Abstract

Ferroelectric thin films have been used for different applications in the fields of electronics and electric-optics. Barium Strontium Titanate (BST) is very attractive ferroelectric material and becomes the center of attention due to its various advantages, including low optical losses, low dielectric constant and high storage capacity. The purpose of this research is to find the optical and crystal structure properties of thin-film Ba0,55 Sr0.45Tio3 (BST)1 M. Annealing time was 15 hours at a temperature of 750°C and 775oC on p-type silicon subtract by using chemical solution decomposition (CSD) methods which is followed by spin coating process at 3000 rpm for 30 seconds. Optical properties test such as absorbance and transmittance analysis, showed that the increase in the annealing temperature can improve the absorbance properties and energy gap of BST. Energy gap obtained by using tauc plot are 3.05 eV for the annealing temperature of 750°C and 3.225 eV for the annealing temperature of 775oC. Crystal structure by X-Ray Diffraction (XRD) showed that the difference in annealing temperature causes a shift in the angle of diffraction. The pseudo tetragonal structure of Ba0,55 Sr0.45Tio3 becomes tetragonal (c / a <1) and the crystal structure have crystal orientation distribution.

Abstract

This paper presents the design of DC micro grid with a load-based battery discharge method for remote island electrification utilising marine currents and solar photovoltaic. To anticipate the intermittent, a load-based battery discharge method is proposed. A centralized battery storage is sized according to the unfilled load demand by the marine current and the solar PV. Thus, the length of the turbine diameter is varied to meet the optimum system size. Hourly data of marine current speed from Cipalulu Strait in Maluku, Indonesia is provided. Data at a typical time, shows that the marine current peak power occurs every 6 hours perday, whereas the PV is at noon. The loads divide into 6 categories, including household 1, household 2, villagse office, school, mosque, and public health center with the peak demand as 112 kW and 856 kWh perday. All loads, mainly for lightings and electronic equipment work in 24 V DC through converters. The distribution network employs 320 V DC connecting from the power plan to the community residents. Simulations demonstrate that the battery size, solar PV, and turbine radius matches to meet the loads. Simulations also show that the battery utilization meets its current and capacity, meaning that an optimum size and filling the load profile can be smoothly conducted.
