Abstract
Perovskite-based solar cell technologies have sparked much interest in recent decades. A solar cell’s efficiency is an essential factor in developing a highly efficient device. The power conversion efficiency (PCE) of Perovskite-based solar cells can be enhanced by adding new materials to the photon-absorbing layer and altering the electron and hole transport layers. Titanium dioxide (TiO2) is commonly used in electron transport layers (ETLs), but it has been shown that replacing TiO2 with molybdenum trioxide (MoO3) improves PCE. We use the OghmaNano software to simulate a perovskite-based solar cell and investigate the PCE for TiO2 and MoO3 ETL layers by altering their thickness. The influence of electron and hole drift diffusion, carrier continuity equations in the position space to describe charge flow within the device, Poisson’s equation, and charge carrier recombination have all been investigated in the context of solar cell simulation. It was observed that by substituting the ETL layer of TiO2 with MoO3 in the device, the PCE significantly increases.
