CdSe and CdTe are composite semiconductor materials used in hybrid solar cell due to their high absorption coefficients. CdSe and CdTe have different band gaps, 1.74 eV and 1.45 eV respectively and then they can absorb solar energy in a wider range of wavelength compare to the silicon solar cell. In this research. CdSe and CdTe nanorods were fabricated using electrochemical deposition in an anodic aluminum oxide template. The electrodeposition behaviors of CdSe and CdTe were investigated using cyclic voltammetric technique. The deposition potentials of CdSe and CdTe were obtained through cyclic voltammetric technique. The effects of Te and Se ion concentration in the electrolyte on the composition of the deposits were investigated to obtain 11 atomic ratio. Structures of layered CdSe/CdTe nanorods were analyzed with FESEM and EDS. (C) 2010 Elsevier B.V. All rights reserved.
