METHOD FOR PREPARING CONDUCTIVE AND TRANSPARENT LAYERS OF ALUMINIUM-DOPED ZINC OXIDE

摘要

The invention relates to a method for preparing conductive and transparent layers of aluminium-doped zinc oxide (AZO) by means of electrodeposition, where the electrolyte comprises at least an ionic liquid, a source of oxygen, a source of aluminium and a source of zinc, the concentration of zinc in the electrolyte remaining between 5x10^-5 M and 0.5 M during the process, the concentration of aluminium in the electrolyte being between 1x10^-3 % and 10 % in an atomic proportion in relation to the concentration of zinc. The process is carried out at a temperature of between 0° and 250°C. The layers obtained can be used in photovoltaic technology as transparent and conductive oxide layers that form the front contact of a photovoltaic cell.
