Characteristics of Nanostructured TiO₂ Prepared by One-Step Soaking Method for Photovoltaic Application

Abstract:

Nanostructured TiO₂ films were prepared by a one-step soaking method, which has many advantages, such as simple fabrication, a short reaction time, and fast growth. We have investigated the growth of TiO₂ films by the substrate orientation of the soaking method, which had an effect on the nanostructure of the TiO₂ films. The TiO₂ films prepared by this method had various structures: particulate-flat structure and sphere-flat structure. To determine the effect of the nanostructure of TiO₂ films on the photovoltaic characteristics of solar cells, solar cell devices using the inorganic semiconductor Sb₂S₃ as a sensitizer were fabricated by chemical bath deposition (CBD). Our solar cell device, using TiO₂ film with a sphere-flat structure as a photoelectrode, exhibited J_SC, V_OC, FF, and η values of 11.82 mA / cm², 0.49 V, 30.27 %, and 1.74 %, respectively.
