Large Crystalline Domains and an Enhanced Exciton Diffusion Length Enable Efficient Organic Solar Cells Zhang, Yiwei; Sajjad, Muhammad T.; Blaszczyk, Oskar; Parnell, Andrew J.; Ruseckas, Arvydas; Serrano, Luis A.; Cooke, Graeme; Samuel, Ifor D. W. We studied crystallinity and exciton harvesting in bulk heterojunctions of the semiconducting polymer PffBT4T-2OD and electron acceptor PC71BM that are used to make highly efficient organic solar cells. Grazing incidence wide-angle X-ray scattering shows that the size of crystalline domains of PffBT4T-2OD increases to ?18 nm in photovoltaic blends upon…

Overcoming the energy loss in asymmetrical non-fullerene acceptor-based polymer solar cells by halogenation of polymer donors Fan, Qunping; Liu, Tao; Gao, Wei; Xiao, Yiqun; Wu, Jingnan; Su, Wenyan; Guo, Xia; Lu, Xinhui; Yang, Chuluo; Yan, He; Zhang, Maojie; Li, Yongfang To achieve efficient polymer solar cells (PSCs), it is important to overcome the energy loss (Eloss) from the optical bandgap to the open-circuit voltage (Voc) of the device by properly matching donor/acceptor (D/A) photovoltaic materials. Here, we develop efficient PSCs based on the absorption complementary pairs of halogenated polymer donors…

The Influence of Structure and Morphology on Ion Permeation Behaviour in Commercial Silicone Hydroge

Saez-Martinez, Virginia; Mann, Aisling; Lydon, Fiona; Molock, Frank; Layton, Siân A.; Toolan, Daniel T. W.; Howse, Jonathan R.; Topham, Paul D.; Tighe, Brian J.

The Influence of Structure and Morphology on Ion Permeation Behaviour in Commercial Silicone Hydrogel Contact Lenses Saez-Martinez, Virginia; Mann, Aisling; Lydon, Fiona; Molock, Frank; Layton, Siân A.; Toolan, Daniel T. W.; Howse, Jonathan R.; Topham, Paul D.; Tighe, Brian J. The importance of the microstructure on the permeability of silicone hydrogels is widely appreciated but is poorly understood and minimally investigated. In contrast with most conventional hydrogels, the water content and water structuring within silicone hydrogels cannot be solely used to predict their permeability. To ensure comfort and eye health,…

OrderOrder Phase Transitions Induced by Supercritical Carbon Dioxide in Triblock Copolymer Thin Films Abate, Anabella A.; Vu, Giang Thi; Piqueras, Cristian M.; del Barrio, María Cecilia; Gómez, Leopoldo R.; Catalini, Gabriel; Schmid, Friederike; Vega, Daniel A. We study the influence of supercritical carbon dioxide (scCO2) on the phase behavior of a cylinder-forming polystyrene-block-polybutadiene-b-polystyrene triblock copolymer thin film. Solvent annealing with scCO2 can produce patterns with long-range order but these structures become unstable for thin films with small thicknesses. These results are in good agreement with self-consistent…

Highly Crystalline Near-Infrared Acceptor Enabling Simultaneous Efficiency and Photostability Boosting in High-Performance Ternary Organic Solar Cells Yin, Hang; Zhang, Chujun; Hu, Hanlin; Karuthedath, Safakath; Gao, Yajun; Tang, Hua; Yan, Cenqi; Cui, Li; Fong, Patrick W. K.; Zhang, Zhuoqiong; Gao, Yaxin; Yang, Junliang; Xiao, Zuo; Ding, Liming; Laquai, Frédéric; So, Shu Kong; Li, Gang The near-infrared (NIR) absorbing fused-ring electron acceptor, COi8DFIC, has demonstrated very good photovoltaic performance when combined with PTB7-Th as a donor in binary organic solar cells (OSCs). In this work, the NIR acceptor was added to state-of-the-art PBDBT-2F:IT4F-based solar cells as a third component, leading to (i) an efficiency increase…

Ambient synthesis of nanomaterials by in situ heterogeneous metal/ligand reactions S. Chang, Boyce; Thomas, Brijith; Chen, Jiahao; D. Tevis, Ian; Karanja, Paul; Çınar, Simge; Venkatesh, Amrit; J. Rossini, Aaron; M. Thuo, Martin Coordination polymers are ideal synthons in creating high aspect ratio nanostructures, however, conventional synthetic methods are often restricted to batch-wise and costly processes. Herein, we demonstrate a non-traditional, frugal approach to synthesize 1D coordination polymers by in situ etching of zerovalent metal particle precursors. This procedure is denoted as the…
