  1. Optimization of Carbon- and Binder-Free Au Nanoparticle-Coated Ni Nanowire Electrodes for Lithium-Oxygen Batteries

    Sun Tai Kim, Nam-Soon Choi, Soojin Park and Jaephil Cho

    Article first published online: 22 SEP 2014 | DOI: 10.1002/aenm.201401030

    Au nanoparticle-coated Ni nanowire substrates are used as the electrode (Au/Ni electrode) for Li-O2 batteries. This optimized Au/Ni electrode demonstrates improved capacity of ≈600 mAh g−1Au. More importantly, it exhibits improved cyclability over 200 cycles at full discharge and charge conditions between 2.3 and 4.3 V.

  2. Electrochemical Design of Nanostructured ZnO Charge Carrier Layers for Efficient Solid-State Perovskite-Sensitized Solar Cells

    Jie Zhang, Philippe Barboux and Thierry Pauporté

    Article first published online: 22 SEP 2014 | DOI: 10.1002/aenm.201400932

    Efficient perovskite-sensitized solar cells are prepared based on designed electrodeposited zinc oxide scaffold layers. They combine Cl-doped vertically oriented nanowire arrays and an intermediate thin overlayer of low n-type doped ZnO. Very large photocurrents and open-circuit voltages are achieved and a power conversion efficiency as high as 10.28% is demonstrated.

  3. Direct Observation of Ordered Oxygen Defects on the Atomic Scale in Li2O2 for Li-O2 Batteries

    Dongdong Xiao, Shanmu Dong, Jing Guan, Lin Gu, Shanming Li, Nijie Zhao, Chaoqun Shang, Zhenzhong Yang, Hao Zheng, Chun Chen, Ruijuan Xiao, Yong-Sheng Hu, Hong Li, Guanglei Cui and Liquan Chen

    Article first published online: 22 SEP 2014 | DOI: 10.1002/aenm.201400664

    The structure of the discharge product, Li2O2, in lithium-oxygen batteries is revealed directly on the atomic scale. A unique stage ordering that the peroxide vacancy occupies preferentially in every other layer along the c-axis of Li2O2 is observed. This finding provides new insight into the relationship between the structure of Li2O2 and the discharge/charge behavior of Li-O2 batteries.

  4. Highly Efficient Flexible Hybrid Nanocrystal-Cu(In,Ga)Se2 (CIGS) Solar Cells

    Yu-Kuang Liao, Maël Brossard, Dan-Hua Hsieh, Tzu-Neng Lin, Martin D. B. Charlton, Shun-Jen Cheng, Chyong-Hua Chen, Ji-Lin Shen, Lung-Teng Cheng, Tung-Po Hsieh, Fang-I Lai, Shou-Yi Kuo, Hao-Chung Kuo, Pavlos G. Savvidis and Pavlos G. Lagoudakis

    Low-cost pulse-spray deposition is used to incorporate self-assembled clusters of luminescent nanocrystal quantum dots (NQDs) into a flexible thin-film Cu(In,Ga)Se2 (CIGS) solar cell. Luminescent down-shifting and internal scattering on NQD clusters are found to provide a large broadband improvement of the quantum efficiency, yielding a 10.9% relative increase of the efficiency.

  5. A High Power-Density, Mediator-Free, Microfluidic Biophotovoltaic Device for Cyanobacterial Cells

    Paolo Bombelli, Thomas Müller, Therese W. Herling, Christopher J. Howe and Tuomas P. J. Knowles

    Article first published online: 16 SEP 2014 | DOI: 10.1002/aenm.201401299

    A soft-lithography microsolidics approach is demonstrated for the fabrication of biophotovoltaic devices that do not require membranes or mediators. Cyanobacteria settled on the microanode permit the physical proximity between cells and electrode required for mediator-free operation. Using these devices power densities of above 100 mW m–2 under white light are obtained for a chlorophyll concentration of 100 μM.
