Al-Ga co-doped ZnO nanostructures have been successfully grown using seed mediated growth hydrotermal method. The grown of Al-Ga co-doped ZnO nanostructures were used as an active material of DSSC. The growth of ZnO nanostructures has been done by varying percentage of concentration of the Al-Ga co-doped solution, namely Al 0.5, Al 1%, Al 1.5%, Al 2% with Ga 1% and Ga 0.25%, Ga 0.5%, Ga 0.75%, Ga 1%, Ga 1.25%, Ga 1.5% with Al 1% with the growth temperature of 90 °C in 8 hours. The grown ZnO nanostructures were characterized using Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX), X-Ray Diffraction (XRD), and Ultraviolet-Visible Spectroscopy (UV-Vis). The FESEM images showed that the geometrical shape of ZnO nanostructures was nanorod with a hexagonal face shape. The high density and uniformity of particles have been produced from the Al 2% : Ga 1% and Ga 1.25% : Al 1% co-doped ZnO nanorods samples with the length of rods in the range of 210.5 - 531.6 nm and 231.6 - 452.6 nm, respectively. The images of cross-sectional FESEM showed the thickness of about 1.516 - 2.416 μm and 1.682 - 3.316 μm, respectively for co-doped Alv-Gat and Alt-Gav ZnO nanorods. The spectra of EDX showed elemental composition of Al and Ga were really exist in all samples. XRD patterns observed five peaks at 2θ: 31.67o, 34.60o, 36.32o, 47.68o, and 56.60o for Al 2% : Ga 1% co-doped ZnO nanorods and at 2θ: 31.80o, 34.56o, 36.32o, 47.68o, and 56.56o for Ga 1.25% : Al 1% co-doped ZnO nanorods. Analysis of Match! version 2 software confirmed 5 peaks could be indexed to (100), (002), (101), (012), and (110) crystal planes. The UV-Vis spectra of the samples showed that the high peak absorption occured in the wavelength range of 330 - 380 nm. Dye sensitized solar cells was fabricated utilizing Al-Ga co-doped ZnO nanorod as an active material, dye N719, liquid electrolyte, and platisol as a catalyst on the counter electrode. The results of I-V measurements under halogen lamp with ilumination intensity of 100 mW/cm2 of the cells has produced maximum efficiency of 0.398% for 2% : Ga 1% co-doped ZnO nanorods and 0.196% for Al 2% : Ga 1% ZnO co-doped nanorods. This value were much higher than that of pure ZnO nanorods based DSSC.
Keywords: Dye sensitized solar cells, nanorod ZnO, aluminum, gallium, co-doping, seed mediated growth hydrotermal method.
