The effect of UV irradiation on ZnO thin film based gas sensor was investigated. Zinc oxide thin films were deposited on an alkali free glass substrate by magnetron sputtering system using zinc target. The UV irradiation of the ZnO thin films was measured to understand the change of microstructure, electrical properties, optical properties and gas sensing characteristics. The X-ray diffraction patterns...
Successive ionic layer adsorption and reaction technique (SILAR) and solution growth technique have been applied to deposit thin films on amorphous glass substrates. Various parameters, like concentration of complexing agent, pH of the solution, deposition temperature, time, have been optimized to achieve good quality films. Films grown by SILAR method have been found to be non-uniform as confirmed...
Improvement of dye sensitized solar cell was investigated using methyl-violet dye and nanocrystalline ZnO thin film electrodes. A low cost fabrication method and low cost materials were used to prepare this photocell. The X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the microstructure and surface properties of dye coated ZnO electrodes. According to the...
