  1. Supercapacitors Performance Evaluation

    Sanliang Zhang and Ning Pan

    Article first published online: 12 DEC 2014 | DOI: 10.1002/aenm.201401401

    Inconsistencies in supercapacitor performance evaluation severely hinder progress in this important field of electrical energy storage. Clarifications are made in this article to identify the inconsistencies and their causes. Proper solutions are proposed to facilitate the production of reliable, intrinsic, and comparable performance metrics for supercapacitors.

  2. Unraveling the Morphology of High Efficiency Polymer Solar Cells Based on the Donor Polymer PBDTTT-EFT

    The morphology of a novel and highly efficient polymer solar cell is comprehensively investigated using surface sensitive near-edge X-ray absorption fine structure spectroscopy and bulk-sensitive grazing incidence wide angle X-ray scattering. The solvent additive 1,8-diiodooctane in particular is shown to be effective at controlling fullerene aggregation and enhancing polymer ordering, facilitating efficiencies of over 9%.

  3. Shelf Life Degradation of Bulk Heterojunction Solar Cells: Intrinsic Evolution of Charge Transfer Complex

    Antonio Guerrero, Hamed Heidari, Teresa S. Ripolles, Alexander Kovalenko, Martin Pfannmöller, Sara Bals, Louis-Dominique Kauffmann, Juan Bisquert and Germà Garcia-Belmonte

    Article first published online: 12 DEC 2014 | DOI: 10.1002/aenm.201401997

    Long-term stability analysis under non-accelerated conditions reveals spontaneous chemical interaction between bulk materials. Device degradation occurs by the formation of donor–acceptor charge transfer complexes that act as exciton quenchers. Generation of these radical species diminishes photocurrent and reduces open-circuit voltage by the creation of electronic defect states.

  4. Design Meets Nature: Tetrahedrite Solar Absorbers

    Jaeseok Heo, Ram Ravichandran, Christopher F. Reidy, Janet Tate, John F. Wager and Douglas A. Keszler

    Article first published online: 12 DEC 2014 | DOI: 10.1002/aenm.201401506

    Computational inverse design and consequent experimental results allow for the identification of new tetrahedrite-mineral compositions as promising absorber candidates in drift-based thin-film solar cells. In device simulations, cell efficiencies above 20% are modeled with absorber layers as thin as 250 nm. These new compositions thus open opportunities for realization of a new class of high-efficiency thin-film solar cell.

  5. One-Step Solvothermal Synthesis of Nanostructured Manganese Fluoride as an Anode for Rechargeable Lithium-Ion Batteries and Insights into the Conversion Mechanism

    A favorable MnF2 anode is successfully synthesized based on ionic liquid and it delivers surprisingly inspiring electrochemical performance, with a capacity retention of 237 mAh g−1 at 10 C after 5000 cycles. Redistribution of metallic Mn nanoparticles within the LiF matrix, resulting in the formation of Mn network facilitating electron transport, is considered as the dominant cause for improvement of reversibility and capability.
