Positive Effect

Highly efficient and effective porous ZnO nanorod arrays were fabricated by annealing ZnO nanorod arrays grown on a substrate using a simple hydrothermal method. The annealing had a positive effect on the nanorod morphology, structure and optical properties. The porosity was closely related to the annealing temperature. After heating at 450 °C, pores appeared on the nanorods. It was demonstrated that the porosity could be exploited to improve the visible light absorption of ZnO and reduce the bandgap from 3.11 eV to 2.99 eV. A combination of improved charge separation and transport of the heat-treated ZnO thus led to an increase in the photoelectrochemical properties. At an irradiation intensity of 100 mW/cm−2, the photocurrent density of the porous nanorod array was approximately 1.3 mA cm−2 at 1.2 V versus Ag/AgCl, which was five times higher than that of the ZnO nanorods. These results revealed the synthesis of promising porous ZnO nanorods for photoelectrochemical applications.

ABSTRACTWe report on a novel use of nanorod arrays for organic based solar cell devices. A metal foil with copper nanorods attached to the surface was developed by electrodepositing copper from a copper sulfate solution into an anodic alumina oxide (AAO) template that had been coated with a metal on one side. The AAO membrane was dissolved in NaOH leaving behind an aligned array of copper nanorods. This nanorod array was evaluated to explore the possibility of increasing the power conversion efficiency of organic solar cells. Nanorod array characteristics were investigated by focus ion beam, scanning electron microscopy, and x-ray diffraction spectroscopy. A solar cell device was made by applying a polymer layer of poly(2-methoxy-5-(3', 7'-dimethyloctyloxy)-1, 4-phenylene-vinylene) (MDMO-PPV) mixed with 6, 6 phentl-C61-butyl acid-methylester (PCBM) onto the copper nanorod array and sandwiching it with a film of poly(3, 4-ethylenedioxythiophene): poly(styrene-sulfonate) (PEDOT:PSS) applied onto a indium tin oxide coated glass substrate.

ABSTRACTGuided mode resonance was numerically demonstrated in the tapered silicon nitride nanorod arrays on glass substrate. Finite difference time domain technique was employed to investigate the detailed light-matter interaction dynamics and the generation of resonance at femtoseconds. Enhanced electromagnetic (EM) field intensity with enhancement factor of 200∼250 could be achieved. This highly concentrated electromagnetic field could be extended to the nanorod array tips and substrate for higher order resonance modes, which allows future application of this transverse propagating field in optical signal amplification, like fluorescence or Raman enhancement.

Well-aligned ZnO nanorod arrays were used as templates to produce Fe(OH)3nanotube arrays. The as-grown Fe(OH)3nanotube arrays were then used as templates to obtain an FeS2nanorod array. The FeS2nanorod arrays had much better photovoltaic properties than the FeS2nanoparticles due to the high specific area, direct transport pathways and enhanced light harvesting of the nanorod array structure.
