    摘要: Another aspect of the present disclosure relates to a device including a substrate, having a top surface and a bottom surface; an array of nanowires having a base and a top surface, the base contacting the top surface of the substrate; a contacting structure including the same material as the substrate having a non-nanostructured surface of a dimension suitable for forming an electrical contact, located on the same side of the substrate as the array of silicon nanowires; wherein the contacting structure is doped with a greater impurity concentration than the nanowire array, thereby forming a selective emitter.

    摘要: In an aspect of the invention, a process to make a nanowire array is provided. In the process, silicon is deposited onto a conductive substrate comprising an organic material and optionally a conductive layer, thus forming a silicon-containing layer. Nanoparticles are deposited on top of the silicon-containing layer. Metal is deposited on top of the nanoparticles and silicon in such a way that the metal is present and touches silicon where etching is desired and is blocked from touching silicon or not present elsewhere. The metallized substrate is contacted with an etchant aqueous solution comprising about 2 to about 49 weight percent HF and an oxidizing agent.
