Nickel oxide nanofibers manufactured via sol-gel method: synthesis, characterization and use it as a photo-anode in the dye sensitized solar cell

Abstract

A modified method with sol-gel nickel oxide (NiO) nano fibers was used for current research synthesized. FE‐ SEM, AFM,and UV visible spectroscopy were used to investigate the morphology and optic properties of the synthesized nano. The synthesized nickel oxide structure has been demonstrated with X-ray diffraction (XRD),average crystalline size was 10.08 nm while particle size ~23 nm with fiber structure from FE‐ SEM and 16.87 nm from AFM. Nanofiber was used to produce a new solar cell (ITO/ NiO/ Rhodamina 6 G/iodide/Al nanofilm/ITO) with a photo-sensitization of approximately 0.973%.

“…Nanotechnology is a significant advancement in modern science that enables the fabrication of materials with distinct size, structure, and substance [1][2][3][4][5][6][7][8][9]. These nano dimensions materials (with sizes ranging from 1 to 100 nm) are hypothesized to operate as a link between atomic and bulk materials, exhibiting a wide range of chemical, physical, and electrical properties [10][11][12][13][14].…”

of Fe2O3Nanoparticles By Photolysis Method For Novel Dye-sensitized Solar Cell

“…Thin sheets of wide band gap semiconductors, photosensitizers (dye), redox couple, and platinum counter electrode are used to make dye-sensitized solar cells (DSSCs) [15]. During the cyclic reaction of DSSC operation, no net chemical changes occur; only light energy is converted into electrical energy [16,17]. In comparison to the quantity of nanoparticles produced naturally or accidentally, nanoparticles synthesized for research or industrial purposes are a small minority.…”

“…In comparison to the quantity of nanoparticles produced naturally or accidentally, nanoparticles synthesized for research or industrial purposes are a small minority. Iron oxide nanoparticles are an essential oxide, with many applications due to their non-toxicity [18][19][20][21][22]. There are many forms of iron oxide crystalline phases: Hematite α-Fe2O3, β-Fe2O3, Maghemite γ-Fe2O3, Epsilon Fe2O3 and Magnetite (Fe3O4).…”

“…Diverse new and alternatives with all primary elements of a dye sensitized solar cell, including the working electrode, which is made up of semiconductor nanoparticles infused with sensitizer dye, a redox electrolyte, and the counter electrode, have been developed and tested in order to make these cells more efficient and cost effective. The use of nanotechnology in biological systems is a branch of biology and nanotechnology [5]. The creation of biocompatible, ecologically friendly, and biogenic nanomaterials and nanoparticles is also a part of nanotechnology [6].…”

“…Environmental research, electrochemistry, biology, chemical sensing, magnetism, and other fields all use metal oxides [15]. Iron oxide nanoparticles is one of the important oxides, which has many applications due to its' non-toxicity [16][17][18][19][20]. There are many forms of iron oxide crystalline phases, which include: Hematite α-Fe2O3, β-Fe2O3, Maghemite γ-Fe2O3, Epsilon Fe2O3 and Magnetite (Fe3O4) [21][22][23].…”
