| 1 | Near-infrared organic photoelectric materials for lightharvesting systems: Organic photovoltaics and organic photodiodes显示文摘The inherent advantages of organic optoelectronic materials endow lightharvesting systems,including organic photovoltaics(OPVs)and organic photodiodes(OPDs),with multiple advantages,such as low-cost manufacturing,light weight,flexibility,and applicability to large-area fabrication,make them promising competitors with their inorganic counterparts.Among them,nearinfrared(NIR)organic optoelectronic materials occupy a special position and have become the subject of extensive research in both academia and industry.The introduction of NIR materials into OPVs extends the absorption spectrum range,thereby enhancing the photon-harvesting ability of the devices,due to which they have been widely used for the construction of semitransparent solar cells with single-junction or tandem architectures.NIR photodiodes have tremendous potential in industrial,military,and scientific applications,such as remote control of smart electronic devices,chemical/biological sensing,environmental monitoring,optical communication,and so forth.These practical and potential applications have stimulated the development of NIR photoelectric materials,which in turn has given impetus to innovation in light-harvesting systems.In this review,we summarize the common molecular design strategies of NIR photoelectric materials and enumerate their applications in OPVs and OPDs. | Boming Xie Zhongxin Chen Lei Ying Fei Huang Yong Cao | 2020 | InfoMat2020，2，1： | 3 |
| 2 | Stretchable transparent electrodes for conformable wearable organic photovoltaic devices显示文摘To achieve adhesive and conformable wearable electronics,improving stretchable transparent electrode(STE)becomes an indispensable bottleneck needed to be addressed.Here,we adopt a nonuniform Young’s modulus structure with silver nanowire(AgNW)and fabricate a STE layer.This layer possesses transparency of>88%over a wide spectrum range of 400–1000 nm,sheet resistance below 20Ωsq^(−1),stretchability of up to 100%,enhanced mechanical robustness,low surface roughness,and good interfacial wettability for solution process.As a result of all these properties,the STE enables the fabrication of a highly efficient ultraflexible wearable device comprising of both organic photovoltaic(OPV)and organic photodetector(OPD)parts with high mechanical durability and conformability,for energy-harvesting and biomedical-sensing applications,respectively.This demonstrates the great potential of the integration of OPVs and OPDs,capable of harvesting energy independently for biomedical applications,paving the way to a future of independent conformable wearable OPV/OPDs for different applications. | Nan Cui Yu Song Ching-Hong Tan Kai Zhang Xiye Yang Sheng Dong Boming Xie Fei Huang | 2021 | npj Flexible Electronics2021，5，1： | 1 |
| 3 | Distribution of Mid-deeply Buried Sand-bodies and their Hydrocarbon Significance at Basin Margins: Case Study of the Paleogene in the Eastern Liuzan Area of the Nanpu Sag, Bohai Bay Basin, China显示文摘The current research aims to unlock the temporal and spatial distribution of sand-bodies and their relationship with hydrocarbon accumulation in the mid-deep layer of basin margins, located in the eastern part of the Liuzan area of the Nanpu Sag, Bohai Bay Basin, China. Through this study, the main target interval of the area was divided into two fourthorder sequences. The lean sand mixed sedimentary belt with great importance in controlling hydrocarbon accumulation was identified through the comprehensive use of 3 D seismic data, logging data, lithological data and seismic inversion data. A detailed analysis of sand-body development characteristics and their role in controlling hydrocarbon accumulation was conducted. The results reveal that the study area mainly develops two distinct fan-delta lobes from the NE-trending sediment supply direction. Due to the relatively high influence of the lacustrine transgression event, the scale of the lean sand mixed sedimentary belt within the SQ1-1(the lacustrine transgressive systems tract) is relatively small, showing a relatively continuous distribution of sand bodies in the plane. Conversely, due to the relatively high impact of the lacustrine regression event, the scale of the lean sand mixed sedimentary belt developed within the SQ1-2(the highstand systems tract) is relatively large, the two east sets of fan-delta sedimentary systems being clearly separated. The lean sand mixed sedimentary belt formed a good lateral occlusion belt in favor of hydrocarbon accumulation. Through composite analysis of structural interpretation results, sand-body distribution and well test data, it is evident that the lean sand mixed sedimentary belt located in the structural high is not a favorable zone for hydrocarbon accumulation. In contrast, the wing of the high part of the structure is the zone of sand-bearing bodies and is a favorable zone of hydrocarbon accumulation. | CUI Lijie JIAN Shikai ZHANG Boming XIE Xiongju LI Liang | 2021 | Acta Geologica Sinica(English Edition)2021，95，4： | 0 |
