Dispersion Relation Due to the Interaction of the Atoms of Titanium and Oxygen Owing to Electron Trapping by the Anode (TiO2) of a Dye-sensitized Solar Cell

E.L. Efurumibe, A.D. Asiegbu and M.U. Onuu    

Abstract: Titanium dioxide is an important raw material for the fabrication of the anode of a dye-sensitized solar cell. The fact it that electrons are trapped within this anode as they flow through it. These trapped electrons tend to set the atoms of titanium dioxide into vibration. Here this vibration (interaction) has been investigated. The aim of the research was to generate the dispersion relation owing to the interaction between the atoms of titanium and oxygen in a unit cell of the crystal of TiO2. Certain assumptions were made before formulation the mathematical mode that generated the dispersion relation. The result showed a dispersion relation at various angular steps.
