CdSe is one of the composite semiconductor materials used in hybrid solar cell. CdSe nanorods were fabricated using electrochemical deposition in anodic aluminum oxide (AAO) template. CdSe were deposited from CdSO4 and H2SeO3 dissolved aqueous solution by direct current electrochemical deposition. Uniformity of CdSe nanorods were dependent on the diameter and the height of holes in AAO. The current density, current mode, bath composition and temperature were controlled to obtained 1:1 atomic composition of CdSe. CdSe electroplating in AAO is bottom-up filling so we applied direct current is better than others for good uniformity of CdSe nanorods. The optimum conditions to obtain 1:1 atomic compositon of CdSe nanorods are direct current 10mA/cm2, 0.25M CdSO4-5mM H2SeO3 electrolytes at room temperature.
