| Abstract | ||
| Perovskite solar cells (PSCs) represent one of the most models of the organic-inorganic solar cells which have achieved a great success in the last years. However, there are some of challenges facing this success such the barrier between the layers' interfaces and the presence of grains that impedes the passage of the charge carriers. Consequently, the aim of this work is to synthesize and characterize passivated peroviskte layers using different passivation techniques for producing treated perovskite solar cells. These treated layers were characterized by scanning electron microscope (SEM), UV-visible spectroscopy, photoluminescence, X-ray diffraction (XRD), Fourier transform infrared (FTIR) and current density-voltage measurements. The optimal performance of the fabricated and passivated PSCs with a structure of FTO/blocking layer/mesoporous layer /TiCl4/methylamonium (MA)PbI3-xClx/chlorobenzene/C had short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF) and efficiency of 20 mA/cm2, 0.56 V, 0.29 and 6.5 %, respectively. | ||
