The Future Circular Collider (FCC-ee), currently in the Feasibility Study phase, is an electron-positron collider designed for various operational modes, including Z, W, H bosons, and ttbar. To achieve high luminosity, it requires a high-intensity, low-emittance positron source. This presentation will provide a brief overview of the FCC-ee injector complex and focus on the positron source. It will cover ongoing studies on two positron production schemes: conventional and crystal-based, emphasising their performances. Finally, will conclude with a description of the developed simulation models and experimental studies, including an overview of the proof-of-principle positron source experiment at PSI (P3) aimed at validating the proposed positron source design.
