Despite the recent breakthroughs of polymer solar cells (PSCs) exhibiting a power conversion efficiency of over 17%, toxic and hazardous organic solvents such as chloroform and chlorobenzene are still commonly used in their fabrication, which impedes the practical application of PSCs. Thus, the development of eco-friendly processing methods suitable for industrial-scale production is now considered an imperative research focus. This Review provides a roadmap for the design of efficient photoactive materials that are compatible with non-halogenated green solvents (e.g., xylenes, toluene, and tetrahydrofuran). We summarize the recent development of green processing solvents and the processing methods to match with the efficient photoactive materials used in non-fullerene solar cells. We further review progress in the use of more eco-friendly solvents (i.e., water or alcohol) for achieving truly sustainable and eco-friendly PSC fabrication. For example, the concept of water- or alcohol-dispersed nanoparticles made of conjugated materials is introduced. Also, recent important progress and strategies to develop water/alcohol-soluble photoactive materials that completely eliminate the use of conventional toxic solvents are discussed. Finally, we provide our perspectives on the challenges facing the current green processing methods and materials, such as large-area coating techniques and long-term stability. We believe this Review will inform the development of PSCs that are truly clean and renewable energy sources.

环保的聚合物太阳能电池：绿色溶剂加工和材料设计方面的进展
尽管聚合物太阳能电池（PSC）的功率转换效率超过17％的最新突破，但在其制造过程中仍普遍使用有毒和有害的有机溶剂，例如氯仿和氯苯，这阻碍了PSC的实际应用。因此，现在认为开发适合工业规模生产的环保加工方法成为当务之急。该评论为设计与非卤代绿色溶剂（例如，，二甲苯，甲苯和四氢呋喃）。我们总结了绿色加工溶剂的最新发展以及与非富勒烯太阳能电池中使用的高效光敏材料相匹配的加工方法。在使用上更加环保的溶剂，我们进一步审查进度（即（水或酒精），以实现真正的可持续性和环保型PSC制造。例如，引入了由共轭材料制成的水或醇分散的纳米颗粒的概念。此外，讨论了开发完全消除使用常规有毒溶剂的水/醇溶性光敏材料的最新重要进展和策略。最后，我们就当前绿色加工方法和材料所面临的挑战（例如大面积涂覆技术和长期稳定性）提出了自己的看法。我们认为，此次审查将为真正清洁和可再生能源的PSC的发展提供信息。
