Abstract Significant advancements in power conversion efficiency have been achieved organic solar cells with small molecule acceptors. However, stability remains a primary challenge, impeding their widespread adoption renewable energy applications. This review summarizes the degradation of different layers within device structure under varying conditions, including light, heat, moisture, and oxygen. For photoactive layers, chemical pathways polymer donors acceptors are examined detail, alongside morphological bulk heterojunction structure, which plays crucial role performance. The mechanisms commonly used anode cathode interlayers electrodes addressed, as these significantly influence overall stability. Mitigation methods for identified provided each section to offer practical insights improving longevity. Finally, an outlook presents remaining challenges achieving long‐term stability, emphasizing research directions that require further investigation enhance reliability performance real‐world
