Description
Summary:Foam-like zinc orthotitanate (Zn sub(2)TiO sub(4)) is successfully synthesized viathe wet chemical sol-gel route assisted with a structure-directing diblock copolymer template. The wet chemical route enables spray deposition of Zn sub(2)TiO sub(4) films. Calcination temperature of the spray-deposited films is shown to be crucial for the synthesis of the compound phase, Zn sub(2)TiO sub(4). Surface composition and optical properties of the films are also studied. Finally, Zn sub(2)TiO sub(4) films are shown to offer a reasonable functioning as an electron acceptor in dye-sensitized solar cells, with the best preliminary performance reported so far.
