Organic solar cells (OSCs), as a promising photovoltaic technology, have made great progress recently due to the various optimization methods and designs of new materials. However, the general strategies show some restrictions on photovoltaic systems and commercialization of OSCs. Insulating polymers with low costs exhibit rich functionality, enhance device performance, and stabilize film morphology in air or at a high temperature. Herein, the strategies of the ternary, interface layer, and block copolymer in insulator‐modified OSCs (i‐OSCs) reported in recent years are highlighted. In addition, the corresponding underlying mechanisms, such as crystallinity, self‐assembly, dipole interaction, and charge transfer, are also discussed. The applications of insulating polymers in OSCs open a novel avenue for optimizing device performance and bestow a potential pathway to achieve large‐scale industrial production in the future.
