ZnO nanostructures coated Cu (Copper) have been successfully grown using a method of seed mediated hydrotermal. The growth of Cu coated ZnO nanostructures were used as an active material of DSSC. The Cu on ZnO nanostructures has been coated at a concentration of 10 mM at room temperature in 30 minutes. The samples were characterized using Field Emission Scanning Electron Microscope (FESEM), Energy Dispersive X-ray (EDX). The FESEM images showed that the geometrical shape of ZnO nanostructures was nanoflower. Spectra of EDX showed Cu was really exist in all samplesof about 0.8%. A DSSC was fabricated by using the ZnO nanostructured coated Cu as an active material.The results of I-V measurements under iluminattion of halogen lamp its intensity of 100 mW/cm2 has produced efficiency 0.35% (DSSC without copper) and increasedto 0,43% whenCuwas coated on ZnO.

The electrical and optical properties of nanomaterials depend on their structural form. As an effort to develop an advanced nanomaterial, zinc oxide (ZnO) is interesting to synthesis for many applications such as active material for solar cells and biosensors. This paper provides the role of palladium and plasmonic materials in growing ZnO nanostructure, with a focus on its structural analysis. Nanomaterial ZnO was grown by seed-mediated hydrothermal method with layering by plasmonic materials, i.e. gold (Au) and platinum (Ag). X-ray diffraction analysis shows the presence of three dominant peak angles, i.e 34.43o, 36.32o, and 47.49o corresponding to crystal orientation of (002), (101) and (102), respectively. Palladium (Pd) treatment plus layering by plasmonic materials give a higher size of the nanostructure, but their electric band gaps are decreasing slightly. These findings also supported by high absorbance in UV-vis spectra. Gold layering on the nanomaterial gives a more significant role than platinum which indicated by higher size in diameter and higher absorption of UV-Vis spectra. The average size of pristine ZnO, ZnO:Pd, ZnO:Pd:Ag, and ZnO:Pd:Ag are 44.13, 45.99, 45.28, and 44.81 nm, respectively.

We provide a preliminary study of ZnO nanostructure synthesis by coating aluminium and metallic plasmonic Au-Ag using seed mediated hydrothermal method. The growth process is carried out on the FTO substrate and characterized using UV-Vis, XRD, FESEM and EDX spectrophotometer system. The UV-Vis spectrum shows that strong absorption occurs at wavelengths around 370 nm, for all samples. The XRD pattern shows three diffraction peaks at angles 2θ = 34.43°, 36.32° and 47.49°. Each peak corresponds to the crystal fields of (100), (002) and (101). Morphology of the samples shows the presence of ZnO nanorod. A compact and denser nanostructure also obtained.
