Fabrication of ZnO Rod by Electrodeposition and Its Application to Dye Sensitized Solar Cell

High density of ZnO nanorods were fabricated by electrochemical deposition and subsequent heat treatment. Formation of and ZnO during electrodeposition indicated that the electrodeposition efficiency of ZnO was below 33%. ZnO rod has a preferential (200) growth plane after heat treatment at and the growth rate of ZnO rod was measured to be 0.986 . Dye sensitized solar cell(DSC) showed the efficiency of 0.21% when electrochemically prepared ZnO rod was used as an electrode. It suggests the possible application of ZnO rod structure in the DSC.
