The reasonable design of materials plays a crucial role in improving the power conversion efficiency (PCE) of organic solar cells (OSCs). In recent years, OSCs have achieved great success in the research of donor and acceptor materials, making a significant contribution to the rapid growth of efficiency. Currently, their maximum efficiency is over 19%, demonstrating their great potential in practical applications. Chlorine-mediated strategy is proved to be an effective method to regulate the properties of the donor and acceptor materials and has important application significance. Through efforts, our research group has gradually formed a “Chlorine-Mediated Organic Photovoltaic Materials System” based on the continuous progress and accumulated achievements. In this perspective, the development of a series of representative chlorine-mediated polymer donor and non-fullerene acceptor materials using chlorine-mediated strategies in recent years are briefly introduced. The ability of chlorine atoms to regulate material energy levels, intermolecular stacking, active layer film morphology, and their important effects on the photovoltaic performance of devices were emphasized, and their intrinsic mechanisms were explored. In addition, some key issues such as efficiency, cost, and stability that should be considered when developing next generation chlorine-mediated organic photovoltaic materials in the future are also discussed.
