| Abstract: | One-dimensional (1D) ZnO nano-rods array was grown by the hydrothermal method. ITO substrates were immersed in equal-molar of zinc nitrate (Zn(NO)(3)center dot 6H(2)O) and methenamine (C(6)H(12)N(4)) aqueous solution at 90 degrees C for 24 h to grow ZnO nano-rods. The reaction solutions with different molar concentrations were used to growth different thickness and diameter of ZnO nano-rods. The shape of ZnO nanorods is hexagonal and the grain size can be changed from 30 nm to 500 nm with the prefer orientation of (002). Finally, ZnO nano-rods films were used as electrode materials to fabricate dye sensitized solar cells (DSSCs). A fill factor of 33.43%, short-circuit current of 11.877 mA/cm(2), open-circuit voltage of 0.486 V and an overall light to electricity conversion efficiency of 1.932% were obtained.
