We report a simple, versatile, two-step fabrication technique for synthesizing a core-shell nanorod array whose architecture is specifically suited for use as an electrode in a dye sensitized solar cell (DSSC). The particular structure fabricated by us consists of a parallel array of 5 mu m long and 150-200 nm wide Ag nanorod cores, each coated with a 15-20 nm thick ZnO shell. Importantly, the shell thickness is roughly uniform throughout the length of the rods, which are free standing but distinctly separated from each other. This would allow the dye to penetrate freely and cover the ZnO surface completely in a DSSC. (C) 2010 Elsevier B.V. All rights reserved.
