The enhancement of the current-carrying capabilities of cuprate materials depends highly on the knowledge of how to tweak their doping state. The recent efforts on overdoping YBa \(_2\) Cu \(_3\) O \(_{7-\delta }\) (YBCO) to push the limit of critical current density towards the depairing critical current density are also based on the study of their doping state. We present the overdoping study of Transient Liquid Assisted Grown YBCO films through various oxygenation strategies, including oxygen-ozone mixtures and Ag surface-decoration layers. We systematically analyze how the key kinetic parameters, such as temperature, dwell time, ozone concentration, and surface modification, influence the oxygen content and superconducting properties of the films. Our results provide insights into achieving the overdoped regime in TLAG YBCO and offer a comparison with films grown via the Pulsed Laser Deposition (PLD) method. This study of overdoping on the TLAG YBCO films, which compares three distinct oxygenation methods and conducts an unprecedented analysis of the ozone-assisted process, promises a substantial enhancement in REBa \(_2\) Cu \(_3\) O \(_{7-\delta }\) (REBCO, RE = rare earth elements) fabrication.
