A simple hydrothermal method was employed to synthesize various aspect ratio zinc oxide nanorods. These nanorods were incorporated into a conducting polymer, poly (9-vinylcarbazole). A series of hybrid bulk heterojunction solar cells was fabricated by using nanocomposite material as the active layer. Short circuit current density of the devices increases from 1.075 mAcm(-2) to 28.35 mAcm(-2) by increasing the aspect ratio, due to the formation of large number of charges and more percolation pathways facilitating the transport of electrons. Photo conversion efficiency of the devices was increased from 0.05 to 0.44% with increase in the aspect ratio from 8 to 20.
