Fabrication and Characterization of Spin Coating Deposited Thin Film Aluminium/BaTiO3 and Pelletized Copper, MnO2/BaTiO3 Capacitor

Abstract

Thin film capacitor using Aluminium (Dielectric-Barium Titanate) and pelletized Copper, MnO2 (Dielectric-BaTiO3) capacitors as substrates were constructed. The objective of this research was to develop a capacitor having high capacitance and dielectric strength. The attention was focused on the high dielectric strength of BaTiO3 and high capacitance of MnO2, so that we can develop a good capacitor. The dependence of stacked and single forms of above capacitors with respect to various electrical parameters were analysed using LCR meter. On the basis of graphs plotted for various electrical parameters such as impedance, quality factor, dissipation factor, conductance, series and parallel capacitance were analysed from the above graphs. By analysing the comparison between Aluminium (Dielectric-Barium Titanate) single and stacked forms the conclusion that I arrived was that stacked form is more preferable over single forms. Taking consideration of copper, MnO2 (Dielectric-BaTiO3) capacitor stacked forms were found to be better than single forms. Thus it was clear that the stacked form of Aluminum (Dielectric-Barium Titanate) and stacked forms of copper, MnO2 (Dielectric-BaTiO3) capacitor is more preferable while using as capacitors. Although a variety of renewable energy technologies as well as new storage devices have been developed, they have not reached wide spread use. Therefore, there is a strong need of development of improved methods for storing energy when it is available and retrieving when it is needed. The ability to store energy when it is produced is an essential waypoint on the road to turning alternative energy into regular energy. This problem of storage can be solved by supercapacitor. It is an emerging technology in the field of electrical energy storage and its use along with battery or fuel cell is viewed as a solution in many portable systems.
