All-polymer solar cells (all-PSCs) have attracted considerable attention due to their inherent advantages over other types of organic solar cells, including superior optical and thermal stability, as well as exceptional mechanical durability. Recently, all-PSCs have experienced remarkable advancements in device performance thanks to the invention of polymerized small-molecule acceptors (PSMAs) since 2017. Among these PSMAs, PY-IT has garnered immense interest from the scientific community due to its exceptional performance in all-PSCs. In this review, we presented the design principles of PY-IT and discussed the various strategies employed in device engineering for PY-IT-based all-PSCs. These strategies include additive and interface engineering, layer-by-layer processing methods, meniscus-assisted coating methods, and ternary strategy. Furthermore, this review highlighted several novel polymeric donor materials that are paired with PY-IT to achieve efficient all-PSCs. Lastly, we summarized the inspiring strategies for further advancing all-PSCs based on PY-IT. These strategies aim to enhance the overall performance and stability of all-PSCs by exploring new materials, optimizing device architectures, and improving fabrication techniques. By leveraging these approaches, we anticipate significant progress in the development of all-PSCs and their potential as a viable renewable energy source.
