摘要： Methods for light-induced electroplating of aluminum are disclosed herein. Exemplary methods may comprise preparing an ionic liquid comprising aluminum chloride (AlCl3) and an organic halide, placing the silicon substrate into the ionic liquid, illuminating the silicon substrate, the illumination passing through the ionic liquid, and depositing aluminum onto the silicon substrate via a light-induced electroplating process, wherein the light-induced electroplating process utilizes an applied current that does not exceed a photo-generated current generated by the illumination.

摘要： An electrochemical-deposition apparatus includes an electrode array, a photoconductor, an electrically conductive layer, an electromagnetic-radiation emitter, an electric-power source, and a controller. The controller is configured to direct electric power to be supplied from the electric-power source to the electrically conductive layer and direct the electromagnetic-radiation emitter to generate electromagnetic radiation. When the electric power is supplied to the electrically conductive layer and when the electromagnetic radiation is generated, the photoconductor is illuminated at a first radiation level and a first level of electric current is enabled through the photoconductor and the at least one deposition electrode. When the electric power is supplied to the electrically conductive layer and when the electromagnetic radiation is generated, the photoconductor is illuminated at a second radiation level and a second level of electric current is enabled through the photoconductor and the at least one deposition electrode.
