Research Abstract

YBa2Cu3Oy superconducting films were grown fabricated by a chemical solution deposition process. The solution deposition is a promising process for coated conductor fabrication due to its cost efficiency. In this process, impurities such as water in starting solution has been one of the big problems because when YBCO film was fabricated by a solution containing high water concentration, the crystal orientation of the film become worse. In this study, water in starting solution was purified by controlling two factors, degree of vacuum and holding period in vacuum. Two-step vacuuming process enabled us to decrease the water concentration effectively. The water concentration of the solution with purification was one third of the solution without the purification. And, we obtained highly oriented YBCO films by using the purified solution. Consequently, current property enhanced to be 4 times in comparison to the film prepared by the solution without purification.
