Polymer/small molecule/fullerene based ternary solar cells have made great progress and have attracted considerable attention in recent years. The addition of small molecules can effectively compensate for the disadvantages of polymer solar cells, such as increasing the light‐harvesting ability, providing cascade energy levels, and tuning the morphology. Thus, polymer/small molecule/fullerene based ternary solar cells are promising candidates to obtain further improvements in photovoltaic performance for organic solar cells. This article summarizes the developments of ternary solar cells with small molecules as third components, and represents the possible photo‐physics process in the ternary blends. In addition, the challenges and perspectives for ternary solar cells are discussed.
