Abstract

Semiconductor Zinc Oxide (ZnO) nanoparticles was synthesized by method gel-combustion with solubility variations of citric acid (0.2; 0.3; 0.4) mol/L as fuel and calcination temperature at 500℃ and 700℃ and addition dye sensitizer anthocyanin was extracted from dragon fruit. The composition obtained in the EDS analysis is Zn and O which indicates the formation of ZnO compounds. The surface morphology of ZnO is still agglomerated between particles and has an average size of 816 nm (0.2 mol/L), 555 nm (0.3 mol/L), and 824.5 nm (0.4 mol/L), respectively. The XRD analysis result showed crystal orientation of concentration variation expectively difference, likewise for crystal size distribution and strain orientation was different. The acid citric played important for these case, enhanced concentration caused particle size decreased. The presence of hydroxyl made be weak and polarization ligand bonding in metal-oxygen of Zn-O. The XRD pattern showed diffraction peak a quite similar and wurtzite structure. The result showed lattice strain and crystal size distribution decreased with enhanced addition acid concentration. But the acid 0.3 mol/L presented the smallest crystal size was 27.8 nm. The anthocyanin had given effect not significantly, can be seen in optical result all sample at ultraviolet spectrum region. The absorbance value and wavelength of each sample are different showed absorbance increased with addition citric acid. All samples have the same treatment but the best absorbance and wavelength values at 335 nm, 355 nm and 340 nm, respectively. It obtained sample with 0.3 mol/L very high than another. Furthermore, casting method had to be details in deposition process to produce film which has a wide absorption from UV to visible spectrum region and can be used for solar cell applications dye sensitized solar cell.
