In this paper,ordered one-dimensional poly(3-hexylthiophene)(P3HT)/CdS/TiO2/ZnO core-shell nanorod arrays were fabricated.Highly ordered and vertically oriented one-dimensional ZnO nanorod arrays were electrodeposited on the indium-tin oxide(ITO) glass substrates.TiO2 sol was deposited on ZnO nanorod array by dip-coating to obtain TiO2/ZnO core-shell nanorod array.CdS nanocrystals were electrodeposited on the TiO2/ZnO core-shell nanorods to fabricate CdS/TiO2/ZnO core-shell nanorod arrays.Then a thin P3HT layer was electrodeposited on the CdS/TiO2/ZnO core-shell nanorod arrays to prepare the photoanode of the nanostructured hybrid solar cell.The photovoltaic performance of the hybrid solar cell was tested,and the mechanism of the solar cell was investigated.
