  1. Synergy Between Metal Oxide Nanofibers and Graphene Nanoribbons for Rechargeable Lithium-Oxygen Battery Cathodes

    Jun Yin, Joseph M. Carlin, Jangwoo Kim, Zhong Li, Jay Hoon Park, Bharat Patel, Srinivasan Chakrapani, Sangho Lee and Yong Lak Joo

    Article first published online: 18 OCT 2014 | DOI: 10.1002/aenm.201401412

    Graphene nanoribbons (GNRs) unzipped from carbon nanotubes and zinc oxide (ZnO) nanofibers with a high degree of defects and hydrophilicity of the surface are promising cathode components for rechargeable lithium-oxygen batteries. The optimum synergy between ZnO nanofibers and GNRs together with inclusion of catalysts, such as platinum, can balance the discharge capacity and cycle life.

  2. A Comparison of Five Experimental Techniques to Measure Charge Carrier Lifetime in Polymer/Fullerene Solar Cells

    Five experimental techniques that measure charge carrier lifetime are applied to an organic solar cell and compared. At high charge carrier densities, all the techniques surprisingly provide similar lifetimes. At low charge carrier densities, deviations to apparent high reaction orders are observed.

  3. The Effect of Fluorination in Manipulating the Nanomorphology in PTB7:PC71BM Bulk Heterojunction Systems

    Shuai Guo, Jing Ning, Volker Körstgens, Yuan Yao, Eva M. Herzig, Stephan V. Roth and Peter Müller-Buschbaum

    Article first published online: 18 OCT 2014 | DOI: 10.1002/aenm.201401315

    The nanomorphology of novel fluorinated polymers PTB7-Fx (fluorine units coupled with submonomer thieno[3,4-b]thiophene):[6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) bulk heterojunction films for photovoltaic applications is comprehensively investigated using both direct imaging and scattering techniques. Absorption properties, film morphology, film crystallinity of the photoactive layers, and the corresponding solar cell performance are consecutively probed. The reason for different photovoltaic performance with varied degrees of fluorinated PTB7 and the efficiency-morphology relationship are addressed.

  4. Enhanced Environmental Stability of Planar Heterojunction Perovskite Solar Cells Based on Blade-Coating

    Jong H. Kim, Spencer T. Williams, Namchul Cho, Chu-Chen Chueh and Alex K.-Y. Jen

    Article first published online: 18 OCT 2014 | DOI: 10.1002/aenm.201401229

    A simple and effective method to prepare air-processable perovskite films is ­developed. The blade-coated ­perovskite films feature self-assembled ­air-protection patches, and solar cells based on these film showed significantly improved air-­stability with high power conversion efficiencies up to 9.52%. It is also ­demonstrated that the blade-coating process is applicable to the fabrication of high efficiency (12.21%) perovskite solar cells.

  5. Fast Li Storage in MoS2-Graphene-Carbon Nanotube Nanocomposites: Advantageous Functional Integration of 0D, 1D, and 2D Nanostructures

    A 3D porous composite consisting of nano-0D MoS2, nano-1D carbon ­nanotubes, and nano-2D graphene is prepared using an electrostatic spray deposition technique. Either nanodots of amorphous MoS2 (0.5–5 nm) or nanocrystalline few-layered MoS2 (5–10 nm) bonded to graphene-carbon nanotubes backbone are obtained. Such ­composites show excellent rate performance and ­superior cycling stability.
