Anodised Aluminium

AbstractAnodised aluminium oxide films have several applications in nanotechnology due to the ability to control the dimensions and ordering of the pores. Several techniques have been developed which allow for accurate control over the ordering of pore arrays. Examples of such techniques are the “Two-Step” method, and embossing with optical gratings or micro-machined Si templates. It will be demonstrated that it is possible to control the position of the pores using a nanoindenting device that has scratched the aluminium surface before anodising. The interpore distances accomplished via this technique were 200nm and 400nm by anodising in 0.3M (COOH)2 at 80V and 0.1M H3PO4 at 160V respectively. Hexagonal and square arrays were created by scratching the aluminium with a series of crosshatched lines.

Anodised Aluminium

ABSTRACTHigher silicon solar efficiencies are possible if metal contact is made to the cell though openings in a well-passivated surface. Patterning for rear point-contact schemes has typically been achieved using deterministic patterning methods involving either the use of photolithography, laser or inkjet patterning. However, with these approaches it is difficult to achieve cost-effective, high-throughput and robust processing if very small and closely-spaced openings are required. In this paper we review recent progress in the use of self-patterning anodised aluminium oxide layers to both passivate and enable point metal contacts to the rear surface of silicon solar cells. We describe a wet chemical method for anodising aluminium layers thermally-evaporated on the rear surfaces of silicon solar cells, and demonstrate that the layers can result in excellent passivation of the underlying silicon and also enable metal contact to the solar cell. Additionally, we describe how patterning of either the anodic aluminium oxide layer or the source aluminium layer can result in patterns of metallic and dielectric regions on a surface, and how currently-available solar cell electroplating tools can be adapted to achieve anodisation of solar cells at commercial processing throughput rates.

AbstractEnergy dispersive X-ray spectroscopy and scanning electron microscopy were used to analyse nickel on anodic aluminium surfaces after stripping the anodic aluminium oxide. The metal was electroplated at the bottom of the pores of anodised aluminium during electrolytic colouring in solutions without (Watts) and with (citrate) complexing agents, respectively. A relation between the anodic-cathodic processes, changes of the structure and composition of the coating in dependence on the used solution were studied. A morphology study performed after stripping the anodic aluminium oxide revealed the crucial influence of the anodic process/cycle and the complexing agent on the nickel structure on the aluminium surface. Off-time of half-way rectified current influenced the nickel deposition in the pores of anodic alumina negatively.
