In this study, a theoretical model was presented to calculate current and current density to investigate the efficiency of the heterogeneous ruthenium 620-TiO2 device using a propanol solvent. This work examines the effect of concentration carriers on the current density and performance of ruthenium 620-TiO2 devices for dye-sensitized solar cells (DSSCs) in the presence of […]
Titanium dioxide (TiO2) nanoparticles (NPs) were synthesized by a simple sol-gel technique. The prepared sample was characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), and Brunauer–Emmett–Teller (BET). The results showed that the prepared TiO2 NPs have agglomerated spherical shapes with anatase and rutile phases, […]
