This paper created excellent photo-anode materials based on Fe2CuO4 Nanoparticles to efficiently convert the photoelectric into a dye-sensitized solar cell (DSSC). The Fe2CuO4 nanoparticles were prepared via the UV-Irradiation method. The synthesized nanoparticles morphology structure and optical properties were examined using various X-ray diffraction (XRD), Energy Dispersive X-Ray Analysis (EDX) / mapping, field emission scanning electron microscope (FE-SEM), Transmission Electron Microscopy (TEM), and photoluminescence spectroscopy (PL) are examples of these techniques. Transmission electron microscopes (TEM) images validated the Field emission scanning electron microscopy (FE-SEM) and crystal structure of the generated Fe2CuO4 NPs, which had an average particle size of (11.7 nm), and the X-ray diffraction analysis (XRD) investigation indicated no impurity peaks. Photoluminescence spectroscopy (PL) was used to examine the optical characteristics, and the energy gap was found to be 1.95 eV. Nano-powder has been used to develop a successful photo-sensitizing solar cell employing cibacron brilliant red b as a photosensitizer with an efficiency of about 6.47 to 10.39 % energy conversion. We have created a time-saving technology that is simple to regulate, which makes it possible to produce nano-particulate composites without a high testing need. Our findings could investigate an opportunity for nanomaterials to be synthesized with highly rapid answers and now photoanode.

In this project, we report on the prepare of nickel oxide nanoparticles (NiO NPs) via a photolysis method using UV lamb followed by calcination at 400 C for 3 h. the synthesized Nano-powder were investigated field emission scanning electron microscope (FE-SEM), photoluminescence spectroscopy (PL) and X-ray diffraction (XRD). The SEM image confirmed the crystal structure of the synthesized NiO nanoparticles with an average particle size of 23 nm, and the XRD analysis revealed the absence of impurity peaks. The optical properties were analyzed using photoluminescence spectroscopy (PL), and the bandgap was determined to be 3.4 eV. The semiconductor property, which can be exploited for solar cell applications, is responsible for the broad bandgap. To make dyesensitized solar cells (DSSC), we used photo-chemically synthesized NiO NPs as a photoanode. Two counter electrode were used in this study: Graphene oxide Nano-Sheets and Graphene oxide\silver nanocomposite. cibacron brilliant red B is one of the dyes that are used in the textile factory of Wasit Governorate, and the rest of it is often discarded as waste water Which we used in our study as a photosensitizer. The open-circuit voltage (Voc), short t current density (Jsc), fill factor (FF), and efficiency (h) were determined from the J-V curves, where efficiency was between 0.231 to 1.47 %, at 100 mW/cm2. Finally, it can be confirmed that the presence of nickel oxide nanoparticles with a cibacron brilliant red B dye can improve the performance of dye-sensitized solar cells.
