This study explores the synthesis of S-TiO2 and FeTiO3 nanoparticles using novel method and precursor sources. S-TiO2 nanoparticles are obtained from rutile sand through acid extraction and hydrolysis, while FeTiO3 nanoparticles are obtained from ilmenite sand through acid extraction and hydrolysis. A novel approach involves synthesizing S-TiO2 and FeTiO3 nanoparticles simultaneously using titanium iso-propoxide, sulfuric acid, and thiourea as chemical precursors. The optimization process involves forming titania paste for dye-sensitized solar cells (DSSCs), which are then fabricated using the optimized photoanode structure and widely studied electrolytes with a platinum counter electrode. The devices are tested and evaluated, yielding an impressive ~5% efficiency.
