Self-healing polymers (SHPs) with dynamic covalent bonds or non-covalent bonds have emerged as an innovative solution to enhance the durability of PSCs through autonomous damage healing. Although SHPs have been proved to be quite promising for enhance the reliability of PSCs, there is still lacking systematic molecular design strategies tailored for practical cooperation SHPs with versatile types of PSCs. Herein, this review systematically organizes the recent research progress of self-healing PSCs from the perspective of application-oriented design principles. The self-healing mechanisms of PSCs using SHPs under chemical and mechanical damage modes are first comprehensively explored, and a multi-dimensional self-healing evaluation system is proposed. Subsequently, the distinct effects of SHPs as additives, interfacial modifiers, and encapsulation materials in PSCs are summarized. More importantly, the incorporation methods of SHPs in PSCs and the structural characteristics of representative SHPs are systematically analyzed, with application-specific design principles for optimized performance proposed. Finally, the challenges and opportunities in the optimization of self-healing material properties, in situ characterization techniques, and scalable fabrication are outlined. This work aims to facilitate the transition of SHP-based self-healing PSCs from laboratory research to real-world applications, providing a roadmap for future developments in this emerging field.</p>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02087-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147351115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, scalable fabrication of high-density OTFT arrays for active-matrix applications remains highly challenging, primarily due to the incompatibility of conventional photolithography with organic semiconductors. Here, we report an all-photolithographic strategy that enables the scalable fabrication of flexible OTFT arrays with both high device density and superior charge transport characteristics. By combining synergistic interfacial modulation and dual-protection photolithography strategy of organic semiconductors, we successfully fabricated transistor arrays exhibiting an average mobility above 1.0 cm<sup>2</sup> V<sup>−1</sup> s<sup>−1</sup> and on/off ratios of ~ 10<sup>5</sup>. This scalable method further enables an integration density of 6.25 × 10<sup>4</sup> cm<sup>−2</sup>, which is one of the highest densities reported to date for full-photolithographic OTFT active-matrix arrays. Moreover, we demonstrate seamless integration of OTFT active-matrix arrays with organic light-emitting diodes (OLEDs), yielding all-organic active-matrix OLED (AMOLED) arrays. These devices exhibit stable electroluminescence, ultralight weight (~ 24.3 g m<sup>−2</sup>), excellent flexibility, and skin-like display functionality with reliable pixel-level addressing. This work establishes a universal and scalable route toward high-density organic electronic systems, opening new opportunities for flexible displays, electronic skin, and next-generation wearable technologies.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2026-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-026-02107-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147351142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
