Abstract:

CdSe nanorods arrays were grown on ITO substrate by electrochemical deposition method at room temperature. Using Xray diffraction (XRD), energy dispersive Xray (EDX), field emission scanning electron microscopy (FESEM) and UVVis absorption spectroscopy, we characterized the CdSe nanorods
array, and studied its photoelectric chemical properties. We tested the photoelectric properties of CdSe nanorods array electrodes under the standard three electrode system. The results show that the sample is preferentially grown along \[001\] direction, and has obvious light response properties. When the light intensity is 100 mW/cm², the optical current density (J_sc), open circuit voltage (V_oc), the fill factor (FF) are 2.93 mA/cm², 116 V, 0278, and the photoelectric conversion efficiency of the battery η=0.947%.

Key words: CdSe nanorod, electrochemical deposition, photoelectric chemical property
