However, substantial energetic disorder in active layer materials severely limits device performance under low-light conditions, presenting a major challenge for indoor photovoltaic applications. In this study, we have designed and synthesized four novel non-fullerene acceptors (NFAs) incorporating vertical acenaphthylene derivatives via halogen substitution strategies, namely GWQ20, Z3, Z4, and Z5, tailored specifically for indoor optoelectronic applications. Z3, Z4, and Z5 show much suppressed non-radiative energy loss and reduced energetic disorder but poor charge generation and recombination than GWQ20. Subsequently, for further device performance enhancement under indoor condition, it’s necessary to combine their distinct advantages via ternary strategy. As a result, target ternary devices based on Z4/Z5 both perform much better performance: 25.8 %/25.6 % vs 20.8 % under 1000 lux LED, and 30.1 %/30.2 % vs 26.8 % under 2000 lux LED, attributed to simultaneously minimized energy loss and protected charge behavior. These results are appealing the cutting-edge level of the field. Beyond efficiency, we herewith demonstrate that reducing energetic disorder is a key factor to improve the free carrier generation for indoor performance improvement, which could be instructive for future development of material design and device optimization on this type of OPVs.</div></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"166 ","pages":"Article 101066"},"PeriodicalIF":31.6,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144679521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the out-of-plane polarization distribution of Moiré superlattices in twisted h-BN (t-BN) with a small twist angle is meticulously delineated using piezoelectric force microscopy (PFM) with quadrature phase differential interferometry (QPDI) analyzer. The polarization of AB/BA stacking domains and saddle points regions has been detected, where opposite polarization regions exhibit a 180 degrees phase difference. The strain within the Moiré pattern significantly alters the polarization distribution at saddle points regions, leading to pronounced differences in the electromechanical behaviors between the inner Moiré domain and domain wall regions. Moreover, <em>in-situ</em> stress can modify the saddle points regions, leading to an expansion of these regions and a larger electromechanical response with increasing stress.

Biodegradable or edible packaging films based on biopolymers have attracted considerable attention due to their sustainability. However, the comprehensive properties of current biopolymer films, such as mechanical strength and barrier performance, are still inferior to those of petroleum-based plastic films. Therefore, efforts have been devoted to improving the performance of biopolymer films. Nature-inspired bionics, especially mussel-inspired bionics, has become increasingly important in materials science and has been widely applied in biomedicine and environmental engineering. Recently, functionalization using mussel-inspired catechol derivatives like dopamine and tannic acid (TA) has emerged to improve mechanical, barrier, and functional properties of biopolymer packaging films and edible coatings. This study overviews biopolymer packaging development, focusing on mussel biomimicry mechanisms. Notable applications of dopamine, TA, and other catechol derivatives in creating innovative biopolymer packaging materials are described to advance research in this field. The key finding of this work is that mussel-inspired catechol derivatives can be integrated into packaging films through a variety of methods, leveraging their ability to participate in multiple physical and chemical interactions. The resulting composite films exhibit various functionalities, including strong interfacial adhesion, photothermal effects, UV absorption, and free radical scavenging. These properties enable them to serve multiple roles in packaging matrices. Edible coatings based on mussel-inspired strategies enhance adhesion and improve interfacial interactions between the coating solution and the food surface, thereby improving the preservation effect of edible coatings. Therefore, mussel-inspired functionalization of catechol derivatives is an effective strategy to enhance the performance of food packaging films and coatings.</div></div>","PeriodicalId":386,"journal":{"name":"Materials Science and Engineering: R: Reports","volume":"166 ","pages":"Article 101068"},"PeriodicalIF":31.6,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144656115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
