According to reports, a unique method to improve the efficiency of titanium dioxide (TiO 2) dye-sensitized solar cells (DSSCs) involves inserting foreign ions into the material’s lattice structure before forming the heterostructure. The sol–gel technique has been used to produce films of TiO 2, Cr–TiO 2, TiO 2@Cr–TiO 2, and Cr–TiO 2@TiO 2. A small quantity of rutile phase with the anatase phase was observed in heterostructures, and XRD validated the anatase phase of pure Cr–TiO 2@TiO 2, which contains a large grain size (46 nm). SEM presents numerous well-formed, homogenous grains in the structure of Cr–TiO 2@ TiO 2, providing a large surface area for dye loading in DSSCs. Among all samples, Cr–TiO 2@TiO 2 exhibits a small band gap (Eg) (3.2 eV), and high transmittance in the visible spectrum has been observed by UV–Vis spectroscopy. The Cr–TiO 2@ TiO 2 cell demonstrates high Jsc (7.69 mA-cm −2), Voc (0.79 V), and effi ciency (4.57%). The small recombination resistance, verifi ed from EIS, is responsible for this high efficiency.
