMeTAD.Cu2O,CuSCN,NiO.Cul and NiO(@Zn have been compared in parametrical studies.NiO@Zn is amongst them the most promising candidate with a theoretical efficiency limit of up to 24%.This study aims to provide better understanding of the role of each component in solar cell and their interfacial interaction.Meanwhile,the performance of solar cell could be influence in an effective way by the bandgap of active materials,defect density and operating temperature of model solar cell.After optimization of different parameters involve,highest power-conversion efficiency has been achieved.Herein,theoretical study was done by using one dimensional software program(wxAMPS)to identify the optimal conditions of device operation.This software has been extensively used to derive continuity and Poisson equations from first principles,simulation of carrier transport in solid-state devices and to analyze the transport behavior of perovskite device structures.From the simulation output,solar cell parameters such as current-voltage characteristics in the dark and,if desired,under illumination can be obtained.This theoretical study is providing better understanding at improve the design of PSCs,based on n-type HTL with p-type composite which are highly efficient,stable,and economical to fabricate.
