Abstract
This work deals with the growth investigation of the methylammonium lead triiodide (MAPbI3) thin films prepared by the spin coating technique. Firstly, MAPbI3 films were studied by X-ray diffraction (XRD) and scanning electron microscopy (SEM) and UV-Visible spectroscopy as well as photoluminescence techniques are used to calculate the band gap energy. Indeed, the high-quality MAPbI3 perovskite films were obtained by using Chlorobenzene as an antisolvent with good crystallinity, large grain sizes, and higher absorption compared to MAPbI3 treated by toluene. Secondly, the performance of FTO/TiO2/MAPbI3/Spiro OMeTAD/Au perovskite solar cell was evaluated using a numerical simulation of the Solar Cell by SCAPS simulator. The effect of the structural and physical parameters of MAPbI3 absorber layer and HTL with the different antisolvents, including thickness, defect density, total charge density, donor density and electron affinity. Obtained results are: Jsc of 25.96 mA/cm2, PCE of 30.70%, Voc of 1.259 V, FF of 88.93% of MAPbI3-based solar cells when MAPbI3 is treated by toluene. However, for MAPbI3- Chlorobenzene, the I-V characteristics are rather: Jsc of 28.18 mA/cm2, PCE of 31.81%, FF of 88.19% and Voc of 1.200 V. It is pointed out that the use of chlorobenzene may be of interest to improve the perovskites solar cells performances.
