ZnO nanobelts as a photoelectrode for dye-sensitized solar cell

ZnO nanobelts layer of the dye-sensitized solar cell were prepared by RF sputtered ZnO target onto a copper substrate and characterized by FE-SEM. The structures of solar cells based on ZnO as a photoelectrode, Eosin-Y as a dye sensitizer, iodine/iodide solution as an electrolyte and Pt/TCO as a cou...
