Titanium dioxide (TiO2) nanoparticles thin films were prepared by electrostatic spray deposition technique. The effect of the deposition times on properties of TiO2 films was investigated. The characteristics of TiO2 thin films were performed by X-ray diffraction, and Raman spectroscopy. In addition, the TiO2 nanoparticles thin film was deposited onto the interdigited electrodes to fabricate the humidity sensor device. The humidity adsorption and desorption properties of the sensor were studies. The sensing mechanism of the humidity device can be explained by complex impedance analysis.

Czts Thin Films

Cu2ZnSnS4 generally abridged as CZTS is a potential material for economical thin film solar cells, due to its appropriate band gap energy of around 1.5 eV and great absorption coefficient of above 104 cm-1. All the constituents of this material are plentiful in the earth’s crust, and they are non-hazardous making it an elegant alternative. Subsequent to the early achievement of the CZTS based solar cell with its light to electrical conversion efficiency of 0.6%, significant advancement in this research area has been attained, particularly in the last seven years. Currently, the conversion effectiveness of the CZTS thin film solar cell has enhanced to 24%. More than 500 papers on CZTS have been available and the greater part of these converses the preparation of CZTS thin films by diverse methods. Until now, many physical and chemical methods have been engaged for preparing CZTS thin films. Amongst them, spray pyrolysis is a flexible deposition technique. Spray pyrolysis is a simple deposition technique that finds use in widespread areas of thin film deposition research. This method is appropriate for depositing good quality films with low cost, clean deposition, and simplicity and flexibility in the manufacturing design. This script, reviews the synthesis of CZTS semiconductor thin films deposited by spray pyrolysis. This analysis initiates with a portrayal of the spray pyrolysis system, and then establish the CZTS and preparation of the CZTS precursor for coating. A review of spray pyrolysis of CZTS thin films are discussed in detail. To conclude, we present perspectives for advancements in spray pyrolysis for a CZTS based solar cell absorber layer.

In this work, the influence of the substrate temperature on properties of cobalt oxide thin films has been reported. Cobalt oxide thin films were prepared by electrostatic spray deposition technique on glass substrate at different temperature of the substrate. The properties of cobalt oxide films were characterized by X-Ray diffraction (XRD), scanning electron microscope, Raman spectroscopy, UV-visible spectrophotometer, respectively. In additional, the crystalline structural parameters can be performed from XRD data. Phase transformation of cobalt oxide films due to different substrate temperature was observed. Moreover, the optical properties of films were depended on the quantity of phase transition in cobalt oxide film.

ABSTRACTThin films of BaCe0.8Y0.2O3-δ (BCY) were prepared by colloidal spray deposition. Dense, crack-free BCY films having a grain size of 2–7 μm were successfully deposited on NiO/BCY substrates. Electrochemical hydrogen pumping with the BCY films showed that the maximum current density increased with temperature. The maximum current density was sensitive to the moisture in the cathode gas; the value obtained with a dry cathode gas was only half that with a wet cathode gas. A very high hydrogen-pumping current density of 3.4 A/cm2 was measured at 700°C with an applied voltage of 1.5 V.
