    Abstract Cadmium telluride (CdTe) thin film solar cells have gained significant attention in the photovoltaic industry due to their high efficiency and low cost. CdTe solar cells have achieved a high‐power conversion efficiency of 23.1%. To further boost the device's performance, it is crucial to systematically tune the doping concentration and carrier concentration, which are dominated by the doping approach and the following dopant activation processes. Both Group I elements (e.g., Cu) and Group V elements (e.g., As) doping have demonstrated high efficiency and utilizing various doping techniques. This review provides an overview of the history of the CdTe thin film technology, doping mechanisms, doping techniques, challenges, and potential solutions to further improve device performance.
