Numerical Simulation of Lead-Free Perovskite Using TiO2 and MgCuCrO2 as Charge Transport Material

In this paper, we conduct a comprehensive theoretical investigation aimed at identifying the factors limiting efficiency in lead-free double perovskite solar cells. Our study has two main objectives: first, to assess the impact of various parameters on cell performance, and second, to optimize the cell configuration to enhance efficiency. Using a double perovskite as the absorber layer, TiO₂ as the electron transport layer, and MgCuCrO₂ as the hole transport layer, using SCAPS 1D we analyzed the effect of Na and Nd doping on the cell's electrical parameters. The optimized cell structure achieved improved results, demonstrating its potential for lead-free photovoltaic applications and offering insights for future performance enhancement Voc of 1.496V,Jsc of 19.04mA/cm2 FF of 67.37% PCE of 19.2%.
