Perovskite-based solar cells are becoming a subject of interest in photovoltaic research area, owing to their high efficiency, abundance, and low cost. In this work, we report the means to calculate the crucial parameters requested by the industrial community such as Short Circuit Current, Open Circuit Voltage, Quantum Efficiency, and electrical power of a given photovoltaic material from ab-initio calculations. This method opens the ability to master the correlation between synthesis and efficiency of all photovoltaic materials without realizing the photovoltaic device. As example of material, CH3NH3PbI3 perovskite is chosen. Firstly, the density of state and optical dielectric constant were calculated using FLAPW method based on density functional theory principle. From both physical quantities, quantum efficiency, Voc, Jsc, and electrical power were estimated. All computed curves and values were compared to experimental data and discussed in terms of photovoltaic efficiency improvement.

Summary Monte Carlo simulations and the full‐potential linearized augmented plane wave (FP‐LAPW) method in the framework of density functional theory (DFT) are applied to investigate the quantum efficiency, ferroelectric, and photovoltaic properties. We have used the generalized Perdew Burke Ernzerhof gradient approximation (PBE‐GGA) as well as the Becke‐Johnson modified exchange potential (TB‐mBJ) to correct the gap's energy. The gap energy results of 2.5 eV obtained using mBJ are reasonable compared to the available experimental data (2.5 eV). The difference energy ∆E between the magnetic configurations EFM and EAFM of Fe was calculated. The BiFeO3 possesses the insulating ground state and G‐type antiferromagnetic ordering. The value of the magnetic moment was compared with the values obtained using experience and theory. The quantum efficiency (EQE), the short‐circuit current and open circuit voltage are investigated using ab‐initio calculations. The polarization, dielectric susceptibility and hysteresis loops are investigated using the Monte Carlo simulations for several thin films of BiFeO3.
