Performance Simulation of Perovskite Solar Cell With Ti3C2Tx Mxene as the Htl
Abstract
Lately, the use of 2D transitional metal carbides (MXene) in perovskite solar cells (PSC) due to their favorable properties like high carrier mobility, high electrical conductivity and tunable work function, has gained significant attention. The use of Ti 3 C 2 T _x_ as HTL in perovskite experimentally has been reported. In this work, a simulation of perovskite solar cell incorporating Ti 3 C 2 T _x_ MXene as hole transport layer (HTL) using SCAPS1D software has been presented. A numerical investigation of the effect of ETL, HTL, and absorber doping concentration; absorber defect density; absorber/ETL and absorber/HTL interface defect density, and HTL thickness on the device photovoltaic performance has been explored. After optimization, the metric parameters obtained were; VOC = 0.9287 V, JSC = 21.43 mA/cm^2 , FF = 70.90 % and PCE = 14.11%. Comparing the simulated and experimental results reported shows that optimizing the MXene thickness, doping concentrations and defect densities improves the device’s photovoltaic performance.
