    N-Annulated Perylene as a Coplanar π-Linker Alternative to Benzene as a Low Energy-Gap, Metal-Free Dye in Sensitized Solar Cells A new perylene dye that displays an 8.8% power conversion efficiency at an irradiance of the AM1.5G sunlight is synthesized. This is the highest efficiency achieved so far by a metal-free pyrelene dye. Time-resolved photophysical and electrical measurements are performed to analyze the charge transfer dynamics that contribute to the photovoltaic performance.

  2. Device Area Scale-Up and Improvement of SWNT/Si Solar Cells Using Silver Nanowires

    Article first published online: 19 APR 2014 | DOI: 10.1002/aenm.201400186

    Power loss due to parasitic resistance limits the scale-up of nanocarbon/Si solar cells and, here, a viable approach that mitigates this problem is reported. The direct solution casting of silver nanowires (AgNWs) onto the single-walled nanotube (SWNT)/silicon junctions leads to a significant improvement in photovoltaic properties owing to enhanced carrier transport in the bilayer AgNW/SWNT composites, implying a great potential for wafer-scale nanocarbon/Si solar cells with relatively high efficiency.

  3. An Aqueous Sodium Ion Hybrid Battery Incorporating an Organic Compound and a Prussian Blue Derivative

    An aqueous sodium ion hybrid battery consisting of disodium naphthalenediimidesalt (anode) and KCo0.5Cu0.5Fe(CN)6 (cathode) is reported. Both electrode materials are inexpensive and exhibit appropriate operating voltages and robust reversibility under neutral aqueous electrolyte conditions, delivering a full-cell voltage of 1.1 V with 88% capacity retention after 100 cycles.

    The Influence of Nanocrystal Aggregates on Photovoltaic Performance in Nanocrystal–Polymer Bulk Heterojunction Solar Cells

    Marcus L. Böhm, René J. P. Kist, Frederik S. F. Morgenstern, Bruno Ehrler, Salvatore Zarra, Abhishek Kumar, Yana Vaynzof and Neil C. Greenham

    The influence of nanocrystal aggregates on photovoltaic deviceperformance is studied in a CdSe:poly[2-methoxy-5-(3′,7′-dimethyloctyloxy)-1,4-phenylene vinylene] (MDMO-PPV) bulk heterojunction solar cell. The exclusion of CdSe aggregates yields a superior blend morphology leading to improved charge generation and better percolation in the nanocrystal component. Solar cells with treated nanocrystals show a significant increase in device performance.

    Flexible, free-standing, and binder-free graphene-based V2O5 composite electrodes that do not require current collectors are fabricated into a prototype supercapacitor device exhibiting a performance of 52.5 mF cm–2 (157.51 mF), with the total electrode mass reaching up to 20 mg. One unit of the assembled prototype device is capable of powering up a commercial gadget consisting of eight light-emitting diodes.
