Abstract
A solar cell includes a plurality of nanowires arranged such that diameters of the nanowires sequentially increase in a first direction along a path of incident light. In a method of forming nanowires, a catalyst layer is formed on a substrate, a plurality of nanoparticles are formed by thermally processing the catalyst layer, and nanowires are grown from the plurality of nanoparticles. The catalyst layer has a thickness that increases in a first direction, and the plurality of nanoparticles have diameters that increase in the first direction.
