The effect of hydroxyl on dye-sensitized solar cells assembled with TiO2 nanorods
Meng, Lijian; Yang, Tao; Yun, Sining; Li, CanTiO2 nanorods have been prepared on ITO substrates by dc reactive magnetron sputtering technique. The hydroxyl groups have been introduced on the nanorods surface. The structure and the optical properties of these nanorods have been studied. The dye-sensitized solar cells (DSSCs) have been assembled using these TiO2 nanorods as photoelectrode. And the effect of the hydroxyl groups on the properties of the photo...
One-step preparation of optically transparent Ni-Fe oxide film electrocatalyst ...
Zhang, Doudou; Meng, Lijian; Shi, jingying; Wang, Nan; Liu, Shengzhong; Li, CanOptically transparent cocatalyst film materials is very desirable for improved photoelectrochemical (PEC)oxygen evolution reaction (OER) over light harvesting photoelectrodes which require the exciting light to irradiate through the cocatalyst side, i.e., front-side illumination. In view of the reaction overpotential at electrode/electrolyte interface, the OER electrocatalysts have been extensively used as coca...
Preparation and characterization of dye-sensitized TiO2 nanorod solar cells
Meng, Lijian; Chen, Hong; Li, Can; Santos, M.P. dosTiO2 nanorodswere prepared by DC reactive magnetron sputtering technique and applied to dye-sensitized solar cells (DSSCs). The length of the TiO2 nanorods was varied from 1 μm to 6 μm. The scanning electronmicroscopy images showthat the nanorods are perpendicular to the substrate. Both the X-ray diffraction patterns and Raman scattering results show that the nanorods have an anatase phase; no other phase has b...

Meng, Lijian; Chen, Hong; Li, Can; Dos Santos, Manuel PereiraTiO2 films have been deposited on ITO substrates by DC reactive magnetron sputtering technique. It has been found that the sputtering pressure is a very important parameter for the structure of the deposited TiO2 films. When the pressure is lower than 1 Pa, the deposited film has a dense structure and shows a preferred orientation along the [101] direction. However, the nanorod structure has been obtained as th...

Structural Modification of TiO2 Nanorod Films with an Influence on the Photovol...
Meng, Lijian; Li, Can; Dos Santos, M.P.TiO2 nanorod films have been deposited on ITO substrates by dc reactive magnetron sputtering technique. The structures of these nanorod films were modified by the variation of the oxygen pressure during the sputtering process. Although all these TiO2 nanorod films deposited at different oxygen pressures show an anatase structure, the orientation of the nanorod films varies with the oxygen pressure. Only a very ...

Zhao, Ji; Li, Jun; Ying, Pinliang; Zhang, Wenhua; Meng, Lijian; Li, CanThis communication presents a novel kind of silicon nanomaterial: freestanding Si nanowire arrays (Si NWAs), which are synthesized facilely by one-step template-free electro-deoxidation of SiO2 in molten CaCl2. The self-assembling growth process of this material is also investigated preliminarily.
