Abstract:
The present invention provides a hybrid photovoltaic device that combines a base solar cell [20] of single or multi junction with nanostructures of nanowires or nanotubes p-n junction. The nanowire or nanotube p-n junction structures [22] are fabricated on top of metal collectors from the base solar cell [20] as an additional photovoltaic cell on top of the main cell. This allows full area utilization and subsequently improving the overall efficiency of the device with the capability to absorb and operate at more than one band gap energy. Optionally, additional nanowire arrays [24] could also be formed on the open areas of the base solar cell [20] for light-trapping effect to improve the optical absorption properties of the cell.

Abstract:
The present invention provides a method to fabricate Ni-Co alloy where in this process, electrodeposition of Ni-Co alloy is conducted in a non-aqueous electroplating bath consisting of a mixture of ionic liquid, 1-ethyl-3-methyllimidazolium chloride (EMIC) [20] and organic compound, ethylene glycol (EG) [22] as the solvent together with Ni and Co ions, with the application of a magnetic field parallel to the cathode [24] surface. With application of an external permanent magnetic field parallel to the cathode [24] surface, the rate of transport of Ni and Co ions to the cathode surface is increased, therefore increasing the current density of electrodeposition of Ni-Co alloys. As the magnetic force is stronger for the Co ion compared to Ni ion, there will be an increased transport of Co ion compared to the Ni ion to the cathode surface. This result in higher Co content in the Ni-Co alloy compared to Ni, even when the bath composition ratio of Co is lower than the bath composition of Ni.

The present invention provides the method for fabricating tungsten (24) and tungsten oxide (30) nanowires by selective CVD method process on a handle substrate (20) and insulating layer (22) with silicon nanostructure (28) in the presence tungsten hexafluoride precursor without the need to use of metal catalyst or mixed powder. This method uses an underlying silicon nano-structure material where the nanowires are laterally formed, in-planed with the substrate and also has uniform dimension. Tungsten nanowires fabricated can thereon be converted to tungsten oxides by oxidation or annealing process.
