Effect of hydroxyl on dye-sensitized solar cells assembled with TiO ₂ nanorods

Abstract

TiO 2 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 TiO 2 nanorods as photoelectrode. And the effect of the hydroxyl groups on the properties of the photoelectric conversion of the DSSCs has been studied.

A water coordinated Ni complex and a 2D Ni-MOF: topology dependent highly enhanced electrocatalytic OER activity

“…The peak that appeared at 535.78 eV might be attributed to the adsorbed water molecule. 57 The higher binding energy of Ni 2+ and the O 1s peak suggested the generation of nickel hydroxides/oxyhydroxides during electrocatalysis. 58,59 The peak at 530.3 of O 1s might be due to the higher number of oxygen vacancies.…”
