Electrochemical Impedance Spectroscopy (EIS) Analysis of BTA Removal by TMAH during Post Cu CMP Cleaning Process

ABSTRACTIt is of great significance to understand and monitor the condition of the commercial batteries in EVs/HEVs and stationary applications under their real working situations. Electrochemical impedance spectroscopy (EIS) has been proved to be a powerful technique for investigating the kinetics and redox reactions at the interfaces, as well as the diffusion behavior in the bulks of every electrochemical systems. Focusing on tracing the temperature of the commercial batteries during the EIS tests at different stages in a well-designed four-week driving simulation, the value of temperature profile during the EIS test as an enhanced indicator to help analyzing the formation of the passivation layers, electrolyte impedance development as well as lithium plating on the anode through EIS analysis have been found.

The effect of Methylammonium Iodide (CH3NH3PbI3) perovskites (MIP) concentration on the performance of perovskites sensitized solar cell (PSC) was studied. Three MIP concentrations, namely 0.2, 0.4, and 1.0 M were prepared. In this study PSC with a sandwich structure of ITO/TiO2/ MIP /electrolyte/ Pt film was fabricated for this purpose. It was found that power conversion efficiency (PCE) increased with the increasing the concentration of MIP, from 0.01 to 0.21 % as the concentration increase from 0.2 to 1.0 M. Photoluminescence (PL) study showed that the increase of the MIP concentration decrease therecombination of carrier in the device. Electrochemical impedance spectroscopy (EIS) analysis also shows that with the increased of MIP concentration results in the decreased of the Rct due to the improvement of the carrier transport in the devices.

In this study, the formation of porous Al2O3 on commercial 1050 aluminium alloy (AA1050) in 2[Formula: see text]M sulfuric acid (H2SO4) electrolyte was investigated. Anodization was performed at 12[Formula: see text]V and 15[Formula: see text]V specimens for a charge density of 757[Formula: see text]mC/cm2 and 3231[Formula: see text]mC/cm2. The resulting oxides were analyzed using scanning electron microscopy (SEM). According to analysis, a hexagonal oxide formation containing more than one nano pore was observed on the surface of the specimen. The structural properties of the porous oxide film were analyzed with electrochemical impedance spectroscopy (EIS) analysis and film-related features such as thickness of the porous and the barrier layer were obtained.
