Abstract
Semiconducting materials are important for emerging electronic and photovoltaic technologies because their structural, optical and electrical properties can be tailored for specific device applications. In this study, a TiO₂-based composite photoanode is considered as a polymer-assisted semiconducting thin-film system in which inorganic TiO₂ nanoparticles are processed with organic film-forming components to produce a porous layer for dye-sensitised solar cell application. Nanocrystalline TiO₂ nanoparticles were synthesised from titanium isopropoxide using a hydrothermal method in an ethanol/deionised water medium. The nanoparticles were converted into a paste using ethyl cellulose and α-terpineol and coated onto fluorine-doped tin oxide glass substrates by the doctor-blade technique. Dye-sensitised solar cells were fabricated using TiO₂ films with thicknesses of 10, 12, 14 and 18 µm, N-719 dye, a platinum counter electrode and an iodide-based electrolyte. X-ray diffraction confirmed the formation of anatase TiO₂, while scanning electron microscopy and transmission electron microscopy showed nanoscale particles with porous and aggregated morphology. Photovoltaic measurements under simulated sunlight showed that film thickness strongly influenced dye adsorption, light harvesting, charge transport and recombination. The highest efficiency of 2.55% was obtained for the 14 µm TiO₂ film. The 18 µm film showed lower efficiency because of reduced transparency and increased recombination. These findings demonstrate that thickness optimisation of polymer-assisted TiO₂ composite photoanodes can improve DSSC performance and support the development of semiconductor composite films for photovoltaic and emerging electronic applications.
Keywords: Semiconducting materials, nanocrystalline TiO₂, polymer-assisted thin films, composite photoanode, dye-sensitised solar cells, photovoltaic applications, emerging electronics.
