摘要: A process is provided for contacting a nanostructured surface. The process may include (a) providing a substrate having a nanostructured material on a surface, (b) passivating the surface on which the nanostructured material is located, (c) screen printing onto the nanostructured surface and (d) firing the screen printing ink at a high temperature. In some embodiments, the nanostructured material compromises silicon. In some embodiments, the nanostructured material includes silicon nanowires. In some embodiments, the nanowires are around 150 nm, 250 nm, or 400 nm in length. In some embodiments, the nanowires have a diameter range between about 30 nm and about 200 nm. In some embodiments, the nanowires are tapered such that the base is larger than the tip. In some embodiments, the nanowires are tapered at an angle of about 1 degree, about 3 degrees, or about 10 degrees. In some embodiments, a high temperature can be approximately 700C, 750C, 800C, or 850C.

摘要: In an aspect of this disclosure, a method is provided comprising the steps of: (a) providing a silicon-containing substrate, (b) depositing a first metal on the substrate, (c) etching the substrate produced by step (b) using a first etch, and (d) etching the substrate produced by step (c) using a second etch, wherein the second etch is more aggressive towards the deposited metal than the first etch, wherein the result of step (d) comprises silicon nanowires. The method may further comprise, for example, steps (b1) subjecting the first metal to a treatment which causes it to agglomerate and (b2) depositing a second metal.
