Abstract:

In today's world, the utilization of clean energy has become imperative, to meet this demand, humanity has long tapped into inexhaustible energy resources. Among these, harnessing energy from solar radiation through solar cells stands out as a prominent example.  Regarding solar energy, Perovskite Solar Cells (PSCs) devices have been a revolution in this field. The reason behind their popularity is their performance. In just ten years, their performance efficiency increased at a quick pace. In comparison to traditional silicon-based Solar Cells (SC), PSCs have higher tunability and lower fabrication costs. PSCs can be constructed using either n-i-p or p-i-n configurations. Here, 'n' stands for  ‘Electron Transport Layer (ETL)’, 'p' stands for ‘Hole Transport Layer (HTL)’, and 'i' shows the active material layer, which is positioned between the ETL and HTL. In the current study, TiO2 is employed as the ETL, NiO serves as the HTL, and perovskite is utilized as the active layer. Here, titanium tetra isopropoxide precursor solution serves the purpose in the investigation for developing films of unadulterated TiO2 and F - TiO2 using the sol-gel followed by a spin coating process, different concentrations of F-doped TiO2. The produced film is characterized using a range of techniques, including XRD and SEM, to ascertain its structural properties and surface morphology. The electrical properties were evaluated to determine the current density and voltage using a solar simulator, which subsequently facilitated the calculation of device performance. XRD analysis confirmed the crystalline nature and particle size. Scanning Electron Microscopy SEM images revealed distinct layers, clearly indicating proper deposition of all layers. Electrical measurements demonstrated that the concentration of fluorine doping significantly affects the performance of the device. The PCE (Power Conversion Efficiency) of the fluorine-doped samples is much more impressive than that of the unadulterated samples in the context of the obtained results.
