Abstract :
This paper reported the fabrication of CdS nanorod arrays on transparent conductive tin-doped In2O3 (ITO) glass substrate by combining
electrodeposition and hydrothermal processes. One thin layer of CdS particles on substrates was prepared by electrodeposition as
seeds, upon which well-aligned nanorod arrays were hydrothermally grown in large scale. The morphology, structure and phase composition
of CdS nanorod arrays were examined by X-ray diffraction, field-emission scanning electron microscopy, energy-dispersive X-ray
spectroscopy, transmission electron microscopy (TEM), and high-resolution TEM. The optical absorption spectra and the temperaturedependent
photoluminescence of CdS nanorod arrays were also studied. An organic/inorganic hybrid solar cell prototype device was
fabricated based on the as-prepared CdS nanoarrays grown on the transparent ITO electrode (ITO/CdS arrays/poly[2-methoxy-5-(20-ethylhexyloxy)-
1,4-phenylene-vinylene]/Au). The power conversion efficiency was 0.06%, showing an obvious photovoltaic effect.
