Hollow sphere TiO2: Synthesis and its application for dye-sensitized solar cells

Year: 2025

Type: article

Abstract: The architecture of semiconductor oxides as the core photoanodes in the dye-sensitized solar cells affecting the energy conversion of the dye-sensitized solar cells (DSSC) has been a slightly neglected parameter. Herein, we study that the morphology of hollow sphere (HS) TiO2 as the semiconductor photoanode of DSSC has proven to result in the power conversion efficiency (PCE) higher than the solid sphere of TiO2, and other morphology such as nanotube, nanowire, and nanorod. Affecting the photocurrent density (Jsc) and PCE, efficient electron transfer was achieved in HS TiO2. The percentage of PCE of DSSC using HS TiO2 semiconductor is also influenced by physical properties such as particle size and shell thickness, which influence the dye-loading capacity, the rate of electron transfer, and the scattering effects in visible light harvesting. This review discusses the synthesis and characterization of HS TiO2 from two different synthesis pathways, the one-pot and two-step synthesis, and the modification of HS TiO2 to improve the efficiency of DSSC.
